Many have noted the stair stepping on my sequoia. The top is clearly out of square. Today I set to work trying to square it up and it is not going well. I put a tie-down strap diagonally across the top to pull it back into shape. Before I did anything with that, I turned it upside down and found the bottom at least as bad. That part is only held in by he axles for the wheens so I pulled them out and this is what I found:
It is not loose allowing it to go wonky. It was put together that way! Some of the nails missed the mark and split the stringer they are fastened to. Rather than pull against the fasteners, I knocked the boards off and am waiting for glue to dry where I repaired the stringers before I reinstall the slats.
I turned the cart back upright, preparing to fasten the boards with additional nails to hold the top square. Incidentally, it took more tension than I expected to pull the top square.
Looking carefully I noticed that pulling it square opened small gaps between the boards in the top.
If you have a Sequoia, please confirm to me that the boards on the top but against each other. I think I'm going to have to pop them off too in order to close the gaps.
The gaps are nominally 1/16" (~1.5 mm.)
