Building the Motor mount

Mouter mount 1

This post shows the assembly process of the motor mount.
The first step was to weld the 4 nuts on the little flat surfaces. The nut will be hidden inside the tube since the bolt comes from the other side of the adaptor plate. I am impressed how well it worked out. Plenty of cleareance for the bolt on the transmission side.
The second step was to locate the rear plate and level the bottom bars.The bars are 1.25" square tubes and 0.086 in thick.
The last step was to triangulate the entire structure the same way as the FEM analysis to take all the loads.
The result is very nice and i'm very happy about it.
Since it's my first week welding I preferred to tac weld all the parts in place but leave the full weld to an experience welder. I wouldn't want a weld to break since all the loads go through these welds.
