Homebrew PCBs

Mike,

How wide is the blade you are using? I've used cnc to make pcbs, but 
it isn't as easy as it might seem: Noise, dust, frequent tool 
changes, uneven surfaces, etc. One thing I might be concerned about, 
especially if the blade is very thin, is bridging when soldering. The 
"traces: are varying widths, but the "spaces" are the width of the blade.

If the machine is capable of doing a second pass, you could try 
either dragging a conical bit through the previous cuts or cutting a 
second time with a very small offset.
