I have a few questions, anyone willing to help?

It's more like right in the middle of my thumb, like if you bend your thumb and kinda flex it, it's right where the bone starts to stick out on the bottom of your thumb. My friend who is a licensed coach (he took the test a few months ago) told me i just need to build up a callus or something like that.

If the spot is here-


That's a indication that it could be-
1.Span Too Short or Too Long
2.Hole Needs More Bevel
3.Hole Too Big

Personally I believe if a ball is fitted properly, you shouldn't get any callouses or need to build up one.

I've got to agree with bowl1820. I've never seen anyone with a well drilled ball getting callouses on their thumb. No matter how many games they play.

yeah im with bowl1820 too cause i use to get a callius on my thumb awhile ago but i also never had properly dirlled balls for myself untill know and since i got my new balls i have not had 1 yet other then the 1 on the palm of my hand witch bowl1820 helped me out with when i did not know if i was doing soemthign wrong or right.

bowl1820 puts all the best stuff on here cause he know alot of placeson the internet or its beside him of everything that about bowling.

Bowl has the best diagrams, hands down. I use to get a callous at the base of my thumb, palm side. I didn't complain and my driller gave me heck for not saying anything when he saw it. Beveled the hole and no more callous.
Now I get one on the knuckle of my thumb. That's from me being a knuckle head and gripping the dang ball.
If your friend is really a certified coach and said you just need to get use to it, he forgot what he learned. The pic Bowl1820 put up looks just like the pic in the learning module for the bronze certification with the same reasons given and they strongly emphasize that callouses or any other kind of pain is NOT normal.

Here you go

First thing proper fit

I'm not sure what I find more impressive: all the links and diagrams or the fact you can remember where to find them all.

[striker12]

billf i think he has it all down on a paper so if he ever needs to find something he can find it in one of the sites but im thinking he has maby 10-20 sites on a paper thats my guess

He's got the bronze certification, and i showed it too him a few days ago, which it had time to heal. So he may not have realized how bad it was to start off with. How much would beveling my ball cost btw? I'm going to try to do it this sunday. I don't think the span is off or the thumb hole is too big, because the shop i went too according to my dad and everyone else i've spoken too (rather knowledgeable bowlers for the most part) have given high praise about the shop, and the ball is only like 2-3 months old, so i don't think my hand has changed too much in that time. The thumb hole in my ball is closer to a 90 degree angle though at the top of the hole, and that's what i'm thinking is causing the blisters and what not.

[Hampe]

If you take it to the same guy who drilled it I wouldn't think he'd charge you just to bevel the hole. It's not exactly a complicated procedure....and most pro shops I know will do small adjustments like that for free if you got the ball drilled there originally.

Thank you hampe, and to my understanding, beveling is rounding out the thumb hole at the top where it starts, is this correct? i'm not 100 % sure what it is.
