I'm working through some final issues with my Genco Blondie... it's finally playable, and *almost* playing right. In trying to work through those last few little things, I managed to snap the shoulder bolt that holds the gear on the stepper. It's .185 diameter, and the shoulder is almost exactly 1/2 inch in length. The threaded part can be cut to length, and uses a #6 machine screw.
Anyone have one from a parts machine that they would be willing to part with?
In the interim, I machined a nylon insert and used a machine screw to hold it in. The gear is a little looser on the stepper than it should be, but it does seem to be working well enough for me to continue work on the machine.
