Thanks. Hi Avery, If the bushings are anything like Kawai's, they're pre-drilled or dimpled, not solid. In production this is an expedient to make the subsequent drilling bit follow the dimpled area instead of wandering or "skating". I rather like this method, since domestic bushings will often snag at the moment of drill-through and start to spin. I don't think this should cause any undue concerns with an existing block, all other things considered. With either method, your angle is either right or not. Besides, once you get to the existing holes, the bit is going to follow anyway -- the bushing just follows the program. About the height, any guesses would be wrong, based on my track record! Those same bad guesses have taught me to order a quantity of ALL of them. HINT! <g> Jim Harvey Jim Harvey harvey@greenwood.net Greenwood (n): the largest city in South Carolina WITHOUT an Interstate
