Been tinkering with an old Murray frame for several weeks, using as many salvageable parts as possible and a few items from the scrap pile.
After contemplating the bed build and doing the initial framing it occurred to me that the old medical records file shelf that has been gathering dust in the shop for 2 decades could have another purpose.
After adjusting the wood frame a bit, bingo! I have a 38" x 72" steel bed, complete with double wall sides, a front panel and a tailgate (one of the adjustable shelves) which can be located anywhere in the bed to handle lesser loads.
And it dumps!
Better half sez it's one of the best brain farts I've had.
Will put up a photo when it's completed.
