Welded the end plates into the cross-beams...



The leg joint plates onto the main beams...



And the foot plates onto the legs...



Fairly confident in the welds, did a quick destruction test on scrap first, nice and hot concentrating on the thicker parts and washing into the 2mm tube. Joints are ground flush now. Casters will be added soon, to the side of the feet, the feet can be screwed down to lift it off the wheels.
