A week in and the frame is looking pretty good. The vertical supports are in and the rails are ready to put on. Unfortunately, the central vertical pieces have splayed outwards significantly, making the rails non-collinear. Hopefully, as we add on the gussets and diagonal pieces we can coerce them into alignment. The treb is now taking up a good deal of room in the shop, so we are keeping it on a cart so we can roll it around. Sorry about the bad pics, I keep forgetting about them until I have to leave for class.
