There = are two types: the Tapered Reamer and the Straight Reamer - in just the same way = there are Tapered Taps and Plug Taps in the "tap n' die" world. Are you saying = that you're using an ordinary drill bit to "ream" out the old pin block = holes? If so may I put in my English tuppence worth and suggest that the drill bit = have its outer-edge cutting corners rounded off. This way the bit is more likely = to follow the hole-bore instead of go off at a tangent. Just a thought from = my engineering days. The initial hole is, of course, drilled with a = standard sharpened "bit".</FONT></DIV> <DIV><FONT face=Arial size=2>Regards from a sun-drenched (but cold) = Sussex Downland village.</FONT></DIV> <DIV><FONT face=Arial size=2>Michael G = (UK)</FONT></DIV></BODY></HTML>
