This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello List and Terry F In your post, Terry, you said: "ream out a couple existing tuning pin = holes with the same sized drill bit -" In engineering terms a "reamer" = is a "bit" with longitudinal slightly helical flutes. 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". Regards from a sun-drenched (but cold) Sussex Downland village.
