Need some ideas on bending metal???

[CGCINC]

We used to roll wire or rod around pipes or tubes into coils and then cut it into rings.
If you drill a hole in the tube or pipe and put a 90 deg bend on the end of the rod it will hook so you can roll it around the tube or pipe. I would try a pipe or tube about 7" in dia as the wire or rod will swell after it is wound to a larger dia.

The wire torch holder on my welding cart shown here was rolled with the same method.

Yes! Undersized and let it relax to the full size I need!!! I like it!

Also, I found some Forged steel rings that are 8" buty I actually need about 8 3/16". Is Forged any different to weld than common steel?
