Default Re: Crank hole cover rivet

The crank hole rivet was originally a tube rivet. Originally installed on the back side of the shell was a small flat washer and a small lock washer. It is the lock washer that provided the proper tension after the rivet end was set. Use light taps and check after each tap to achieve the right tension.

No special tools are necessary. Use a proper sized drill to drill a divit into a block of steel or similar and hold in a vice. Use a round, pointed chisel to spread the rivet end and finish with a flat drift. Use tape on the rivet head during this process if you do not want to mar the finish.
