Weather, Topography, and Ball Motion

THE INSIDE LINE: 2011/01/18

In the first issue of THE INSIDE LINE, we promised that our next article would discuss how weather affects topography and ball motion. Since lanes are made up of wood, and sub components of wood, we know temperature will affect the shape of them.  However, the one part of weather that significantly affects the shape of lanes is the humidity, or lack thereof.

Because wood is porous, and high humidity means there is a lot of moisture in the air, humidity tends to make wood swell up. Low humidity, when there is very little moisture in the air, makes wood compress as the moisture is not as present in pores of the wood. For those that have seen what happens to wood approaches when a spilled drink was left there too long, you know the effects.  Bowling lanes do the same thing.

Humidity and Temperature

When bowling lanes and wood based components that make up lanes are exposed to humidity and temperature changes, extra moisture in the air often "enters" the wood material at a point of least resistance. But because there are many differences in construction, and depending on the sub-foundation material and underlayment, as well as the many different wood components utilized in building a bowling lane, the only thing we can be sure of is weather definitely changes lane shape.  However how it changes can vary greatly from situation-to-situation.

For instance, often the outer edges of certain materials, like wafer board Parallel Strand Lumber (PSL), are much more susceptible to moisture penetration from the sides rather than from the top. This contamination happens much faster than moisture penetration elsewhere, so in this case the swelling causes a depression.

In other instances, swelling causes the wood, or boards, to compress against each other which can cause a “push up” effect. In this case swelling can cause a crown, or less of a depression.

But how does this affect lane conditions? First, lane conditions in this case are not about the oil pattern, it’s about the condition of the lane. Time has altered the term lane conditions to mean only oil. This was not the case for the majority of time modern bowling has been in existence. So in this case, we’ll discuss lane conditions as it relates to the shape of the lane, and how those shapes affect ball motion.

Depressions and Ball Motion

If weather change makes your lanes become depressed, this shape not only helps guide the ball towards the center of the lane, it also makes the ball lose energy faster. The reason for this increased loss of energy is the rotational effect of the bowling ball against the side hill of the depression.

Here is a graphical example:

As you can see, for a right-handed player, or left-handed back-up bowler, the rotation of the ball is counter clockwise to the slope, and therefore acts like the ball is trying to rotate uphill. This makes the ball lose energy faster versus a flat lane. When lanes are shaped in this manner, ball motion is more of an “arcing” type motion because of the early loss of energy. This loss of energy is also the root cause of why some houses are referred to as a “10-pin center”.

The majority, if not all, wood lanes are depressed, especially in the head area. The majority of synthetic lanes installed over wood lanes are depressed, especially in the front part of the lane. We have found that new synthetic lane installations are more random; some parts of the lane are depressed, some parts are crowned, some are high left, and some are high right. But they are still affected by humidity and temperature changes, which means the randomness remains, it’s just different.

We have documented examples that show certain type lane structures can depress 70/1000” when weather changes occur. To show how much this affects the bowling ball, we have taken Kegel’s adjustable lanes, shaped them, and performed many tests.

Our testing has shown that a bowling ball released at 18 mph on a lane that is depressed 40/1000” from the edge to the center, can cause the bowler to be over three boards left from that of the flat lane. Slower ball speed players and lighter balls are affected more. Faster ball speed players and heavier balls are affected less. This is in accordance with Newton’s Laws of Motion.

Crowns and Ball Motion

To get an idea how a crown affects the energy of the bowling ball by its rotation, here is the same type graphical example as before:

As you can see, now the bowling ball is rotating with the slope of the lane, which causes the bowling ball to lose less energy than it would if it was rotating against the slope of the lane. When a lane is crowned in this manner, high launch angles will be affected more than a bowler that plays “straighter up the boards”.  When lanes are shaped in this manner, ball motion is also more “skid snappy” because the bowling ball is retaining more energy.

The Race Track Effect

Because of this rotational effect and gravity, lanes that are depressed in the heads act like there is very little oil in the front part of the lane. Depressed heads are no different than driving your car on a banked curve. The reason for banked curves on the road, or race track, is that they reduce the vehicle’s dependence on friction to navigate the curve.

It’s no different on a bowling lane. Depressed heads keep the ball from “squirting” away from the pocket, or in other words, help the ball make its move towards the pocket, just like a banked race track helps the car turn the corner. That is, until the bowler lays the ball down on the other side of the depression.

Did you ever wonder why players that can get far to the left make the lanes look easy? The next graphic shows why; gravity is now working to their advantage, instead of against them.

The bowling ball now has a gravity “push to the right” in the front part of the lane, and a gravity “bank shot” once down the lane. Gravity wise, the lane is helping the ball get to the right early with energy retention, and then return to the pocket in the breakpoint area. Players that don’t have the rev rate to get to the extreme left are at a tremendous disadvantage in this type of playing environment.

Notice that during this entire article, we have shown how lane shape affects the direction of the bowling ball, how lane shape affects the shape of the ball’s motion, and how lane shape affects the energy loss of the bowling ball, yet we have not mentioned lane conditioner or the oil pattern once!

