Bat Shaving is a process in which the inner diameter of a composite bat is expanded (or decrease in wall thickness). This decrease of the wall thickness will cause an increased amount of barrel flex, which equals more distance when hitting a ball. The increased distance is anywhere from 30 to 60 feet to the batted ball..
The process involves the removal of the bat's endcap and shaving out 1 to 2 ounces of composite material. After the barrel is shaved, it is carefully put back together and the weight is redistributed to equal the original weight of the bat. This weight is added back to the handle and endcap. The endcap is then pressed back on to the top of the barrel with a high strength epoxy blend. The work is absolutely undetectable unless the endcap is taken off and the inner barrel is inspected. Poorly shaved bats can be detected by normal inspection. One obvious way is an endcap separation with epoxy showing. Another way is a poor choice of adhesive material. Can you imagine the cap coming off while hitting with your new bat? A novice bat shaver might use a different type of handle rod to reweight the bat or no handle weight at all. Each manufacturer has a certain handle rod and a well-informed person will be able to lift the knob sticker or tape and identify your bat as altered. Another easy way to tell if a bat has been altered is to simply weigh it. All manufacturers stick within about .4 ounces when producing a bat. For example: A 26 ounce Miken MV-3 Supermax weighs 26.3 ounces to 26.7 ounces. Therefore, if you weigh a MV-3 Supermax that is 26 ounces it has been altered in some way. An Easton weighs within .1 ounce of its stickered weight. A 26 ounce Easton will weigh 25.9 ounces to 26.1 ounces and is almost always exactly on the target weigh. So if you have a 26 ounce Easton that weighs 25.7 ounces, it has been altered. There are quite a few other ways to tell if a bat has been altered and knowing them is why we are a cut above your ordinary bat shavers. Umpires are now getting classes in a quite a few of these techniques but luckily we are a step ahead of them. This is not to say our shaved bats are to be used in sanctioned play but it gives an idea to the attention to detail we take when getting your bat ready for batting practice or that homerun derby you are getting in to.
Bat Rolling is a process that circumvents the natural break in process. A composite bat hits its peak performance at the 500 to 1000 hit range, This is because of the break down of the resin throughout the carbon weaves of the bat. Composite bats are made of several layers of carbon fiber, resin, and glue. When a bat comes from the manufacturer the resin and glue between the fibers are rigid and less pliable. As the resin breaks up the bat flexes more and increased distance is achieved. Bat rolling cuts out the break in period that is needed for a bat to achieve maximum distance, which is about 20-40 feet of extra distance. We perform bat rolling by going perpendicular first followed by parallel. We also offer a method of bat rolling that utilizes heat to further break up the resin this will break the entire length of the bat and increase the sweet spot to its fullest. Bat rolling is virtually undetectable when done correctly and is widely accepted around the softball community. With all that said; plain and simple bat rolling adds distance to the batted ball, with out a doubt!
