So here's the one pic for today. No progress on the tank, but damn happy to get the lumber I've been holding off on. Got 65 more 2x4s and 5 sheets of ply. The ply is behind the particle board. Decided I'm going 1/2" ply on the outside and 3/4" ply on the inside. That will bring my wall thickness to 4" of nearly solid wood. Glue between each 2x4 that's butted up against each other, and more adhessive between the ply and the flat face of the 2x4s. This thing will be rock solid. On top of that I will still need some top and bottom braces. Then I can start sealing. Going to try and get the skeleton as far as possible saturday. That's going to be my all day long work day on the tank. Sunday and monday I have training so that's pretty much a no-go. I'll update progress on saturday when I'm taking breaks. See if I can't add another 10' at least. That will leave 4' and the right wall, plus plywooding it. Oh and still need to get another 5 lbs of screws. So far screw weight is 6 lbs and counting.
