It should be at the correct speed in a few seconds. Do you have the right amount of bearing grease in the flywheel bearing well ? as well as in the platter bearing ? Too much grease can cause them to run slow, all you need is a very small dap at the very end of each shaft, right on the ball bearing, prior to slipping the platter and the flywheel on.

I would think that oil would run out of the bearings due to gravity leaving the thrust plate high and dry, i have only ever used white lithium grease in my many many VPI based tables and have never had any trouble. Viper Lube Best of luck Peter |
The Dual motor Flywheel drive station for sure use a inverted bearing, which should be greased ad I described above, too much grease will cause it to bind up. I use the SDS on all my belt drive tables along with the Dual motor drive station and it is very stable and up top speed in a few seconds, speed is checked with the Southerland time line. If your plater is older and do use a well bearing then indeed you should use a thin viscosity oil on the platter bearing. As far as belt slippage, possible, I use 4 belts from the Dual drive station to the platter so that to me has never been an issue. Groovemaster Good Listening Peter |
I suppose that is a possibility, but a motor is a pretty simple mechanical devise, and of the many many of them i have had come through here I have never had any issues with the motors. Did you buy a new Dual Drive Station ? How are you checking the speed ? Are you using a SDS ? If you table ran at speed before you added the dual drive station then the main platter bearing is not the issue. The only issues I have had is if too much grease is added to the inverted bearings they can bind up causing the speed to vary. I don't know where you are located but is your close to us here in San Diego your more than welcome to bring it by the shop and I can take a look at it for you. Good Listening Peter |
Your actual SDS setting is not that relevant it is what ever it is to run at the correct speed, that the setting is not exactly 60Hz is caused by the product the small deviations in all the mechanical interfaces from the motor to the platter. My SDS on one of my tables here in the showroom is set at 59.29. What belts are you using from the motors to the flywheel ? maybe that is where the culprit is, I use these AS568A-155 Buna N 70 Only use one o ring per motor to the flywheel, then use 4 of the long ones from the flywheel to the platter if that is possible for you. The long ones are not readily available - we make them here from the same type material but thinner and available in 100M spools. If you need some let me know what length and I can make them for you.
