Anyone have problems with a driller either not being able to (or unconciously unwilling to) exactly duplicate the drilling of another ball?

My main driller is fantastic, and I am happy with 90% or better of what he does for me on the first try. And if a ball does need adjusting, he's very good at fixing it. But... he doesn't carry any used balls for sale, and while I buy mostly brand new, occasionally I'll see a used ball in another shop (at another bowling alley) and snap it up.  

I could take the ball back to my favorite driller, and he would drill it for me, but I'm usually anxious to use the ball right away, and I don't really want to advertise to him that I have bought a ball from someone else even if he doesn;t carry that version of it (i.e. used).

Unfortunately, whenever I do that (buy a used ball and have it drilled up by somneone else) I am almost always disappointed and frustrated.  I ask them to match another ball that I have with me that fits perfectly, and at first....it seems like they did that. But after awhile, I begin to notice that I am coming out of the ball too soon for one reason or another, usually cause they did NOT duplicate exactly the thumb in terms of size, pitch, amount of beveling, and even the shape of the thumbhole. The exact discrepancy doesn't matter. What does is the fact that they cannot seem to comprehend or execute the request that they MATCH the other ball.  

Why is that so hard?

In the end.... I frequently end up back at my main driller begging for mercy and asking him to fix the mis-drilled ball.

I personally have only had that done once and that was when my uncle ran his own pro shop.. No one in my area does it.

I'm not saying anyone is right or wrong here but when u tell most driller to open the thumb hole up a little the first thing they do is grab a bevel sander. if you know what you want and they way you want it done (which it sounds like you do) you need to specifically say that to him and what areas you want opened up. because just say you want it opened up a lil could make one think the whole thumb hole. not just the bottom or a side.

Years ago, drillers would put yellow wax pencil on your thumb, and work out the "rub areas", where yellow wax was left in the hole...Haven't seen that done anywhere, since the early-1980s.
