Nils,
Saw your post recommending the CI wheel with Soldner foot control. I
have two CI wheels. I bought the new one because I loved the old model,
but actually prefer the old design. New ones have the delayed response
to the pedal. Why do you use the soldner control? Will it work on the
old model too? I have the old high duty wheel with flat black table
which is so much easier to clean up than the new molded version. Just
scrape the old one off wet or dry. It also takes up less room in the
studio. The new one involves scraping, sponging and trying to get clay
out from under and from around the CI logo. I'm thinking of pouring
epoxy or something up to the top of the lip to flush it out making clean
up easier. I'd love to fix up my old model, and I think the new foot
control might be the problem. I've had the motor looked at, and it's
been pronounced "ok". Wheel bogs down under pressure. I guess it
could be bearings, but they're not roaring, and CI thinks it's the foot
control. I hate to put that computerized "improvement" on my old
faithful. How does the Soldner control work? Why do you recommend it
over the Creative industries foot pedal? Thanks in advance, Sam

Sam, I agree with you about the molded surface on the CI wheel and I
wonder if it could be sanded down with a disk sander. Your idea of
pouring on a coat of resin would probably work too. The Soldner
footcontrol is very smooth operating, holds the speed and extremely
durable. It works differently from most other controls because the pedal
operates a variac which controls the AC (voltage) directly before the
current is changed to DC. Brent, Pacifica, CI and others use an
assortment of SCR's (silicon controlled rectifiers) in the footcontrol
changing AC to DC at the 115V level, then with a potentiometer adjusting
voltage to the DC motor for speed control. In Soldner's variac control
the AC is adjusted directly then rectified for speed control. The
difference is: no hum, very sensitive speed control and longer life in
the rectifier circuit.
Hope this helps, Nils
