Quoted from NoQuarters:I pushed in the end of the shaft I marked "spins freely", It is hard to tell, but then, it seems there is resistance met if I lightly apply pressure to try and turn the cams. I am thinking perhaps when power is applied the yellow magnet pulls in and acts on the thin silver gear box and hidden gearing inside... Maybe things are ok. I'll find out when I eventually get the game set up all the way and power is applied to the ball lifter.
That small piece of the cam cog missing I am sure I can repair with an epoxy based filler.
The ball lift is probably OK. Your correct that when powered the 'armature' pulls in magnetically and rotates the shaft. Power off it moves out disengaging with the gears and rotates freely.
Regarding the piece of Bakelite needing repair the trick is to get another piece of Bakelite filed to the shape you want and epoxy to the side of the worn area. Make it as large as you need to get a strong grip, it will not get in the way.
You can have a third switch on this arrangement activated by a metal rod sticking out of the Bakelite cam yours seem not to have it on your game.
