Here are some pics of tonights progess. Trying to keep all the round bar square was a pain in the butt and time consuming. And somehow I mis-calculated and came up 24ft short on the round bar I bought. I wont be able to get back on it until friday, so I wil get some more round bar then, and hopefully get everything welded up this weekend. This box is starting to get heavy also, but like I said....still a lot cheaper than aluminum.
