Trike Recumbent Front frame

grabcad

Front part of trike. I try to use squared tubes as it is easier to weld it together on a welding master form. The tubes are laser cut such that the wheel base simply can be bend together in the final shape. Then welding seems are applied with MIG. Holes are placed far away from the pedals such that the torque has less influence on the stability of the frame and weight can be reduced. The wall thickness of the tube is 2 mm. One variant of material is 1.4301 grinded with K240 paper. I also will try it with aluminium.
