Just bought the tube to do mine, borrowing a clarke 12ton hydraulic press off a mate to do the bends, I've been told to pack the tube with wet sand prior to bending as this should prevent creasing... not sure if it will work but nothing to lose. Using 50mm x 3mm wall for the main hoop and 38mm x 2.6mm for cross bar and rears supports.... good deal on ebay at the moment for 38mm tube think it was £20 delivered for 2M and discount if you order more.. ITEM# 160148565771
Rapid... I'll post a pic once done (if it looks ok
, if it looks crap I'll sit in the corner and sulk
)
