The ring is being turned out of a piece of Aluminum 6061 tube. After I made all of my cuts to shape & size the ring, I parted it off from the aluminum tube.

What is the ring mounted on and how is it fixed in position on the lathe? It looks like a wood but how does the lathe tool not just rip it off?

do in stainless or titanium. Far better and its not toxic. It will be a bit more dif to machine but well worth it! Alum is way too soft and will not last a long time for a wed band!

It’s aluminum, yes. I’ve since learned that it is toxic to humans, although it apparently it does not bother some folks. I am planning on either anodizing this aluminum ring or turning one out of steel just to be safe.

What’s the material that you’re cutting? Look like alu but I hope, for your sake, you’re not going to make any banks out of Alu.

There is a way to make a more actuate/ rounder cutter.
Using the lathe, turn a bar of copper to the diameter you want. Then smear on some valve grinding compound. The grit gets imbedded in the copper. Rough the cutter out on your grinder as you did, then finish on the copper bar in the lathe. This will give you a finer cutting edge that’s less likely to dig in. Adding a rake at the top will help give you a stringier chip.

Yeah, I realized that my hand was in the way after I was done and it was already too late. Next time I’ll change the camera positioning

Unfortunaly the camera angle is ‘wrong’ The viewer can’t see what you are doing, love your toolgrinder
