We may be missing the point here though. Is this perchance the same Dean
Hedin that has advertised custom grips in the gun rags for what, 40 years
now? If it is, then he should know better than me. A lot better.
So far I've tried that bit I mentioned in MDF only, and of course that
stuff tears uncontrollably. In fine grained walnut it shouldn't be quite
as big a problem though. I'd be willing to at least try it, with maybe
a .005" bit advance per complete pass. On my little machine probably
over half an hour per pass though. MCS is selling a little air grinder
rated at 70k rpms, I wonder how that might work mounted on the side of
the head on my micromill for something like that? Has anyone here
attempted something along those lines?
