Here you go Tom. This is what I was talking about. I made these angle pieces that bolt on rather than just be butt welded on. The wall thickness is .020'' at the thin area. On the top view I don't have the 1/4'' tube milled yet,that's just one of the lattice pieces,also at that point there's two 5/32 angles back to back only one shown. Maybe by next week I'll have most of this area built I hope sooner.
