Okay what is the mechanical/technical advantage of having the stands at that 10-12 degree angle?
When you tighten up the clamps, the motor is close to being vertical. This makes it easier to work on and looks better than having the motor kicked out on an angle. It also makes it easier to run the larger motors with their lower end dipped in a tub of water. On my storage racks for donor motors, the cross piece is straight as most of them are missing the clamps anyway.
