Assuming you are just making a pair or a few more, make a layout table
using particle board or MDF (not plywood) set on 2x4's and sawhorses. Do
the design full size, lay the steel in place, use 8d finishing nails to
hold things loosely in place. Tack weld soldily, remove from the
fixture, alternate welds on both sides to minimize warpage. You can use
a 4" hole saw to make holes at the weld points if you want better access
to the welds.
