Re: [CAD_CAM_EDM_DRO] Latest Design Created with my Sherline CNC

That's an excellent pattern, is that how it looked straight off the machine
or has it had some deburring? The edges look nice and clean. Also, I saw
your page a while back and was wondering how you inalyed the gold into your
rings. Are channels cut, then gold soft soldered as liquid into them and the
surface cleaned by removing a few fractions on the lathe? Will you use some
sort of mask to only anodise the inlay? I'm not some sneeky jewellers trying
to have off with your ways, just interested into how you do it.
