Hi there,

Hm, interesting, I was preceisely considering some thing of the kind:

 it is a large ball-bearing-based ring that a local company can supply in
sizes up to
a bit more than one meter. The normal ;-) use if those seem to be for 2
axes trailers,
where one axes can be rotated around a vertical axis. They are dimensioned
to
support several hundreds/thousands of Kg/lb (anyway, overdimensioned, that
is).

Do you think it would have the same defaults as the mentioned lazy susan?

TIA, and have a good week-end!
