Thanks Bernie! It's a Tesla Coil... The toroid on the top is 12" in diameter to give you some perspective. 15 KV 60 MA Neon Sign Transformer for the power supply. Slowly, gathering parts and such to build another one. Bigger!
These are pics of one of the more unusual things that I have machined with my lil Chizou HQ400/3. Its a dual-cavity soap mold made from brass. The mold presses bars of soap out of a long extrusion. At the time I was toying around with a home CNC kit. I took up the backlash on the leadscrews with springs. I did a few jobs with it as a CNC but eventually returned it to its former conventional glory. The mold was mainly machined by positioning the x/y and plunging on the z with a ballnose (inside) or champher tool (outside the cavity).
