Homebrew PCBs

Hi John,

I guess I'll have to do that.  I've used cardboard baffles to keep brass
and aluminum dust/chips down, they normally just collect beside the mill
in the tray the mill sits in.  I got a STACK of dust (and some blew
around) from a PCB the size of a QUARTER!

What do you think of Phenolic board?  Can you use it?  MUCH cleaner, and
nicer on endmills!

I'm also thinking I might set up a small "hand vacuum" to keep THIS dust
down.
