I've misplaced my Bill Taylor book and I forget.
The front of hole is X inches shorter than the joint?
Pitch of thumb....is this directly from the Bill Taylor charts.
ie 4 1/4 span = 0 therefore a 3 inch span is 5/8 of an inch forward???
Help professional drillers??
Doing some for some young children's christmas presents!
