An old player vac motor helps to hold the hammer against the jig while holding the shank. I'm thinking of a jig which stradles the fence. I weigh samples across the set first to know about how much needs to be removed and again after filing. Tapering is done next to the degree the hammer will allow and/or amount needed to bring it to a desired SW range. Final SW graduation is done on the belt sander. >Some pinblocks get a bit too wide to drill from one side.

No problem with wandering bits. When I start the job, I drill two small index holes (5/64or3/32)through the plate into the block on each end. With the plate removed I mark the holes on heavy paper by first setting the edge of the paper along the front stretcher. Useing a straight-edge as a guide, I draw a line on the paper off the side and cut the paper on the line. Now I have a pattern of that corner (6-8" sq). Once it is fitted into the corner, I locate and punch the index holes. After the new block is fitted and secured with screws in place, I drill through my index holes into the block. With the block removed, I place the pattern on the block and place drill bits in the index holes to secure. I trace the pattern corners on the block on each end. I connect the front lines with a straight-edge. The band saw trims the excess and the jointer finishes the front. The block fits very snug and with a little hand filing, it is eased in place. whew. I make the block from a thicker stock so I can run the bottom through the planer to get nice clean holes underneath because the bit coming through makes a ragged edge on exitting and I can match the old block's height.
