Background:
Wife bought me a Gil-Mac for Christmas, so I've been doing my own work for a couple weeks now (Santa showed up early).
Situation:
I've purchased a few used balls that have thumb slugs. One ball had no pitch in the slug itself, but had 1/4 reverse in the thumbhole. The next ball had 3/8 reverse in both the slug itself as well as the thumb hole.
Question:
How can you determine if the original hole drilled to place the slug was drilled "neutral" or with pitches? I'm getting pretty good with the machine, but I'm not sure where to start when attempting to drill out an old slug.

Most drillers drill the hole for the slug at the same pitches the thumb hole will be drilled. However, if the customer later wants to try a different pitch combination, you drill out the old slug (using the same pitches it was installed at), insert a new slug, then drill the hole at the new pitches. That may have been why you had a ball with the slug and hole at different pitches. I'd set the pitches at the same as the hole and drill it out. If the slug was at different pitches, some of the slug will be left toward the bottom of the hole. Just leave that in place and drive the new slug in. -- JohnP
