Welp fellas, I pulled the trigger on an Oil Can delay unit. Should be here Friday. Seller says it worked and there was no ticking (an indication of a scratched dielectric plate--an irreplaceable part). I bought some of that fancy oil, too, just in case. Any one have one of these, any tips or tricks or things to inspect upon receiving? I know the disc and the heads are irreplaceable and the specifics of their manufacture is lost to history, so I will be very careful around those. Any tips on opening and sealing closed the oil can? I am almost afraid of this thing, because it is so precious. Also, I was thinking of adding some sort of speed control to the motor, perhaps PWM or some such thing, I will have to look into it. Or if any one has any ideas, that would be cool. I am pretty sure it is a shade-pole type induction motor, but I am not sure. The motor is not on any of the schematics I've seen.
