The frame was pretty straight forward to make. I used Aluminium Angle and "U" pieces from my locat DIY store. I found that the usual "cross-head" screws looked out of place, but I found some Pan Head on E-Bay which are closed in look-and-feel. I also sourced some Hex-Head bolts to hold the feet in place, again as these look morelike the originals. They are Metric but its not meant to be fine scale.

The small VGA display was also sourced from E-Bat. I think its meant for use in a car but it has VGA and two composite inputs (I guess for reversing camers) and runs off 12Volts. I was hoping to mill the "Trunions" that keep the frame and feet square, but I found that the K8200 just does not have the bed rigidity for real milling. I guess it tyhe next project will be a proper milling machine...

. oh and the stop lamp is a small red LED. The stop hooter is generated on the FPGA and fed into the Audio In on the VGA display.