The next time you start chasing down a ball motion issue at your center, or even a pin carry issue, and you have performed the Process Verification Procedure on your lane machine and oil pattern, don’t overlook the shape of your lanes. We have a relatively new saying at Kegel; “you can’t fix a gravity problem with oil.”

In conclusion, get to know your lanes; identify how they’re shaped and how weather change affects their shape. Find out why some lanes score high, and why some lanes score low. It will save you a lot of headaches, and help you provide your customers with a high-quality playing experience all year round. And like always, if you have any questions or need help, call Kegel.

Lane Conditions and Cold Snaps

In last month's article, we touched base on some of the effects weather can have on lane machines, lane conditioner, and ball motion. We wrote about these effects in the sense that the environment has already become more stable. But because of a few recent technical calls, we have decided to release a Special Edition of THE INSIDE LINE, and continue the discussion on how weather can affect lane conditions.

We have found that the biggest problem in a bowling center occurs when there is a drastic and quick temperature change. Kegel's lead chemist and VP of Chemical Product Development, Dennis Sheirs, found this out during the U.S. Open in 1998. For the first two days of the tournament the air conditioner wasn't working in the bowling center, and it was 80 degrees inside the center, and on the lanes.

Sometime in the middle of the afternoon on the second day of the tournament the air conditioning was fixed. Then during that evening someone cranked the air conditioning way down and by the next day both the bowling center, and the lane temperature were 60 degrees.

The bowlers started practice that morning and found the lane pattern played 10 boards tighter. Luckily, since Kegel was doing the lanes and strictly following our Process Verification Procedure, we could prove it wasn't because the laneman or lane machine did something different. But we did learn a valuable lesson; when doing lanes take control of the climate control system!

How does this affect you in daily life?

We find the same thing can happen when you typically get a cold snap up north and it's instant. Normally you will see everything get a little tighter at first. Then as everything goes through equilibrium, and bowling centers kick on the heat, all the other properties change and eventually everything will settle back in. That's when the lanes will start to hook more from the point where they got tighter at.

We said before that when the temperature of lane conditioner gets lower, the viscosity goes up, but that's only one part of the equation. The other part of the equation is the surface tension also increases, which makes the lane conditioner move more until everything settles back down. This can last over a week because during a cold snap the whole system is in flux.

What else can the weather do to my lanes?

During the summer time when the humidity is typically greater, synthetic lanes on top of wood lanes tend to be a bit more crowned towards the gutter outside of the second arrow. We know from our testing, crowned lanes tend to create "hang spots".

But in the winter time, when the heat is turned on in the bowling center or humidity decreases, the wood lane tends to depress, or the crowns decrease, and the panels follow that change in lane shape. This makes it easier for the ball move more towards the center - in other words, hook more. That change however takes a few weeks to fully occur.

If your located in an area that gradually gets colder throughout the year, you won't experience drastic changes because everything is just slowly moving there.

But from our experience, in most scenarios, those quick "cold snaps" (change from warm to cold), tend to make lanes play tighter first. Then, as the inside environment equalizes and the heater settles things down, lanes depress, and that's when we see more hook again.

So as we stated before, typically in the summertime, synthetic lanes installed over wood lanes tend to crown a little bit, and in the winter time, they tend to depress. When measuring lanes using the Kegel LaneMapper, we have documented examples of lanes changing up to .070" from summer to winter and back again - high humidity can create crowns and low humidity releases moisture causing the lane to depress.

In our research, we have found this drastic lane shape change happens only when synthetic panels are on top of existing older wood lanes. Synthetic panels on top of other substrates like MDF/HDF, or LSL do not show much change from summer to winter - only a few thousands of an inch.

Extreme lane shape change by overlays on top of wood lanes is caused by the wood lane underneath becoming "looser and looser" from years of not receiving attention as they did when resurfaced regularly. Basically, the toes screws that hold the boards together, and the screws holding the wood lane to the levelers, start backing out from the constant pounding of the bowling ball, making the wood lane act like an accordion.

What do we suggest for quick weather changes?

Don't respond to the change too fast - give everything a chance to settle down and get back into equilibrium. Most of the time, our first response is we have to change something when somethings goes haywire - it's human nature.

You are better off to first perform your Process Verification Procedures to ensure your machine is operating correctly, your cleaner is being mixed correctly, and if so, just let everything settle down. Otherwise, you're going to be trying to change something while everything is transitioning.

A non-bowling analogy to the transition is like when you get into a pool for the first time. The water may feel cold, and that could be your first reaction, but if you stay in for a little while, you start to adjust to the temperature.  Your core body temperature does not change; you just begin to acclimate to it.

After everything have settled down though, it may be entirely possible you have to adjust your oil pattern in order to keep your bowlers closer to what they are used to. For that just give us a call - the Kegel LaneMapper has provided us with insight and allows us to provide answers much quicker than in the past.

To end, and we can't stress enough, every center is unique and the solutions to any problems are just as unique. Just know that Kegel's Tech Support department is full of dedicated people trying to do the same thing you are; provide our customers with the best possible experience as we can.

