The Unistrut frame can be removed from the workbench but currently attached with a bolt at each corner to help prevent any movement. I’ve thought about attaching a bracket to the wall to pivot the LR out of the way or using pulleys to raise it up towards the ceiling. Unfortunately I don’t have a huge garage/workspace like some others on this forum. I was careful to pick the straightest pieces of unistrut I could find at HD.
Additionally pics show the cross members of the unistrut (total of 4), cable tie attachments (wood blocks cut to fit in the ends of the unistrut), and how the spoil board fits between the unistrut brackets.
