. I still have one, which is slightly used, so I decided to replicate it in my favorite material.... you know 
. Of course, some brass elements should be used as well, that is manly to prevent INOX seizing (very bad thing I must add). Some parts of the original polar-mount, I change already, such as declination adjustment, elevation bolt setup, connection to vertical 76mm pipe. So, my pilot version is more or less ready. In addition to CM antennas, the polar-mount will be capable to hold Cahors 1.2m antenna. BTW, if somebody has great ideas to be incorporated in the build of the polar-mount, I am open to listen.
Azimuth fine adjustment, like some CM Rx/Tx dishes have, would solve the biggest problem (IMO) of the original polar mount. How easy it would be to implement, I don't know. These days I just rotate the pole rather than trying to turn the mount on the top of it. With the original design the mount inevitably turns when tightening the 3 bolts, your design looks like it may already improve this?
TBH, I do not see an easy way how to do that. Maybe you have some ideas (pictures)?
Like on this mount from your sat playground thread:
Aw, I see.... I will find this mount somewhere and look closely to its construct.
Bearings are similar to that CM polar-mount has. Bronze body with INOX insert. Perhaps a drop of oil can be added to make movement smooth. I was also thinking about teflon, will probably try it as well.
I made one out of teflon. Firstly, there is no play between the ring and the bolt. And secondly, the mount moves very smoothly, I think. But I do not know how it will behave over time. Only tests can testify the concept.
Some time ago, I got my hands on 10 CM polar-mounts for a reasonable price. Some of them were presented to friends of mine, some were sold and shipped to members of this forum as well. But, no original CM polar-mounts are available
