i) Validate the design properly

ii) Take printout of the different components in flex at 1:1 ratio of different parts like RHO, RRH, and BASE & SIM

iii) Make proper bending of the components and avoid cuttings to avoid more welding. Try to make longer parts continuous by doing bending rather than cutting and welding, this will help to reduce weight and enhance strength

iv) Do an initial tack or spot weld of the whole structure, this would prevent mistakes and give you a chance to recover if you do any mistake during fabrication
