Heres the idea that sparked my build.
Construction is all pipe and pipe fittings with the exception of the table, which is a salvaged engine mount from an engine stand. The table is adjustable up and down and 360* in two planes, horizontally and vertically. I have dedicated 4 C clamps for assembly work and 2 vise quick clamps for flat work .
The next 4 pictures shows the degree of adjustment and the mounted clamps.
The next 3 pictures is an example of the set up for welding a small angle iron frame and the adjustments made for best joint access for welding.
