Hello, I am interested in finding out if someone can point me to a how to on some sheet metal work. I need to take a 10 inch piece of aluminum roll it into a ring large 4 foot ring. Easy enough I get get that done. But How do I set a 3 inch Flange to the inside edge of the ring. One sides flange will need to be complete with no relief cutts or tabs. I can go releif and tabs on the back just not the front. So that when I braze the ends I will have a flange capable of of holding in some plexi for a sign face and back. Hoping someone can point me somewhere.
The metal shop does not have the capacity that I think your looking for. Flanged rings are usually made with material that has a flange such as a metal angle and then rolled into a ring.
