Have anyone replace VPI SSM belt with string?

Most heavy platter tables like Verdier or Micro Seiki use silk or string to drive the platter and reason is obvious. VPI SSM or HRX both have heavy fly wheel that motor has to drive. I can hear my VPI SSM belt noise when it is not perfectly clean and will wobble and shudder especially running at 45RPM. This is more obvious on the two small belts driving the flywheel which much more work than the long belt driving the platter.

Has anyone tried using string or dental floss to replace the belts on VPI tables? I know for SSM or HRX, making two identical length strings for the motors will be extremely difficult and that means different load for each motor. But is this idea feasible at all? Are there any downside to the string?

I have a VPI HMW19 and am in the process of building a DIY SAMA. I want to have it out board of the plinth/frame so it can be really massive. It seems to me that if the pulleys are the same size as stock then no matter how long the string is, the speed will be correct.
Am I correct?

Also, my friend that has a beautiful Teres, uses silk thread that a very nice lady at a fabric store sold him.He swears by it.

Just did a experiment with some ordinary poly-cotton thread on the HMW 19. I got it working which was the main thing,but it is a hair slow (checked with a strobe and by ear).
I imagine some better thread and with more adjustment I can make it right. Therefore outboard here I come!
