Friday Progress Report
Good Friday afternoon my fellow ADers. With the filler neck and spare tire hoist tasks complete, I turned my attention to the Rear Bumper. As I mentioned in a previous post, I had a "lightbulb moment" where the HOW to attach became clear. First, I positioned the bumper (square) on the workbench. Then, I sketched what the brackets needed to look like- right on the bench. Using 3/16" X 2" flat stock, I fabricated the brackets. I "kerfed" the bend lines with the band saw, to make the bends doable by hand, and it kept the bends crisp. I will weld-in all the kerfs when I blow it all apart for welding.

Next, I assembled the pair of brackets to the bumper, and then the rear bumper "filler panel" over the nuts holding the brackets. This gave me a subassembly to clamp to the rear bed crossmember. Then I cut some 1-1/2" X 3' box-tubing sections, followed by "tabs" of 3/16" X 2" flat stock to attach to the frame, using the 1/2" bolts that hold the hitch. I added a second tab (holes yet to be drilled in frame) for two points of contact. DRIVERS SIDE

REAR BUMPER, INSTALLED

A very productive week in the shop. I am pleased with the bumper mounting. I have some "energy absorbing" features, and the bumper is held to the frame with 3, 1/2" Grade 8 bolts at each side. I will have my local machine shop cut the 2-1/4" square hitch-access hole out of the bumper rather than doing it by hand.
