So here are the changes:
1. For main body 200 x 5mm SHS at 1100 mm high (Can be any height more than 900mm and less than 1200).
2. Bottom plate reduced to 350mm x 350mm or any stock length around that size with 4 x M20 bolt holes on each side.
3. Top Plate 250mm x 250mm with 4 x M12 bolt holes and a 50mm hole in middle so I can add sand to tube body dampen vibrations if need be.
4. Adaptor plate 250mm x 250mm with with 4 x M12 bolt holes and a 12.7mm diameter hole in middle for mount adaptor
5. Top Gussets that don't require full welding across the length. Since the we are using a smaller diameter for main pipe, the gussets will assist in gaining back some stiffness.
6. Bottom Gussets that don't require full welding across the length. Since the we are using a smaller diameter for main pipe, the gussets will assist in gaining back some stiffness.
