Modified my Bench, added a third layer of 3/4" plywood ( screwed and glued to bottom ). Moved left side leg back closer to the middle. Tack Welded the legs to the screw in mounts. Made mistake of using electrical conduit pipe with non-taper threads for ease of use but they wobbled. Should of used pipe threads.
Bench isn't light now but it is solid as a rock. Also knocked end caps off legs and just left bare pipe ends which bite into the ground better.
