need Teres platter diameter

directdriver · 14th July 2009, 10:13 PM

I am in the process of machining a pulley for my friend's Teres turntable (he's too busy and not have the turntable with him at the time) and I need the diameter of the platter. This is the earliest version of the Teres project. Any help is appreciated. Thanks.

I measure mine at 12" 15/64, using a 24" Starrett rule w/ 64ths scale. The grads are so fine, it might round down a bit to 14/64ths, but using the 32nds scale, it looks a bit proud of that lower mark.

The platter measured is the early frosted one, with a stick-on strobe.

Hope that helps.

Here is a drawing of a pulley design that works well with a Teres Platter. I can be made for string or tape. This is from a group buy back in 2007 by Algar Emi.

Thanks for all the help. I was searching for a suitable direct-drive turntable as the motor to drive my friend's Teres platter.

Would this design work with a platter like this one driven by a mkelly/algar drive system?

Also, does anyone have a pulley from the GB to sell?

On a similar note, where would one find the spindle or bearing that the pulley mounts to ?

I currently own a Teres and am redesigning the plinth. I'd like to add an idler pulley / tensioner in addition to the drive pulley mounted on the motor pod.

If I had a suitable pulley, what kind of bearing / spindle would I mount it to (on the plinth)?

Are you trying to implement something like the Artemis SA1 turntable designed by Frank Schroder?

Yes, I'd like to try something similar but haven't found a source for the parts yet.

Something like the tension arm from an old reel to reel would be absolutely perfect for your application.

I don't want to hijack this thread too much.....

Thanks for your suggestion regarding the tension arm from a reel-to-reel, Unfortunately, I don't have an old reel-to-reel deck (or old VCR, etc.) so I'm looking for an alternative, ready-to-purchase parts source. In addition, I'd like the pulley and tensioner to be non-compliant (no rubber and / or springs).

Thanks again.
