At last: frame welding
night. Our welding jig/table is David's 1/2" thick steel bench.
Located in the middle of the shop for three-sided access it is 4'
wide and 8' long. Using an 8' long piece of aluminum, a square and
a tape for locating, pieces of steel were tack-welded to the table
top.Welding the frame went faster than expected. In four hours the
tree of us had one frame ready to sit in and the other two bottom
sections welded up. Care needs to taken not to weld all on one side
of the frame or it will warp. Tack things up before finish welding.
