>When drilling tuning pin holes in new block in a full plate with no plate >bushings, how best to center pin? I just chuck a 3/8" bit in a drill and bump it straight down into the webbing holes. it leaves a dimple in the pinblock that guides the "C" bit into the middle of the hole, (I use 1/0 pins). Quick, easy, cheap, and dead accurate. Regards, Ed Foote RPT
