Dale questions: <BR>
<< Now I'm curious. If I used any thing smaller than .250 to drill no. one <BR>
pins in the buldoc blocks I'd be hatin life. Are you perhaps running the <BR>
drill speed slower or are you just stronger than Me.?Slower speed usually <BR>
nets a looser fit. I've been currently running drilll speeds of 1200 to 1400 <BR>
rpm.<< <BR>
<BR>
Well, I'm big but I'm weak (:?}}}<BR>
I have the rpm at 1000 rpm for the Steinway block. This slower speed <BR>
increases the chip retention in the flutes, so I usually drill half way, <BR>
lift the quill, then go all the way through. The Bolduc I used last seemed <BR>
to be about identical. <BR>
I think that the feed rate is more important than the rpm, though. As <BR>
you increase the feed, you increase the "wander", so a careful hand can <BR>
graduate the torque as you approach the top of the piano. I do this by using <BR>
a faster feed as I reach the upper part of the "C" range and then again as I <BR>
do the last octave or so. A niggling point perhaps, but I live with all of <BR>
my blocks, they become the pianos I also tune,so I really want them to be <BR>
comfortable and durable. <BR>
