Homebrew PCBs

I did my first CNC milled PWB today.  It came out great and far
exceeding my expectations.  The board is a little 3" x 2" solar panel
controller for solar battery charger.   The two layer board was designed
in DipTrace then converted to island milling G-Code by LineGrinder and
cut on my  Mach3 CNC converted Bridgeport mill.   The accuracy of the
milling was amazing.  I was able to drill .022" dia via holes and not
get any break-out  of the .040" dia via pads on the far side.

My bigest limitation is the spindle speed of the BP, at 6800 RPM and I
really need to get some sort of high speed spindle.

I postes some pictures on my Picasa web album:
