Since I have no tubing bender with which to make the crank, and since budgetary constraints prohibit the purchase of one at this time, I had to go ahead and make up a jig to weld the crank together. Here it is with the parts attached. The microphone stand gave its life for this crank. Tomorrow I should be able to weld it up and mount it on the bike. That'll clear the bottleneck to fit the seat and steering, and then, it will roll.
