Upgrade for Vpi aries table

Edle,
The noise you are referring to is caused by a dirty, or worn out belt. clean it with wipes. Put the newly cleaned belt in a plastic pouch with corn starch or foot powder. Shake the pouch and take belt out and re-install. This should be done at least every 3 months. However if belt belt in already yellowish in color, it is time to replace. The newer nitrile (black) belts are much better but needs to be cleaned too.

I'll leave it to others to note the virtues of the various upgrade paths on the Aries, but one unmentioned benefit of the SDS will be for the first time, you'll have precise correct speed on your Aries, which without the SDS is probably just slightly off.

The Ramp down of voltage should also help with the motor, regradless of which one you have, or opt to use. Mark

Markd51 is right on. I've owned several VPI tables and not one was totally speed accurate. All running a bit fast. The SDS corrects this, isolates the table from the wall outlet and lowers the noise floor. This is why I consider the SDS the most significant first upgrade.
