Author Topic: Vise IT experiment. (Read 5844 times)

I've started using my vise IT system to alter pitches in my thumb slightly, as well as spans. I found that by drilling out a 1 1/4 slug with the additional or reduced pitches in the thumb. Depending on the size of your thumb this can be up to 1/4 in any direction. I now have 4 IT thumbs with different pitches depending on what I need. I then take that 1 1/4 slug and instal it into a 1 3/8 vise IT sleeve.

I personally feel that with more reverse pitch I can get more revs on the ball and lower my ball speed. With less reverse pitch I feel that I can throw the ball faster and change my rotation. It also allows me to throw my friends equipment that has an IT with different pitches than mine.

I'm excited to start doing this more often for my customers, and just wanted to share with the forum. If it is something you might be interested in, contact your local pro shop provider. If you live in Houston, come into our shop and let us give you a demonstration.

I hope this helps or contributes to your game everyone.

This is a cute idea, but is a little expensive and unnecessary. For the bowler who is interested in different rolls (tournament bowlers), most can simply adjust the tape in their thumbhole and make the adjustments necessary. If I am playing further in and want to get a bit more at the bottom, I take a piece of tape out or move the top piece down in the hole, which in effect gives me a touch of reverse. I do the opposite if I want to feather the ball up the outside. By making the thumbhole tighter it forces lighter grip pressure and less grab.

Not trying to rain on your parade, I just think as pro shops we should find ways to help educate customers on ways to become better bowlers without always trying to manipulate their grips or just drilling a new ball. I think making the game this complicated we could be doing a disservice to customers.

Just my $.02

I get what you're saying, bit I'm talking about a larger change than just a touch. For me personally, I have a 7/8 thumb hole. So i am able to change my span 3/16ths and my pitches up to a 1/4 different. This is a much larger change than possible with tape. My thumb pitches can range from 0- 1/2 reverse. This also helps me as a shop owner because I drill a lot of demo balls for customer use.

I would advise not doing this for customer for the fact that your promoting them to grab the ball. By going from forward or zero to reverse will cause them to have to grab the ball to hold onto it. This cause problems with their hand as well as it can effect their wrist and arm. I have seen it numerous time. That in the long run will cause problems for the customers. The ball should hold onto you and you not hold onto the ball. Remember there is a reason why most of the best in the world dont have reverse pitch.

This is more for people to be able to alter their pitches per their request, but already have ITs. It will help reduce cost of pitch changes for entire arsenal if their hands change. You are only thinking of the reverse. I personally used it to reduce my reverse pitch to allow me to not grab as much.

I believe that anything that is done for the possible improvement in other bowlers' game is a generous thing.

You should be complimented for your effort.

I have been doing this since they came out. Only difference is I start off with the 1 3/8 slug and drill directly into it with my pitch changes. You just have to be carefull when you move off center that you do not go thru the slug.

I do not really understand why you put a 1 1/4 slug into a 1 3/8 top ring, obviously, it will not fit and be loose.

Thanks whos left. I personally like to use reduced reverse pitch when my hand is tight from bowling a lot for comfort purposes as well as spare shooting. I just wanted to find a way to do this to the IT system in order to allow my customers be able to change all of their pitches permantly without the increased cost of plugging and reinstalling the ball ITs. I actually demo several high end balls throughout very often, and some of my customers have gotten these ITs with modified pitches to allow them to throw the demo balls witha closer feel to their actual ball. Only problem is how close their spans are to my demo balls.

Stan. That is what I do. But I hollow out the 1 3/8 thumb slug with a 1 1/4 hole and install a 1 1/4 slug that i work out before putting it into it for three reasons. 1, a lot of my customers do not like urathane slugs. 2, in order to install the two piece lock that goes the the bottom of the thumb slug/IT properly, the hole has to be drilled relatively straight down to hit the safety stopper. I tried doing the pitch changes directly into a 1 3/8 slug/thumb IT and found that it was less secure this way. And also ran the risk of drilling through the side of the slug when changing pitches very dramatically. 3, I use the work out ball that came with my IT kit, and my new mill press to drill out 1 1/4 slugs with perfect ovals to fit my customers before I install them into a 1 3/8 slug/ thumb IT to make sure it is a perfect fit for them.

So, basically you are using a 1 3/8 slug with the slug-IT attached. Then then put the 1 3/8 slug into the IT ball jig and drill using a 1 1/4 drill untill you hit the stopper. Then you insert the bottom filler into the IT ball drill and insert a normal 1 1/4 slug into it to drill out to the proper thumb size. I guess at this time, drill your oval. Then you take the 1 1/4 slug and insert it into the 1 3/8 IT slug. I assume you are using the vent holes to line up your oval to the 1 3/8 slug. At this point, you just insert your 1 3/8 slug into the ball and trim.

Depending on how sharp your drills are, how hard is it to insert the 1 1/4 slug into the 1 3/8 ?

Yes. That's exactly what I do. I use the angle adjuster on the fitter to make ovals at the right angle. My bits are practically new. So the fit is great. Some 1 3/8 slugs end up fitting a little tight. Then I just use my disk sander to open up slightly. Then it slides in and out smoothly and allows for perfect fit.

Stan, stop by my shops Facebook page to see pics of the first three I did to test. Used different colors and pitches to make easier to visually see. Not sure how easy it is to recognize in the pic though

Took a look at your facebook page and I really like the color combo you used. Nice work.

I may have to give it a try.

DeadWood Pro Shop · « **Reply #12 on:** January 21, 2012, 06:49:28 PM »

Thank you sir. I do 2 color combos per customer preference , but I like the funky combos. Haha
Stay tuned for more updates as we come across them.

If this helps one person, then it was worth posting online.
