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 Ludlum turntable and the platter is driven by dental floss. This is very easy to do as the platter drive capstan is remote from the turntable and you can move it as far or near to the platter as practical.

Just take a length of unwaxed dental floss, join with a reef knot, put around the platter and the capstan and adjust motor speed as per a strobe platter.

The dental floss is terrific as it seems to last and last and because it is so thin and light it doesn't transfer any vibrations from the motor. I did use 2lb weight fishing line initially but sometimes I would forget to turn it off at night and it had parted by morning. I think it was the heat.

Great turntable. Silent as the grave. No rumble, nothing.

Concerning the turntable above it is not Ludlum it is a Lumley turntable.

Sorry for the typo.
