I made this carry-all to fit the 3 point hitch on the tractor. It is designed to hold itself together so it wouldn’t be dependant on fasteners and hardware. The bottom is mounted to a crossbar. The front drops in front of the platform and behind the crossbar so it is captive. The 2 side braces are cut on compound dovetails so they will hold the whole thing together with out any fasteners and it is easy to disassemble to use the 3 point hitch for other equipment. The long narrow neck is required to allow the braces to enter and escape the compound dovetail lock.
It is made of fir and/or hemlock lumber and painted to protect from UV deterioration. It is 5 feet wide and bout 3.5 feet deep and high. I cut the dovetails for the braces on the table saw at a tilt of 9 degrees. Only one side can be cut on the table saw table. I free handed the other side with the saw set at 90 degrees. I suppose I could have just dovetailed one side, but both assure it will not come apart not matter how it gets abused.
I found the easiest way to cut the compound dovetail recess was with the sawzall, then clean the bottom up with a chisel. I started with a hand saw but with the 2x wood frame having both cross cut and rip cuts together, it didn’t work very well.
Edit: The compound dovetail keeps the side braces form coming out sideways as well as holding laterally along the brace.
One has to keep ones wits about themselves laying these cuts out. I was lucky to only make on upside down! Notice in the layout picture with the framing square, the layout lines are offset about a half inch to the inside. This is to allow for where the square will not allow the proper line to be drawn.
I forgot to mention I need to move the cross bar a ¼ inch to allow the front to drop down, then the dovetail on the bottom will tighten up and the carrier will be more stable. I took the picture when I first assembled it on the tractor hitch.
