My clothes dryer's drum is made of aluminum rolled into a cylinder and welded together along a single seam. The weld has developed a crack approximately 1" long, and is opened by about 1/8th of an inch.
The crack flexes on every rotation as it passes by a roller. I've attempted fixing it with standard J-B Weld. After sanding, cleaning, and applying a moderate layer of JB Weld to both sides I allowed it to cure 24 hours, but the crack reappeared while doing the first load of laundry.
What product(s) can I use to mend the crack and prevent it from re-opening, wihtout it failing in the heat of the dryer, or leaving residue on clothes? I've thought of trying to combine an epoxy as well as a strap of reinforcing tape on the outside of the drum, but don't know what specific products to try.
