I drill pinblocks outside of the piano, on a Jet floor-standing drill press 
turning at 870 RPM. I have compressed air blowing on the bit. I do a test patch 
on each panel to get my feed speed right. My surprise at the higher torque 
figures obtained by others is making me wonder about the runout of the chuck or 
spindle. I'll look into it. The chuck is the heavy 1/2" one that came with the 
press. I suppose it's replaceable. I don't know about adjustments for the 
spindle. 

It's been my impression that maple blocks are softer than they used to be, 
but maybe it's my equipment! I'll drill some test holes in the old block along 
with the next new block I drill.
