1928 Victor Induction Disc Motor & 1931 Dajos Bela Tango Blues - O Sole Mio Berlin Victrola

There is a bottle of slick 50 in the background. Are you using that for lube?

[sanfranphono]

Yep, I guess even if the oil goes away, the silicone will continue lubing. No idea if this is working. Do you have an opinion?

[chilldude2007]

I think it's a brilliant idea. Probably 10 times better than regular oil. I'm going to try some myself !

[sanfranphono]

Yeah I hope, provided that the stuff does not gum up.

I had bad experience with drying greases and evaporating oils, so I use slick for oil and black graphite-moly for grease on the assumption that even when the stuff evaporates, there are still enough solid lubricants left. Let me know what you think.

Thanks for interesting clip. My Credenza rotates stable enough but it sometimes rumbles. Perhaps former owner attempted to flatten the rotator???

[sanfranphono]

Don't know exactly what you mean by rumble, but that sounds like something from the govenor, or most likely the gears.

If you watch the disc from its edge, you see if it is not running quite true.

What I would do is take out the gov and the gears, incl bushings, clean everything, and the slightly play around with the position of gov and gear to find the quietest meshing point for the two (you see me do that at the end starting at 3:35.)

Excellent video and very educational. I find the comments very helpful.

Yeah, if you have ever tried to straighten out a bent disc, you will know the problems. Even if you get it straight so that it doesn't touch any more, the motor will have a swelling hum with each rotation.

Cheers, more to come ...
