Cont 2 Turntable Speed

[jturner0305]

Hi again from Florida! My restoration on the Continental 2 is going well. I do have a speed issue with the rpm. Currently sits at 46.7 RPM, which doesn't sound horrible, but on some records, it does. I have checked the bushings and the motor shaft. With the Automix feature, it is bumping up to the top of the shaft, which has a step bushing giving it the "45" speed (actually 46.7). On the lower, it spins slower, 33.8. 

Any thoughts?

Hi JT,
It's the other way round, isn't it - the 33rpm is at the top (smaller diameter) part of the motor shaft? Can you post a picture of the motor shaft, you can use postimages to do that. 46.7rpm is too fast, how are you measuring it?

I'm using the whirlometer application on my iPhone. It appears to be very accurate. The top of the shaft is supposed to be 45 rpm. Lower is 33.

Strangely, I remember these having the smaller diameter at the top of the shaft - maybe I'm confusing them with later models or Rock-olas?? Anyway, it's a spring on the shaft which will have to be reduced slightly in size either by replacement or filing down the existing one.

If you have a micrometer or a digital caliper, you can accurately measure the diameter and reduce it by the ratio 45/46.7. You can carefully file the existing spring by removing the motor and running it but take great care to avoid getting filings in the bushing. You'll probably be OK with the 33.3 rpm section if you do intend to use it.

Sounds like a plan. Many thanks. Stay tuned for update.
