I just spent a pretty penny having two bowling balls drilled. I have
been thinking of building a jig so I can drill my own balls. I know
how to build the jig, but I don't know how to position the ball to
drill it correctly. Anyone have any thoughts on this. I have a machine
shop in my backyard so the equipment is not a problem. Designing and
building the jig is not a problem I just don't know where to put the
holes in relation to the center of gravity or the pin placement.
Wait the two balls I bought came with drilling instructions. This
tells me where to put the holes for a specfic ball movement. As the
saying goes if all else fails read the instructions.
