Details, details,details --- Seems the big stuff goes fast. It's all the little sh*t that eats yer lunch.
At least both of the deck mounting plates are done. The gray square tube will form the innermost deck support.
4 - 9/16" bolts should hold this sucker in place. At least this way, If I get rear ended (or back into a boulder), I can remove the deck fairly easily. The 3 in a triangle are bolted through 2 - 1/4" plates and the other is threaded in. 3/16th" x 3-1/2" x 2" C-channel will weld where the beveled edges are.
And here is what I came up with for supporting the deck when down. 2 sections of 1" blackpipe with 5/8" all-thread run up through 2 nuts that are welded in place inside the tube. Here it is partially extended...
...and partially closed. They each have 16" of travel so I should be able to adapt to most terrain. The "shiny" spots are where the bolts are welded in. Each will hang from a swivel mount and have a 4" x 5" foot plate on bottom.
Still waiting on my main frame crossmember.
