Replace VPI TNT rubber belt with nylon thread

Thanks Don, but I'm not sure I can actually remove my capstan from my motor. I've tried before and I really think it is epoxied on. My VPI motor is very old.

I'm afraid to do this properly I would have to buy a second motor, and I really am quite happy with the silk thread.

The old VPI pulleys were pressed fit onto the shaft. If you put your motor into a freezer, the metal motor shaft will shrink more than the delrin pulley, therefore, easing up the tension.

Ah... cryo treatment. Another great tweak!

Doug, what issues did you have with string drive silk thread and dental floss. Did you spend much time with either of those or was it quickly obvious vs mylar tape?

Thanks, TD

Years ago when the belt on my Aries broke I replaced it a double strand of 4 lbs test fishing line. I had to change the SDS settings but it runs like a champ. I have a super heavy clamp so I do give it a little push at startup.

Too lazy to try anything else...
