I've been trying to find the 4 uprights needed for the next rack ,found 3 round upright poles to use but have to use one RHS upright ,all I could find was 3 scrap bits of RHS that needed welding together to make a 5 foot length.
The green parts of the 5 foot Upright is 1/4 inch thick and the blue part of the RHS is 1/8 of an inch thick, not sure if I should put the green part down on the ground or the blue part of the pole on the ground , I guess it would depend how strong the welds are to which end of the pole will be stronger ,I'll probably go with the green end on the ground.
Lucky I have an old train line the clamp the metal to for welding otherwise it would distort too much to use.
