To sum it up, I started using custom made thumb inserts early this year. My pitches in the ball it was made from was 1/4 reverse and 0 lateral. After being made, the inside of the insert itself measures 1/4 reverse and 0 lateral just like the thumb hole of the ball it was made from, so every ball I have drilled now, the thumb hole pitches are drilled 0 and 0. The insert is then installed and the thumb hole measures 1/4 reverse and 0 lateral when finished.

No...Absolutely not....you will need to drill the pitches in the ball at 0 & 0.
I know what I am talking about because I am using custom made molds with the pitch in the molds 1/4 reverse and 0 lateral and drilling the thumb in ball 0 & 0 to get the thumb hole pitch to come out 1/4 reverse & 0 lateral. If I were to drill the same pitches in the ball as the pitches in the thumb mold, it would end up with a thumb hole of 1/2 reverse and 0 lateral.

If you center the mold in the cylinder, how could it POSSIBLY be anything other than 0 - 0????
Exactly!!!!!.....The same statement coming from Nick proves what I have been saying. Thanks for chiming in Nick.

It appears you must center the mold in the cylinder so that it is equal distance from the mold to the edge of the cylinder no matter where you measure it. In that case, yes the hole in the ball would be drilled to what the thumb pitch is supposed to be.
When Anne Marie Duggan makes my inserts, she simply inserts the mold into the cylinder as it came out of the ball so where the tip of the thumb is, isn't going to be in the center unless the pitches to begin with are 0-0. The tip of the thumb is going to be slanted to one side of the cylinder. It appears that the way you make your mold and the way she makes hers is different. When she inserts the mold in the cylinder, pours it, removes the mold, taps the insert from they cylinder and insert a pitch guage into the insert, it is the exact same as the thumb hole pitches in the ball, thus the hole in the ball is then drilled 0-0.

ROTFLMAO.....The feeling is mutual Nick.
Your illistration on the right is how my mold looks in the cylinder. Comes out with the pitches perfect every time.

The only problem with that method, is that if you have someone with 1/2" reverse or 11/16" like I had today, then there's no way that works.
Yeah, I agree if using a cylinder with a 1 1/4" inside diameter. My 1/4 reverse doesn't leave a lot but enough at the tip of the thumb area.
Anne Marie uses a 3/8" inside diameter cylinder for larger reverse pitches, but on a 11/16" reverse like you mention, I doubt that would work and your method for something like that is probably the only way to go.

Not disagreeing with you brickguy but I thought that regardless of how the slug is posistioned in the cylinder that the pitch for that slug would be whatever drill bit size you drilled in to the ball.
For example: If you had 1/4 reverse on the slug you made the mould from then you drilled 1/4 forward in to the ball you were drilling and put your mould in then you would have 1/4 forward on your thumb mould. The way you were explaining it you would come out with zero.
I'll try tomorrow and post results

That is how the mold came out of my ball and is how Duggan places my molds in the cylinder. Then she drills the hole in the ball 0-0 and the pitch is exactly the same as the pitch in the ball the mold was made from. Duggan doesn't intentionally put the mold in the cylinder in an angle. The way she makes the mold, it automatically enters the cylinder in an angle like that.
Now Nick does his like the middle drawing and in that case the hole in the ball must be drilled to the pitch you want the thumb to be.

I have always lined up my mould as close to straight as possible then pitched the outside hole of my ball to the pitch the bowler requires. Then put the mould in. (same way as Nick)

Without having the kit and being able to see it, I just don't understand how you get the top of mold to be dead center.
As Nick's picture shows, when the mold sits flat, it is actually angled. I don't see how the mold fits in the cylinder and is able to be centered and sit straight up and down.

My goal is to move from my current grip loc set up to a mold in all my equipment. I've already got the pitches drilled in the ball....so it sounds like when I make my insert I need to make sure the mold is centered in the cylinder.

What I love about the molded thumb inserts is that you can drill the hole in the ball, insert the insert and go bowl with no adjustments needed such as sanding, beveling, and whatever to get the thumb to fit.

Just for reference, there were no instructions from Vise as to what pitches you are to drill this at in my kit by the way.

It would seem to me that there should be a way to do both...drill 0,0 and drill with pitch.
I know personally, I've got one great feeling thumb hole that I absolutely hate the way it's pitched. Being able to mold it and drill the pitches into the ball would be the best of both worlds for that situation.