Kegel Road Trip Seminar Videos

During the year 2010, Kegel, along with Storm Bowling, performed a series of seminars throughout the USA. Kegel's portion of the seminar focused on some interesting variables that make up the playing environment.

The You-Tube videos below are of Chris Chartrand presenting Kegel's portion of the seminar. After watching these videos, you will find that there are many things about bowling you probably have never thought of, or even knew about. Enjoy.

The Weather’s Changing…Are Your Lane Conditions?

It’s that time of year again. Leagues began towards the end of summer, the pattern gets tweaked, and everyone starts to get back into the swing of things. Everything is going great and then boom, the weather gets colder and all of a sudden things are different. Then comes the question every manager and mechanic has heard more than they can count - "What happened?"

The products that a bowling center uses to create optimal lane conditions; like lane machines, conditioners, cleaners, and even the lanes themselves, are all physical in nature and therefore temperature dependent. So as temperature changes, the properties and performance of all those products will change as well.

So how do changes in those physical properties show up in the bowling center? They show up in lane machine performance, oil pattern differences, lane topography changes, and of course, what the bowlers feel and see in ball reaction. As the temperature of the conditioner gets colder, the viscosity, surface tension, and density all increase which not only affects ball motion, this also affects different lane machines in different ways.

For this article, we will discuss these changes and offer advice on how to minimize the effects of cold weather on lane conditions. We will focus on the products used to condition the lanes, and in the next issue, we will move on to discuss the topographical changes the lane surface goes through as the climate changes.

Lane Conditioner
In early 1997, we conducted several tests to see how much conditioners changed when the temperature was raised or lowered. What we found was eye-opening. The viscosity of some conditioners changed 2 cps (centipoises) for every 1° F of temperature change. That means if you start with a 20 cps (viscosity) conditioner and the temperature drops from 80° F to 70° F, the viscosity of that conditioner would be 40 cps.

This is not true for all lane conditioners. Some only change 1 cp for every 2° F of temperature change. That is only 25% the change as some of the others, but regardless of how much they change, it's important to know that all of them do.

To minimize this change, look for a conditioner with a higher viscosity index (VI). VI is a way of assigning a value to a conditioner’s resistance in viscosity variation as the temperature changes. The manufacturer of your conditioner should be able to give you this value and guide you accordingly.

Lane Machines
For centers using wick technology lane machines, if the conditioner or lane machine is not kept at normal room temperature, or if stored near a cold wall, the oil will “thicken” and impede the wicking action which reduces conditioner flow onto the lane. As it gets colder, the capillaries in wicks shrink, also restricting flow. Therefore the oil pattern that you started out with at the end of summer might not be the same oil pattern as the weather gets colder.

For centers using Kegel Sanction Technology™, like the IKON, FLEX, and Kustodian line of lane machines, temperature decrease will not affect the output of conditioner like it will in a wick machine. However, if the conditioner gets colder, what you may see is the pressure in your oil pump gauge increase. Fortunately, this does not change the output of conditioner; that’s the beauty of Kegel’s Sanction Technology.

For Sanction Technology lane machine owners, Kegel’s Steve Cross suggests the following when seeing slight pressure fluctuations:

- DON'T PANIC! Expect pressure fluctuations because it is normal with temperature changes.

- Do not change the tubing (pressure regulator). Many people will try to put in a shorter tube to decrease the pressure, but this is not necessary. We have designed a large margin for psi and still have the machine perform as intended. Pressure alone does not affect oil output in Sanction Technology machines.

- Do not adjust the fluid metering pump to adjust pressure. Adjusting the fluid metering pump will increase and decrease the amount of conditioner output (volume).

- Get the machine out early, turn on the oil pump motor, and let it run for about 10 minutes. You should see the psi gauge go back to normal.

Our tech support department receives many calls this time of year with temperature related concerns and we recommend the following no matter what lane machine or lane conditioner you are using:

- Keep the lane conditioner in a temperature controlled environment. The office, front desk, or wherever the temperature is most constant.

- Keep on top of your chemical orders; try to place orders a few weeks in advance to give the chemicals a chance to “acclimatize.”

- Keep the lane machine in a temperature controlled environment so the machine functions properly. If that is not possible, look for other solutions like an electric blanket, packing blanket, or a space heater to help keep the machine warm.

Ball Motion
As we stated before, when conditioner gets colder, the viscosity, surface tension, and density increase. With the increase of these physical properties, more resistance is created on the bowling ball as it rolls through the conditioner. This, in return, usually causes the bowling ball to slow down faster which means it will hook a little more.

Another byproduct of colder weather is the conditioner tends to “stay in place” more which reduces carrydown and therefore, helps the backends stay stronger longer.

Not every bowling center is affected by outside temperature changes but if yours is, our technicians have a couple tips you can employ:

- If when the weather gets colder you notice the bowling balls are hooking more, increase your oil pattern by one foot. This will help bring back the hold area you had when the season began. Once the weather warms back up, decrease the pattern length back to what it was when the season began. Note: Wood lanes with overlays can change in shape which may increase this affect; read about "Changing Lanes".

