Step 3: Build The Wheels
Cut (2) 16" diameter circles out of plywood. I used some nice Baltic birch I found. I used my router to add the steampunk details. Drill holes for the flanges with the correct offset from the center as measured in the pedal shaft step. I used t-nuts to bolt the flanges on because I had them. I am sure other fastening methods would work. I also put black t-molding around the wheel. I got it from www.t-molding.com. I borrowed a slitting saw blade to cut the groove. They sell router bits to do it too.
Update: I thought I would update this step with some recent ideas. Commenter golddigger1559 had a great idea for some simple but high quality wheels. Golddigger1559 took an old set of smallish bicycle wheels and cut out the spokes. Screw the rim to a piece of plywood inside rim. You get a very smooth running wheel without a lot of work.
