I did the same with mine, but with 3/4"l x 1/4"d stainless nuts and bolts. I C-clamped the aluminum bar to the outside of the drum first, then bent it around the drum, clamping every 8 or 10 inches to get the aluminum formed. Trimmed the excess and squoze it into the inside of the drum. I drilled bolt-holes in the drum first then marked the aluminum for matching holes. After they were drilled, I had some problems with the holes lining up and had to re-drill a few. I would recommend you just clamp the aluminum strip inside the drum once you have it formed and trimmed and drill through both in one go.
My strip protrudes about 3/8" above the drum lip - if I do a future UDS I'd go 1/2" or 5/8"
I also used red hi-temp silicon to seal.
