Redrilling a bowling ball?

Question

Im looking at a bowlling ball from ebay, but its pre-drilled and im not sure if the holes are big enough to fit my fingers, is there anyway to make the holes bigger if the holes are not big enough?

Answer 1

your best bet would be to take it to the pro shop where you bowl or which ever one you choose. They will most likely  plug the holes, measure your hand and re drill the ball.  

Answer 2

All you have to do is bring it in to your local pro shop (most likely inside a bowling alley near you).  They can plug up the fingers and thumb, and then re-drill it to your own specs.

Now if they are REALLY good, you could get away with only plugging either the thumb or fingers (depending on how the ball is drilled before), and just make the other hole(s) bigger.  This would help you save a little money at least.
