Dear John,
I may have to take another photo. In my platform, the gnomon rod
extends through the base and is the pivot as well.
In principle a circular section of a cone should work. I'll also
post a schematic drawing of my platform.
best wishes,
Peter

Hi Peter,
One more image, of the pivot alone? Can't quite make it out in that
second view. The rest is quite clear.
Question: Is it still a Poncet platform if it utilizes a cylindrical
surface rather than a planar surface?
Best,
John B

Hi,
I've tried to send a couple of small jpgs of my crude Poncet
Platform, but they've been blocked by the server, too large. I may
have to try in stages.
best wishes,
Peter