- If you find temperature changes tend to affect your lane conditions, try to use a lane conditioner that is more resistance to temperature change (higher VI index). Kegel’s Offense HV (for Sanction Technology machines only) is such a product. Offense HV was created when Kegel was entrusted with lane maintenance for the PBA Tour. It was designed to minimize the difference in ball motion from the weekly competition to the TV Show. The TV Show uses many very hot lights that are not present during the rest of the week’s competition. To this day we use Offenses HV when we perform tournaments in venues with less than ideal climate control.

Keep in mind there is no magic lane conditioner or oil pattern that is best for every lane surface or bowling center. Finding a conditioner and oil pattern that is best for your center takes some research and a lot of patience.

Sir Isaac Newton Knows Bowling

Sometimes pictures, or in this case a picture and a video, explains it best. The video below is the championship match of the Trio’s event at the recently concluded WTBA World Men’s Championship. The picture is the Kegel LaneMap™ of lanes 11-12 at Dream Bowl Palace.

The final match was played on the WTBA Mexico City oil pattern which is fairly flat and 45' in length. Our after bowling tapes showed the optimum breakpoint was around the 10-11-12 boards on that oil pattern at this championship.

The ball tracks of the left-handers and right-handers during the trios championship match are on top of the LaneMap™ Slope Graphs.

Sir Isaac Newton, the father of gravity, was not surprised with the ball motion of the players during this match - Newton has known for a long time that gravity has the same influence on the bowling ball as friction, or lack thereof.

The green areas on the LaneMap™ have very little gravitational influences on the bowling ball. The light blue and orange areas are significant gravitational influences on the bowling towards the direction of the arrows. The red and dark blue areas are severe gravitational influences on the bowling ball towards the direction of the arrows.

Now watch the video below and see if you can see and understand what Sir Isaac Newton already knew. He has been whispering in our ear for many years that it's not always oil or lack of oil (friction), as the reason the bowling ball reacts differently from one lane to the next, or even in certain areas of the same lane.

Pay attention to the right lane and how many light hits the right-handed players have. Then look at the above Slope Graphs in the break point area. Those blue areas signify a significant slope to the right - which is why the ball has a hard time moving to the left. Slopes to the right beyond the oil pattern (for a right-hander) acts like "carrydown". But it's not carrydown causing those light hits - it's gravity,

Bowling Bedlam - Oil

The playing environment of bowling today may be as complex, unpredictable and chaotic as any time in the history of the game. We're not talking about the weekly league or club game where the participants just want to have fun. We're talking about professionally maintained and controlled tournament environments where bowling sports people compete.

It is in this type of sporting environment, along with the basic premise of playing well both physically and mentally, that the decisions the modem player makes will ultimately determine whether they perform up to their expectations or have to wait until the next event comes around.

This is the second in a series of articles that will try to shed some light on many of the variables in the current game of bowling and why the players of today need to be very open minded and aware of the total environment at all times when competing. The supplied information is all in the quest of understanding and to increase performance, not to create excuses.

Oil (Conditioner)

There are low viscosity oils and high viscosity oils. There are oils with different amounts of additives such as friction modifiers and flow agents for different types of lane machines. There are oils with varying surface tensions which help the oil bond to the lane surface.

Mineral oil is used in most lane conditioners as the base oil but over the years lane conditioner has evolved. Today's conditioners are now mixed with a percentage of specialized additives to increase the performance and durability of the conditioner.

All these different types of conditioners will make your bowling ball react differently on the lane. At the same time, different types of conditioner can make the same pattern play different.

If using a wick machine, some conditioners will flow through the wicks more than others making the same pattern settings apply a different pattern. With wick machines, temperature will affect the flow rate since temperature not only affects viscosity or the thickness of the conditioner, it will affect the size of the capillaries of the wicks as well.

If using spray type machinery, different conditioners will either peel off or hold onto the buffer brush more or less which can change the shape of any specific pattern even though the machine settings remain constant. Different lane surfaces will do the same thing so add that into the equation also.

There is a very good online article by Kegel's Chris Chartrand on lane conditioner (oil), "10 Things That Everyone Should Know about Lane Conditioners" which you can view by clicking on the title. Therefore we won't go into specific details on all conditioner properties but one thing we will touch base on is viscosity since the USBC has just made a new specification on this lane conditioner property.

The new viscosity rule the USBC has implemented "requires that lane conditioners used during USBC competition read between 12 and 81 centipoises at 70 degrees Fahrenheit." Centipoise (cps) is the standard unit of measurement for fluids and many lane oil manufactures will have this designated on their product.

Viscosity is very misunderstood in common bowling discussions. Most bowlers believe the higher the viscosity of oil, the "slicker" the bowling ball reacts to it. Actually the exact opposite happens.

By definition, viscosity is the measurement of internal friction of a fluid. The greater the amount of friction, the more force is required to move the fluid against itself which is called shear. Therefore the higher the viscosity, the more force it takes which increases friction. The lower the viscosity of oil, the less force it takes to shear which decreases friction.

