Here is how my good friend and techshop Jedi Danny Garcia made a cool steering wheel for a vintaqe style race car we are building at Techshop San Francisco
Step 1: Making the Metal Blank
Here we made the aluminum middle part of the steering wheel with a simple 2 d drawing and cut it out on the water jet. The only critical dimensions are the bolt holes and shaft diameter hole where it bolts to the steering column. A little careful measuring goes along way. It turned out to be a 9 minute cut file for the water jet.
