It really wasn't that hard to do.
I used 4x4 3/16 inch thick square tube steel, 2 pieces of 6 inch wide flat stock, some 2 inch wide flat stock and a class 3 receiver tube from tractor supply company for the hitch. I am also brand new to welding, this was the first project I have done. Finished only with an angle grinder with cutoff wheels and some grinding discs and a few sandpaper discs. Paint is rattle can self etching primer and duplicolor low gloss black engine paint.
The angle and bevels were cut with the angle grinder & cutoff discs. the 4x4 tubing was cut in such a way as to slip together with the seams beveled to lay weld beads in, and welded beads around all the connections, then grind them down smooth.
Lot's of grinding was done
To cut the receiver tube hole I drilled holes in the 4 corners and used a sawzall to cut the square opening to size, slip the receiver tube in place, tack weld to keep it from moving. Then drill 4 holes from the backside, and plug weld the back of the receiver tube from inside until the 4 drilled holes were full. the rest was plain bead laying, with grinder and sandpaper discs to finish.
The d-ring tabs were done the exact same way. One funny note about the d-ring tabs, they are actually from my front bumper, they hung down, the maker of the bumper sells an approach roller option to put on that is supposed to make the bumper "roll" over obstacles that make contact with the bumper. I cut these off with a portaband,ground then down to a uniform shape since the cuts weren't perfect, then welded them onto my new rear bumper. This solved 2 problems, gave me the recovery tabs I wanted for the back, and got rid of these hideous things hangin from the front bumper for no good reason.
