One of those oh bother moments. Making the bathroom unit (finally) after cutting and sanding and jointing it all, had a dry fit up and it all looked good. It's a bit big and as you can see the garage is a bit crowded so had a board on the workmate to assemble it on. Went for it, got it all glued up and squared up yesterday, got back out there today and found this. It's not as noticeable from that angle but it turns out I had marked up the left and center uprights then cut the joints for the shelves on the left upright from the line down and glued them on to the center upright from the line up. Made for a very slight slope to the shelves. Had to pry them off and re-glue. Happily I have enough clamps for the job, plus I was able to get the batons glued on for attaching it to the wall. There's a ply board going into the large square opening which a mirror will attach to once it's up on the wall. Just need to get it oiled tomorrow.
