I know that some wheels of the past (and maybe present for all I know)
used a cone arrangement to vary the speed of the wheel. Just wondered if
anyone knows about those wheels, or where the cones can be acquired. Or
for that matter where any cones of any kind can be acquired.
Thanks,

John -
The Shimpo RK-1 uses a cone-drive. The cone is mounted on the motor output
shaft. About twenty years ago I bought the cone and the rubber friction
ring from Shimpo, and then built the rest myself. My primary incentives for
doing so, rather than just buying a Shimpo, were that I like to design and
build machines, and that I wanted an over-sized Shimpo. Mine is about
half-again taller than a Shimpo RK-1, and is very comfortable to use.
Just contact any Shimpo supplier and tell them you want to buy the drive
cone for a Shimpo RK-1. If you are building a wheel, you should buy the
rubber friction ring as well. It is very hard rubber, and it would be hard
to improvise something that works as well. The inside bore of the cone will
be metric. You can either buy a motor with the appropriate metric shaft
size, or else have a machines bore out the cone to a standard American size.
I think I had mine bored out to 5/8".

I have an Amaco wheel made by the Robert Brent company. (Brent is a part of Amaco).
I don't know how old it is. I think it is at least 20 years old. It has a steel
cone sticking out of the motor that turns the wheel when it is pushed against a
rubber wheel. I saw parts, including cones, in a catalogue from the A.R.T. Studio
Clay Company. Their number is 877-ART-CLAY (I hate having to figure out the
numbers). The order number is 800-323-0212. I hope this helps.
