Ready Steady Eddy

[EddyCurrent]

Without a doubt the Z axis is the hardest part, progress so far.

I used a bandsaw to cut the profiles and then a static belt sander to clean up the profiles, internals cleaned using files. The motor mount consists of two 6mm plates which are glued and screwed together, the motor adjustment slot and slotted holes were cut using a drill, files, flapdisc.
The backplate where the ball screw is attached was 'milled' using my overhead pneumatic pin router and hand guiding the aluminium plate against a straight edge that was gradually moved across half a cutter width at a time.
The cutter was a standard cheap 2 flute 6mm dia. TCT router bit running at 9000 rpm and it worked great, only clogging if my depth of cut exceeded 0.5mm, I had a good jet of air blowing on it and just cutting dry.
