"I don't carry any weight on the trailer, so I don't know why it bent, can you fix it?" was the question. When I looked into the back of it there was a ride on lawn mower, a dozen or so 16" truck tires on wheels and at least a dozen or more bundles of shingles stacked up in there. No weight there! Oh, by the way, the frame is all done in 2" x 3/16" angle.
The axle was built by taking a spindle and welding it to a piece of 2" channel (webs facing down) with some angle and mounting it with no springs. He still can't figure out how it bent. I did the repair with a brand new Dexter axle and springs and sent him on his way. Dave
