Dear Phil,
You suggest employing ball bearings<< intend to make some versions =
of...Timkin and heavy 'Ball' Bearings and standard Alemite =
'Zerk'fittings.>>
One of the thing which has perturbed me about potter's wheels is the =
style and quality of bearing incorporated into the design. Since I came =
to Oz I have used Venco Wheels. The first I bought needed a new bearing =
sleeve after twenty years of wear.
But when I constructed my own treadly wheel, to my own design some =
thirty years ago I wanted to have good bearings which would take a good =
mass of clay and stand up to the pounding. So I used a set of Thrust =
Bearings which, as I recall, had tapered rollers, not balls, under the =
wheel head. The lower bearing ran in an oil bath. Ran smooth as silk =
with a fifty pound rim flywheel.
I recall seeing pictures of a wheel which used an auto rear axle and =
wheel. The wheel was loaded with Water.
Best regards,
Ivor Lewis. Redhill, South Australia

Hello.
When I built my Treadle wheel, I used automotive tie rod end bearings for
the treadle mechanism. They are smooth, strong, and not too expensive.
