The local Sonic called and their dumpster gate fell apart. The gate wheel had worn completely down; allowing the bottom of the gate to drag the ground. I built a new frame from 1-5/8" galvanized fence tubing, and then I re-used the old hardware. I used my Imig 200 on this job. The frame is completely welded, the tube was cut on a 45, and notched with my harbor freight tube notch. I used a chop saw, and then I ground all of the cuts to remove the galvanize coating. After welding I touched all the welds up with cold galvanize spray.
This is the gate before I started working on it.