In terms of a bowling ball rolling through these different oils, the higher the viscosity, the more resistance there is which makes the ball slow down more. When we get to the bowling ball portion of the series, we will spend more time on this subject but in short, friction is what makes the ball slow down and therefore enables it to hook.

Temperature is one of the biggest environmental factors in changing viscosity of a conditioner. So as the weather changes, so can the bowling conditions.

So what is the purpose of viscosity in lane oils? In short to provide durability to an oil pattern however, because of the many different additives being used in today's oils, viscosity is not as important as it once was in regard to lane maintenance. But as a bowler, you should be aware of how it relates to ball motion.

Oil Patterns

This subject of oil patterns is a difficult one and probably the most blamed and misunderstood subject in bowling. Lane conditioning rules have changed many times over the years and even today with the USBC 'three unit rule' or the USBC Sport Bowling rule in place, there are an infinite number of pattern combinations and ways to apply an oil pattern to the lane.

Kegel's Founder and CEO John Davis had a saying when he was entrusted in doing lanes over the years which goes something like this;

"Its 4 o'clock in the morning and the tournament starts at 8:00. You know if you do this; this might happen. But if you do something else, that might happen. So what are you going to do? Who do you call? Who can you call? You have to do something but there is no book. It is all up to you."

In these simple questions lies the major dilemma for every laneman at every bowling tournament in the world. Only after the tournament do they ever know if the job was socially acceptable or unacceptable. In simpler words, did the laneman do a good job or a bad job?

Of course the laneman might ask the same question to the bowlers; when trying to figure out the conditions, did the bowlers do a good job or a bad job?

2008 EYC - When Everything Comes Together

The 2008 ETBF European Youth Championships at famed Tali Bowl in Helsinki Finland showed what can happen in the modern bowling environment when all parts of the scoring environment are predictable and at a high level. During the Championships, 12 of 15 girls scoring records were broken and 11 of 15 boys scoring records were broken. There were also five 300 games during the Championships. However, the closer you look and dissect the possible reasons why those records were broken and scores were achieved, the less anyone should be surprised.

The Players

The youth players of Europe are more knowledgeable than ever and the overall level of coaching is at an all time high. Add to the fact that eastern European countries are increasing in participation numbers and they are treating bowling as a sport. Even world renowned coach Sid Allen has been attracted to Europe being hired as head coach of Latvia. This proved to be a great move on the Latvian Federations part as it helped them achieve the country’s first Gold Medals in Major Championship events. In fact Latvia won a total of five medals during the Championships, 1-Gold, 3-Silver and 1-Bronze. A fine testament to what a solid coaching program can bring to a Federation.

The Scandinavian countries have long been setting the standard in Europe by developing great player after great player. The Finns, Swedes, Norwegians and Danes all took medals in the boys divisions and from watching the youth competition at the 2008 EYC, the Scandinavian’s still are generating many great players.

But there are also some very good up and coming youth players from other parts of Europe because of solid coaching programs and Federation support. We should look forward to watching them in future European Championships and tournaments like the European Bowling Tour for many years to come.

Another item coming into place within Europe is increased equipment knowledge which is a huge part of being successful in the modern game. Until now and mostly because of language barriers, Europe as a whole has been behind the learning curve of countries where English is spoken or understood in high numbers. That however is changing and they are catching up fast as was evident by observing ball choices at this event.

The Lanes

But back to the environment, the scoring or playing environment that is. Tali Bowl is somewhat of an anomaly in the world of bowling. Built in 1972, the Finns might have known something very few knew, or at least practiced, about the installation of bowling lanes. Even after the replacement of the wood lanes to Pro Anvilane synthetic panels, all lanes at Tali Bowl consistently have a certain topographical characteristic and the key word here is “consistently.”

Many of the synthetic lanes we have checked over the years have showed very little regularity with regard to topography throughout any specific lane but not Tali Bowl, all lanes follow the same topographical features throughout the entire lane surface. When lanes are installed in as a consistent manner as they are at Tali Bowl, players have to adjust very little as they move across the center during any one block of bowling.

As Team Norway Coach Trond Syvertsen said, “Only thing we did, was not to move too much and keep the ball rolling forward.”

Just imagine not having to take one, two or even three frames to figure out how the next pair of lanes is playing in relation to the last pair and only having to concentrate on releasing the ball the same way. This adds a minimum of 10 pins to the scoring pace right off the bat.

As far as the specific topographical character of the lanes at Tali Bowl, lanes can be crowned, flat or depressed. But because it has been requested by Tali Bowl representatives to not make certain aspects of the installation public, here is how different types of topography act to a bowling ball.

Crowned lanes act like a banked curve that is falling away from the apex of the turn. You won’t see race tracks built this way but we do see many lane surfaces that are installed this way.

As the bowling ball travels towards the channel, crowned lanes decrease the pressure between the ball and the lane which also decreases friction. This decreased friction of the bowling ball keeps the ball from slowing down at the normal rate and therefore also decreases the hook potential of the bowling ball.

