I finally got my rim drive yesterday. I hooked it up, and tried it out. Right now, I have 2 problems:
1) Speed stability. The KAB speedstrobe shows that the table is not running smoothly. Just by visual inspection I can tell that this speed instability results from the belt on the rim drive. It does not form a perfect circle. It other words, the belt has a few "bulges" which cause the contact pressure with the platter to increase, thereby briefly speeding it up. How does one address this?
2) I cannot currently use the Periphery ring clamp because it contacts the rim drive. To accomodate the ring clamp I would need to raise the table about 1/2 inch. If you loosen the Scoutmaster feet enough to raise the table 1/2 inch, the table itself will no longer be stable, but will be "wobbly" instead. What to do?
Thanks.
