From there, I used a sander to finish shaping the pedals and round the edges. I then drilled out a number of holes (as laid out in the drawing) to save weight.
I'll use the pedal swingarms to line up the pedals with the brackets, then attach the brackets and pedals with JB Weld. I may add grip tape if I feel it'll be beneficial. I have enough material to do two sets of pedals, but I haven't decided if I'll install them both or only the pilot's side. The passenger/"copilot" won't have brakes, so pedals would really be superfluous. Once I build my brake cylinder bracket, and have my seats installed, I'll attach the pedals to (and most likely relocate) the swingarms with PVC pipe and a screw (again a la Mark Langford).
