i got rid of my old shooting bench, it was plenty sturdy, but really heavy to pick up and move...I made this one using aluminum conduit, 2 sticks of 3/4” and one stick of 1” all are 10 feet long...I welded up a basic frame, 36” long, 24” at the back, and 30 inches at the front...I reused the old angled couplings (18Degree angle) and bolted it to the frame.my old legs were 1-1/2 aluminum conduit so I bushed the couplings down to 1” and screwed the legs in..adding a 1/2” plywood top finished it.its light, very sturdy, and the 3 legs make it very stable everywhere.. 
Ihave about 75.00 in it.i also haven’t figured out how to make the legs foldable without giving up the sturdiness...Mike
