OK, so think of a cheap Harbor Freight compressor with the motor and piston sitting above the tank. Now think of me as I labor pulling this cheap but useable compressor around the back yard by its painful handle. Now imagine, if you will, all the welded motor mounts coming loose leaving me with a tank and a compressor in two separate bits.
Is it going to be a huge problem to spot weld the mounts back on the tank? Somehow the thinness of the tank metal makes me think it is but I don't know a hoot about welding.
