Question about ring rollers

I am certain it could be done, but probably not cold. You would have significant thickness difference across the profile though. I would never consider this as the correct solution though. I would be cutting this from sheet. It would cheaper, faster and without material stress. Steve

shape or would it kink? Any tips are

I don't have any tools to cut it from sheet and make it look nice is the problem.

Somwhere this past summer this type of rolling was discussed on one of the metalworking forums, but darned if I can locate it. It had lots of photos of these operations.

I doubt that the HF roller has the type of dies to do it, it requires restraints on the flat sides while it is rolling. I don't think it would have the strength, for that matter.

Find a piece of 16" pipe, cut off a 1 1/4" slice, and beat it flat:-)

I'd consider this one for strength...

It is done all the time... it's called "rolling the hard way." Your problem is that the harborfreight crap probably won't have enough strength and/or rigidity to handle the job.

The concept, however, is sound......

That unit can't do it. Find a shop that has a #2 Buffalo. But that'll take a 20' piece rolled into a "spring" that then gets cut into rings that have to be flattened. One of my engineers used to do a LOT of roll forming and he doesn't envy the job. Cut it out of plate.
