I just made a 4 inch band strap for hanging a temporary stove pipe. Took a piece of sheet metal, rolled it into a round shape, and put a 1 inch bend in each end, in order to screw the two ends together.franco b wrote:What's wrong with cutting a strip of sheet metal to the dimensions you need? Bend up the ends to take one or two nuts and bolts with a small piece of sheet metal to slip inside the area not covered under the bolts. Should still secure with sheet metal screws though. You could cut the strip from a piece of 7 inch smoke pipe; after bending up the ends for bolts it would leave a 1 inch gap under the bolts to cover with a small piece of the same material.
