Callus on thumb bad?

There's nothing wrong with a "pop" noise.

Yes there's nothing wrong with the "pop" sound it's because your thumb is pulling a small vacuum in the hole. If you go to a slug with the vent slot or a drill a vent hole they will stop it.

Thanks everyone for your insight on this. The picture you posted is exactly where my callus is. It doesn't hurt, just doesn't look too good. My thumb is pretty much flat, but my thumbhole is a circle. I recently got refitted for 3 finger bowling, and the guy who drilled my ball did it this way. It felt so tight at first that he opened it up for me. However, now the sides feel perfect and doesn't hurt when I release, but the top/bottom part of my thumb doesn't even touch the ball. Do I have to ask them to make it oval? I assumed they'd know this just by looking/measuring my hand.

You might have to ask for them to do a oval, depends on the driller. Though he might not be able to do one, if he doesn't have the set up to do it.

Though you can get a Oval thumb insert, I use one. They just have to punch out the hole a little bigger and stick it in.

Being left handed the only thumb issues I get are skin wear on the right side (away from finger). My thumb is comfortable and I don't stick. This year I started wearing skin tape which basically prevents any thumb injuries or skin tear. I have huge knuckles and a flat thumb hense why i have friction on the same of my thumb.

That usually suggest a little too much left pitch.


A - Span Too Short
A - Excessive Reverse Pitch
B - Excessive Left Pitch
B - Hole Too Small

Thats where my thumb has had a problem until I went to the blue tape!! It WORKS great,,, and is slick enough to not stick in the delivery!! GREAT Stuff at any pro shop!!

Am I misunderstanding something? What does being left handed have to do with thumb issues? Or did you mean that as a way to show why the right side of your thumb is away from your finger? I do have a headache so it could all just be my brain melting.

Right handed or left handed the position on the hand is the same. Calluses appear in different places depending on what's happening in the thumbhole. Too much pitch one way or another, too little pitch, too large a hole, to small of one, span incorrect all affect what happens to the hand. To me it seems the simplest and most cost effective way of experimentation to find what works are thumb slugs. You can try out different pitches, sizes, etc, by having the old slug removed and a new one drilled, rather than trying to fill and redrill multiple times. I think everybody's thumbs are pretty much oval in shape, and if you can't get an ovaled thumbhole the next best thing to use is magic carpet in the back and plain old white tape in the front.