Basically, on a lane that is crowned the bowling bowl is rolling down a hill as it travels towards the channel and then has to climb a hill as it makes it moves towards the pocket. This topographical property also decreases pin carry because it lowers the entry angle of the bowling ball into the pocket.

Crowned lanes are also more sensitive to release variations or ‘mis-hits’ which can cause inconsistent ball motions for the less repetitious player. For right handed players, the 2-10 spare combination is a common leave on lanes that are crowned.

Flat lanes, or lanes that are in the plus or minus 10/1000 of an inch range, are very rare in synthetic lanes of today but there are actually a couple documented examples. One is the Kegel Training Center in Florida. The other is the bowling center that held the USBC 5 person team scoring record of 3905, Chacko’s Bowl in Wilkes-Barre, Pennsylvania. That record was broken in 2004 but Chacko’s is still the host to the USBC Men’s three player team series record of 2443. Flat lanes provide the most predictable ball motion for the greatest variety of styles.

Depressed lanes act like a high banked curve at a race track. Just like a banked curve helps a race car turn easier, depressed lanes help the bowling ball curve back to the pocket easier.

As the ball travels towards the channel, depressed lanes increase the pressure between the ball and the lane which also increases friction. This increased friction of the bowling ball helps the ball slow down and therefore hook into the pocket with more regularity. This not only helps with consistent ball motion, it also helps with pin carry because it increases the entry angle of the bowling ball into the pocket.

And last but certainly not least is the lengthwise levelness of bowling lanes. Lanes that predominantly go downhill from foul line to pin deck make the bowling ball slow down less and therefore decrease hook potential. Lanes that predominantly go uphill from foul line to pin deck make the bowling ball slow down more and therefore increase hook potential. As in crowns and depressions, flat lanes are the most predictable for most styles.

An example of how lengthwise level affects ball motion is a bowling center Kegel checked during their lane maintenance years on the PBA Tour. In this particular bowling center, the high end always played significantly tighter than the low end which had lanes that were added on after the initial installation.

After mapping the entire center, the difference was found to be in the lengthwise levelness of the lanes. All lanes in the high end went downhill almost two inches from foul line to pin deck. The lanes on the low end were relatively flat.

As stated in the opening paragraph of this section, the most important thing about a bowling center installation is “consistency” in lane levelness from the first lane to the last lane. For the bowling player, this gives the most predictable ball motion from lane to lane and that equals the highest scoring potential. If there is one thing we can say about the bowling lanes at Tali Bowl, they have very consistent topographical features from lane to lane.

The Pin Carry

Tali Bowl has long been known for good pin carry. The pins used during the 2008 EYC were Brunswick Max’s but it was not the pins that made the difference, it was the lane installation plus the entire pit area at Tali Bowl. The side boards (kickbacks) are tight, the pin decks are solid and the pin spotting was good.

The last 300 game bowled in European Youth Championship history in the boys division was, you guessed it, at Tali Bowl in 1994. The first and only 300 game by a European girl was last year in Thessaloniki Greece at another consistent lane installation but that bowling center has since closed down.

The Oil Pattern

Ah yes, the oil pattern. The one thing everyone likes to focus on because it is invisible and therefore open to discussion, controversy, interpretation or whatever analytical word one can come up with.

Being a mixed youth event that employed a single condition, the main goal for the 2008 EYC lane maintenance team was to provide a playing environment where many different bowling styles had a chance to succeed. In order for that to happen, it was important to provide an oil condition that complimented the lane surface.

The pattern used for the 2008 EYC was 39 feet in length as announced in Bulletin II. Standard procedure in ETBF Championship events is to announce only the distance based upon the pre-tournament inspection which is normally six to nine months in advance.

At the 2008 EYC, oil pattern information was transparently provided to the teams like never before. As usual the teams were provided the lane machine settings, the forward volume, reverse volume and the total volume of conditioner. However this time they were also provided with the front-to-back taper ratios and side-to-side ratios.

For all ratio readings, USBC Sport Bowling calculations were used which averages the unit amount of conditioner from boards 18L to 18R divided by the average unit amount from boards 3 to 7. Currently, USBC Sport Bowling has the only official guideline for competitive oil patterns in bowling and states side-to-side ratios must be 3:1 or less. The WTBA and ETBF do not have definite oil pattern specifications so the goal for the 2008 EYC was to hit the high side of the USBC Sport Bowling ratio parameters.

The front-to-back taper ratios at the 2008 EYC were 2.2:1 on the inside and 2.7:1 on the outside portion of the lane. This means in the front part of the pattern there is 2.2 and 2.7 times the amount of conditioner in those zones compared to the amount at the end of the pattern. A 3D visual of the oil pattern was also provided.

Also shown to the coaches and players were the side-to-side ratios from six different tape readings. The pattern ratios at the 2008 EYC were 2.5:1 at 6 feet, 2.9:1 at 14 feet, 3.0:1 at 22, 27 and 32 feet and 3.2:1 at 37 feet using USBC Sport Bowling calculations.

