Rumor has it that Joel Ewy may have mentioned these words:

Works for me. I have a smallish slab of 3/4" hardwood plywood that might
make a good base... ;-)

I'll have to check those out.

I wasn't looking to remove a thin layer - I was looking at cutting out
some/most of the board completely.
I have very good "fine motor control" (finger dexterity) for things like
typing & soldering, but asking me to actually *cut* something at 30K RPM is
just asking for trouble... ;-)
The (poor ascii) representation of the end of a CoCo cart:
___ / |||||||||||||||||||| \ ___
/ \ | |||||||||||||||||||| | / \
| | | | | |
| \___/ \___/ |
It's that stuff that I would find very difficult to "reproduce" by hand; if
a CNC could do it (speed isn't an issue here - only if it's strong enough
to fully go thru the PC board with a small routing/cutting bit) to cut out
the "ground wings" mechanically would be a massive plus.

I'll go have a look.
Thanks for the info!
