Homebrew PCBs

BTW, I see that Enco has what appears to be the same thin air die
grinder that Harbor Freight Tools has. The difference for me is
that HFT is within a few minutes drive of me, and Enco is about 45
minutes away. So I can try the HFT's one and if it has too much
play I can return it easily.

I'm gonna have to replace my Dremel eventually, anyway, and I've
got a decent compressor already. So even if it isn't quite good
enough for a mill/engraver, I can still use it.

The hose on it is -very- flexible. I think it just blows the
exhaust out around the head, though. I'd prefer a more controlled
output so I could use it as a venturi vacuum to remove chips.