In comparison, the side-to-side ratios of the 2008 EYC pattern were the same as the 2007 PBA Greater Detroit Open and PBA Spartanburg Open. In those PBA events, the ratio at the end of the pattern was also 3.2:1 but all PBA tournaments must pass USBC Sport Bowling standards. Therefore, the 2008 EYC pattern also passes USBC Sport Bowling and was on the same difficulty level as those PBA patterns.

Conclusion

Too many people think scoring pace is all about the oil pattern. Of course the oil pattern can make the scores higher or lower but so do many other abovementioned areas of the playing field.

However, should we not just have some specific oil pattern parameters and let the scores be what they are? Bowling should not penalize a good installation and reward a bad installation because of a perceived perfect scoring pace and until now, that is what bowling has been doing.

The play and competition during the 2008 European Youth Championships was fantastic. There are many very talented youth players in Europe right now and all the record breakers and medalists should be very proud of their accomplishments because they earned it.

I also hope the players realize how lucky they were to be able to compete in an arena like Helsinki Finland’s Tali Bowl. It is arguably one of, if not the best, bowling arena in Europe. And the ETBF European Youth record book proves it.

Bowling Bedlam - The Lane

The playing environment of bowling today may be as complex, unpredictable, and chaotic as any time in the history of the game. We’re not talking about the recreational league or club game where the participants just want to have fun, and the conditions are designed as such. We’re talking about professionally maintained and controlled tournament environments where bowling sports people compete.

It is in this type of sporting environment, along with the basic premise of playing well physically and mentally, that the decisions the modem player makes will ultimately determine whether they perform up to their expectations or have to wait until the next event comes around.

The players of today have to choose how to execute their delivery using which type of bowling ball, with which layout, with what surface preparation, on what lane surface, with what lane characteristic, on which oil pattern, and following what group of players. The player must also change this strategy rapidly and often during any specific round of play or throughout the course of an event.

This series of articles will try to shed some light on many of the variables in the current game of bowling and why the players of today need to be very open minded and aware of the total environment at all times when competing. The supplied information is all in the quest of understanding and to increase performance, not to create excuses.

The Lane

There is no question bowling balls of today are more frictional, hook more, and cover more area across the lane as it travels from the foul line to the pins. The modern core designs and coverstock compositions create more friction, which also makes the bowling ball more responsive to all the different variables that make up the playing environment.

There are different types of plastic film coated wood lanes which are the softest lane surfaces. There are wood lane surfaces coated different types of urethane which are the next hardest lane surfaces. The hardest and most common lane surfaces around the world now are synthetic lanes, with many different installation and friction characteristics.

We won’t get to deep into the specific manufactured hardness, friction, or wear properties of synthetic lanes, but keep in mind that all manufactured synthetic lane surfaces are different and how those surfaces wear from use is also not equal.

The USBC has performed studies that show some modern synthetic lane surfaces score best when brand new, some score better after a few years, peak, and then begin to score worse, while other surfaces score higher as wear and friction increases.

In regard to topography, the sanding techniques on wood lanes make those lanes much flatter than that of the installation of multiple synthetic panels. When a particular bowling center employed a strict resurfacing program, with skilled resurfacers, all the lanes in the bowling center was of high-quality and fairly consistent.

It is therefore a fair statement to say that wood lanes that are consistently resurfaced, screened, and re-coated on a consistent basis are more level than the synthetic bowling lanes of today.

One might think the contrary when only thinking about the synthetic panel itself. But when multiple panels are attached in sections on top of structures made up of other wood components, and more often than not on top of older wood foundations, it is easy to see the challenge for consistent levelness across a center using synthetic overlays. But it’s not impossible to achieve.

The current lane specification rules were written in 1937 by the American Bowling Congress, for wood lanes. The basics of the rule are the entire lane must be less level within plus or minus 40/1000 of an inch to be certified and approved for sanctioned play. The idea was that any groove deeper than the specification would allow too much guidance, or path correction, of the bowling ball after it was released by the bowler.

These level number limits also apply to crowns (hills), depressions (valleys), crosswise tilts, and lengthwise levelness. Surprisingly, only recently has the lengthwise level specification been added into the rules. The 40/1000 inch specification now reads “over 42 inches in any direction”, but only for new installations or centers that are changing from wood lane surfaces to synthetic overlays.

However, the overwhelmingly majority of the lanes are still inspected and passed by inspecting the lanes at only three predetermined points. These three inspection points are at a distance from the foul line between 10’-15’, 30’-40’ and 50’-55’. It is of course at these predetermined inspection areas installers of synthetic lanes pay most attention to.

Of course there are some very good installations and installers of synthetic lanes today but the reality is, installations are only as good as the time and care that is taken on a particular installation. Since the advent of synthetic lanes, achieving consistent levelness throughout a bowling center is a very difficult painstaking task and the tools and technology to level lanes in a more efficient manner have not been available. (Note: The recent invention of the Kegel Portable LaneMapper has made this process more efficient and attainable.)

