PCB Milling updates

Good news... I received my PCB milling cutters yesterday evening and finished my trial cuts last night. Results are very good... happy with the cutters... and the price... Got them from Andrew Abken who's selling it on eBay for USD6/pc...

The cutters as delivered by Andrew. Perfect packaging for the trip of half way across the globe.

Photo of the sample cut made. Isolation gap is approximately 0.2mm. Cut using the Sherline Mill at 6500rpm @ 8ipm. No burrs and very consistent cut. Worth every cent paid...

Here the PCB photo as captured from Cadsoft Eagle (http://cadsoft.de/)
The Gcode for the isolation milling was generated using PCB-GCode script available at Cadsoft website and discussed here http://groups.yahoo.com/group/pcb-gcode/

BTW, the PCB is a functional PCB of a VHF foxhunt transmitter...
