Cirkut 10 in SF Bay Area?

["Timothy A.Weiant" <weiant@xxxxxxxxxxxxx>]

Hello again!  I'm the guy with the Cirkut 10 and no ring gear, turntable,
or tripod.  Have found a couple willing machinists, but really need to
see and measure a Cirkut 10 ring gear and tripod.  I know that the design
changed over the years, and in all the photos I've seen it looks like the
camera attaches to a turntable atop the ring gear.  The turntable and
camera turn as one, with the turntable having little wheels which roll
along the top surface of the gear. My camera has three wheels on the
bottom of the camera itself, and by measuring, I can see that the camera
itself rolls along the ring gear.

Here's the hitch:  I can't spec the inside dimensions for the machinist
without seeing and sorting out the variations on the design.  I'd like to
make a stack of gears to reduce costs, but don't want to ruin perfect
gears with a botched middle.  Does anyone know of a Cirkut 10 ring gear in
the San Francisco Bay Area? 

Ron:  In an earlier post you talked about cutting the gear teeth, then
mounting the gear to the tripod casting, and then turning the inside
dimension. 

Sorry about the multiple queries on this topic, but being a visual thinker
and not being able to see what I'm trying to reconstruct is making me a
bit nuts....

Thanks to all, Tim Weiant
