Perpendicular and Parallel Rolling

   Perpendicular bat rolling is a process that rolls a softball or baseball bat through two plastic or hard rubber rollers (although the bat rollers we utilize are of an undisclosed material). This rolling process will roll the entire length of the bat as it passes through the rollers on approximately a quarter inch line on both the top and bottom of the bat. The bat is rolled on 8-12 points around the bat, which breaks in most of the bat as it runs through the rolling machine. Now that the bat has been rolled on 8 to 12 points perpendicularly there will be peaks and valleys along the length of the bat. These highs and lows are created by rolling bats along certain points and not all points. Here lies a catch 22; the bat needs to be rolled completely for Optimal Distance Results but if it is rolled perpendicularly on too many points around the bat the potential for cracks increases substantially. When the bat goes through the rollers perpendicularly the rollers flatten the bat causing the resin (or glue) to break up, this is what gives the extra flex and makes bat rolling appealing to players. When the bat is rolled perpendicularly along too many points the area of the bat gets rolled twice, thrice, or maybe 4 times too much, causing weak spots or cracks in the composite. Perpendicular bat rolling will break in your bat but not to its fullest potential; that is where the parallel rolling completes the job.

   Parallel bat rolling is a process that rolls the traditional sweet spot of the bat. As you could guess the bat is placed parallel in the bat rolling machine. The theory behind this is that the entire sweet spot of the bat would be rolled with out missing any areas within the sweet spot. Some bat rolling machine builders have taken the idea a little too far by expanding the length of their rollers to encompass the entire barrel. This type of bat roller is destined to cause problems. The composite flexes about 1 1/2 inches past a parallel roller and if you use a roller larger than 6 inches it could break the composite in the taper or end cap area. The parallel rolling machine should be utilized after it is run through a perpendicular rolling machine. This will allow the parallel bat rolling machine to break in any sections the perpendicular bat rolling machine missed. The peaks and valleys that were discussed earlier will be flattened out by breaking up the resin and glue in those areas. This is the most consistent and even bat rolling you can accomplish. As a stand alone the parallel bat roller will work, as long as it has the shorter rollers (around 6 inches, which is the length of a sweet spot). The longer rollers will not roll a bat consistently and there is the danger of breaking a bat at the taper and end cap area because of the extended flex a longer roller yields.

We will roll your new or used bat to achieve Optimal Distance Results, increasing distance 20-40 feet of your batted ball. We are the first bat rolling company to realize the effectiveness of Perpendicular Rolling followed by Parallel Rolling and all have followed suit. We are fully confident in our technique and this is the only type of Bat Rolling we offer. This method has been proven (see Science of Bat Rolling Page) to produce the greatest results and has become the industry standard in the bat rolling community. You might hear that Parallel rolling machines will put too much stress on the bats barrel (and this is correct with longer rollers) but we roll with the Premium, Hard plastic, 6 inch rollers on our machines. Our bat rolling machine are capable of rolling perpendicular and then parallel. The parallel bat roll actually breaks in the sections that a perpendicular only roll will always miss. We make around 300 bat rolling passes on your bat (perpendicular and parallel). While rolling we gradually increase the pressure to create a consistent break in and increased durability. We have bat rolled thousands of bats and have developed the best techniques to optimize the distance and durability of your bat. We stand behind our bat rolling service and will reroll your bat if you are not completely satisfied. In Addition, We guarantee that if we break your bat in the rolling process we will replace your bat. We are a professionally run bat rolling company that understands that quality and customer satisfaction comes first!

Bat shaving is a bat modification that decreases the thickness of a bat’s barrel. The end cap is removed and a digital precision lathe “shaves” the inside of the barrel or increases the diameter. The decrease of composite allows the barrel to flex more when hitting a ball, this flex equals greater batted ball speeds. The increased ball speed can add 40-60 feet with shaving alone, add perpendicular and parallel bat rolling prior to shaving and that number jumps even higher.

There are many people who open up a bat and shave
the inside with a drill hone (cylinder hone). A hone will
create “hot spots” and “dead spots” through out the
shaved barrel. A hot spot is where the spot is shaved
too much and the barrel will flex more. This sounds
good because we want more flex for more distance,
right? Not exactly, the hot spot will cause a weak spot
on the barrel and increase the chance of breaking
significantly. There are predetermined widths for bat
shaving, which test the limits of the bat as far as
strength and durability. Honing past these limits will
cause your bat to break prematurely. The dead spots
are just the opposite of hot spots; they cause the bat
to flex less, which causes a decrease in distance. A
bat straight from the factory will often have
inconsistencies of 5-10 thousands of an inch along the
barrel already. The precision lathing of your bat will
actually create the most accurate wall available. A consistent wall allows the bat to have the same flex around the bat for increased distance and better longevity (remember, a shaved bat is less durable). The main point is that sanding the inside of a barrel will never be consistent or precise, only a lathe can do that. A lot of people who shave on EBay (and even some on the internet) use a drill hone (cylinder hone); this is why you will see cheap prices on EBay for shaving services. The lathe should have a digital read out to lessen the chance of inaccuracies. One pass through the lathe is not as accurate as taking out material in 2-3 passes. It would be like using coarse grit sand paper as opposed to a fine grit sand paper. The fine grit will take longer but it produces a better product. When the bat is taken out of the lathe it will have lost around 1 ounce of material depending on the manufacturer of the bat (different bats have different bat shaving specifications). The shaved weight needs to be put back into the bat at the handle and end cap, an extra amount can usually be put into the cap for an end load. If you did not know, all manufacturers create their barrels to weigh the same. They put metal weight into the handle and extra resin into the end cap to weight the bat anywhere from 26 ounces to 30 ounces. After the weight is added back the end cap is put back on using the correct resin (substandard resin could result in the end cap separating and even popping off) and we are finished.