Long time laneman and former PBA Lane Maintenance Director Len Nicholson states, “I’ve seen synthetics installed in 4-6-hours and they were legal according to the Sanctioning Body. This was in bowling centers that were changing over to synthetic overlays after their wood surfaces have reached their life limit. However, when the arena settings started on the PBA Tour and companies like AMF and Brunswick wanted to showcase their synthetic lanes, it would take them up to two days to get them as perfect as they could. And they were using their best installers performing the job on only four lanes!”

As the bowling ball travels down the synthetic lanes of today, it has to go slightly uphill sometimes, and then downhill at other times. The ball encounters random patterns of hills, valleys, and it encounters microscopic frictional differences, all without any uniformity.

By performing tests at the Kegel Training Center’s adjustable lanes in 1999 with top PBA professionals such as Parker Bohn III, Brian Voss and Jason Couch, it was proving that as little as 20/1000 of an inch, or 25 percent of the allowable tolerances, will affect the path and reaction of today’s highly responsive bowling balls.

These seemingly minute irregularities can cause a ball to increase its footprint which increases the friction between the ball and the lane. This will make the ball slow down more therefore increasing the hook potential. These topographical irregularities may also decrease the footprint between the ball and the lane which causes less friction. This makes the ball slow down less therefore decreasing the hook potential.

These random irregularities can make your intended shot possibly either hit the pocket heavy, light or in extreme cases even miss the pocket entirely.

When oil patterns that are designed to play more towards the outside portion of the lane are applied to bowling lanes which are predominantly crowned on the outside boards, it is difficult for the bowling ball to hook back into the pocket. Most short oil patterns are designed this way, and crowned lanes can make those patterns more difficult. However on longer oil patterns, or patterns designed to play more towards the inside portion of the lane, crowned lanes can sometime act like hold area which can increase mistake area.

On the other hand, bowling lanes that are depressed from the edge board can act like a race track with high banked turns on short oil patterns. The highest scoring lanes for short oil patterns are when lane topography is either slightly depressed or flat.

On long patterns however, depressions can take away hold area and make a long pattern more difficult since the ball will have a tendency to hook more. That is unless the player is on the other side of the depression. Then a depressed lane acts like that same banked race track a depression gives a player on a short pattern.

Unfortunately, rarely do synthetic lanes have a consistent character with regard to topography which makes it a challenge for both the players and the laneman.

For tournament players, depending on what lane a player begins their round on, these lane differences may determine a player’s equipment choice for the day or even where to play with no likeness of another. These choices can and often will cause the oil pattern to change in a different manner from day to day, squad to squad, pair to pair and even lane to lane.

A scenario often seen in leagues and tournaments throughout the world is when there are perceived differences in ball reaction, total blame is put on the oil condition when in fact most times it is the difference in the topography, surface friction of the lanes, or even the bowler themselves.

The below picture show a real world example of two lanes that make up a pair in a sanctioned bowling center.

The left lane of the pair is within specification, plus or minus 40/1000 inch, at most points throughout the lane. The right lane however has historically played notably different than its companion.

In this case, because of the extreme depression in the head area, and the excessive crowns in the mid lane and break point area of the lane, the right lane has always played considerably tighter. Basically the bowling ball is falling off the mountain in the midlane and then trying to climb the mountain as it begins it move towards the pocket. The depression in the head area also causes the ball to 'burn up' earlier which causes less back end movement. The players in this center say they are always lined up 4-5 boards different between these two lanes with the ball hooking much less on the right lane.

Take notice the points on the right lane that are within specification, which in this example are not many but only in the three aforementioned inspection areas. The left lane is also most level in those same three inspection areas.

Kegel has measured 1000’s of lanes and studied the scores of many different tournaments they have been associated with. They have found these topographical and frictional differences are the reason those “mystery pairs” tend to show up at bowling centers. It’s not always that those lanes or pairs are bad or out of specification and sometimes that one lane or those mystery pairs are actually flatter than all the other lanes. What makes them challenging is they are different than the others and players are trying to adjust to that one different lane off of all the others.

With all other things being equal, low scoring centers or tournaments are more about the lane surfaces throughout center being very irregular from lane to lane, while higher scoring can be more about the lane surface being very consistent from lane to lane.

In short, when centers have consistent topographical features from lane to lane, fewer adjustments from the players are needed.

Nicholson tells of an example from the PBA Tour at The Showboat in Las Vegas; “The TV Pair always played weird. The great PBA players always had problems. Scores on that pair were never up to par and eventually they changed the TV pair.”

If there is one thing you can take from this article, is to look at bowling lanes individually with each having their own unique characteristics. Don’t look upon a pair of lanes as both being the same or adjust to one lane in a pair off of the other lane unless you notice a specific trend in the center.

The balance between caring for the playing environment and it participants from the monetary pressures is one of bowling's sanctioning bodies’ greatest challenges. Our recreational fads will come and go with having to be continually reinvented to keep interest amongst those non-sporting customers. A healthy sport of bowling however will produce lifelong customers which every business person should want to create and sustain.
