Probably not all that good a thing you describe below. I ran into that one quite a ways back as well, and I think most anyone whose done any pinblock drilling has as well. I always bypassed the problem by using pin bushings that were not pre-drilled. A dab of glue between the pinblock and the bushings keeps them tight so I dont run into the spinning bushing syndrom. I'm not really sure whether its a big thing really... bushings get slightly crushed pretty easily.
