More Chevrolet hand crank
Grooves were ground into the handle end of the crank blanks to allow for securing the spinner grip by crimping into the groove. The grooves were done before bending as it was easier to spin the straight shaft than to work with the bent shaft. Also for ease of set-up, it was decided not to drill for the drive pin until after bending.
The rods were bent in 2 stages after being heated with oxy-acetylene. First near the grip, then the other bend.
Final fabrication was to cut to length, cross drill for the drive rod and braze it into place. An alternate to the pin would have been a roll-pin driven into place. Minor adjustments to the pin length and length of shaft beyond the pins were made to fit the support bracket on the bumper and the crank pulley.
