All things being equal.  </DIV> <DIV>    When I use the Multilam blocks capped with delignit, as you often do Ron, I find I need at least a .264 for a no. 2 pin. I hate tight pins</DIV> <DIV> It's Not only speed & cooling but wether the block is drilled on a stationary drill press or an in the piano set up.  I Recently drilled my first block in the piano & IMHO there is a greater possibility for errors as I have suggested in previous post because of the mobile- ness of the drill press & it's tendency to move & vibrate a bit. </DIV> <DIV>   I did some experimental drilling by hand in the same block using a 2 step method and truth be told the ones drilled by hand were a better fit than the ones drilled by the Drill press set up on the piano. </DIV> <DIV>    Admittedly one attempt is not a conclusion.  SO far the results are still good and no. 2 pins 2 1/2 inch Beine pins turn nicely in both holes but I will know more when the piano is strung sometime in the future. By the way it's a Steinway hexagrip Maple Block.....magic wood.Hmm.  Drilled at .257 at about 1300 ish rpm's with air. Not a chiller.</DIV> <DIV>  BTW I haven't been able to get my chiller to work well without blowing moisture even though it's run thru a filter.  I Don't' get it.  Suggestions chiller heads?</DIV> <DIV>  Regards</DIV> <DIV>   Dale</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>A .272" bit seems large for a Delignit block.
