[Dan Tull]

You got it.-  Point loading.
Tapered point riding on a ball bearing.
The larger structures need bearings.

> I just fixed a large wind sculpture for a client here in town. Not
especially well constructed. The fellow who made it tried to solder sheet
copper "vanes" to a stainless steel round stock shafts. Not too durable of
solder joints. Aside from that I became intrigued by the whole idea of wind
sculptures. I know some time back there was a thread on weathervanes and how
to make the "bearing" so they spin freely.

> Anyone have any hot tips on designs that would allow a fairly heavy wind
sculpture to spin freely? I have some ideas on how to adapt a typical
weathervane system, but with a sculpture of any vertical height I am
concerned about maintaining axial position as well as point loading for free
spinning.
