My attempt at repairing a tank failure due to corrosion using epoxy and a machine screw. It seems to have worked... but for how long? The condition inside the tank is unknown, but today I do not have to buy a new compressor. This compressor worked well for many years but had one flaw, which was the inaccessible drain valve. I seldom drained it because of the difficulty so this resulted in excessive corrosion inside the tank.
