Two U-joints are better than four

I’m working on getting the human interfaces fabricated on Project Unfair and I just finished mocking up the column connection to the steering servo. Wilwood pedals are coming next, or possibly mounting the seat. The neat thing about this steering shaft is that my original design used 4 U-joints with the steering shaft under the motor mount, but Tim Christ at Coast Chassis Design (the gods of 10.5 racing over in Daytona Beach) convinced me to look into rotating the rack so the servo pointed above the motor mount.

So I did, and here’s the result. A very clean 2 U-joint steering mechanism. Good stuff. This photo is of the mockup with steel U-joints… we have ultra-cool aluminum versions from Borgeson on the way.
