OP: Question.

If you use a 21/32" bit to drill the barrel hole, How will you keep it centered in the 11/16" (22/32") drill bushing the TM jig has?

I think the reamer will follow where the original hole is drilled and if off center, even half of the space difference (1/64" or .0156") the barrel hole could also be off - even if using the jig.

I would be interested in what others have experienced and the best precautions that are available.
