Well I decided to see if I could get the issue sorted out, so that the gears would not slip when in the normal direction of rotation. As the issue is with the selector pin, I removed the gearbox and motor assembly from the mill and took it to my other workshop, where my lathe lives.
To make life easier, I welded up a quick and dirty stand:
With the selector lever removed and disassembled, the wear on the pin and the bore was evident:
I turned up a new pin, so that it was a close fit inside the bore. I also increased the size of the head, as the holes the pin engages were also worn:
Once I was happy with the fit, I put it all back together and wired the motor up. Flicked the switch and the gears stay engaged. A much simpler fix than I had imagined!
Sorry for the poor quality pics. The lighting was bad and the flash just washed out the pics. Pity, as I was really happy with the finish on the pin. Also, the battery died, so no pic of the freshly polished brass handles either
