I wonder whether going full triangular truss space frame might help? Would help give more strength at a similar weight at the cost of being (potentially much) more of a ball-ache to mitre and braze...
The tubing this one was made from is like 7mm od, 0.6mm wall thickness.
I think I need 2 1/2, 3 metres of tubing to make one rack and I just priced up 8mm od, 1mm wall and it’ll cost me more than just buying a full SQR set up :(
