Repairing missing Bay III mount on Tele-Rolleiflex

[Dan Daniel]

I recently bought a Tele-Rolleiflex. It was missing the Bay III mount on the taking lens. I thought it would be pretty easy to move a mount from ap arts camera, but it didn't turn out that simple. Still, it did work, it holds filters well, and it holds a lens hood and lens cap-

Thanks for posting, on mine the Bay III mount is crooked but all the parts are present, this will help me to put it back where it belongs!

Seems people had a habit of dropping these front-heavy cameras on the lens hood, no other way I can explain cameras with missing or crooked Bay III mounts...

Nice work, Dan! That lathe is paying for itself already. 😉

Johan, I think you are on to something about the heavy lens breaking off the bayonet mount on these cameras. I've dealt with dozens of Rolleis with bayonets and this is the first time I've seen it.

The Bay III piece has a flat at the point where it meets the viewing lens bayonet. And the spring system on a Tele-Rolleiflex is still a mystery to me. There were holes in the top of the taking lens shroud that matched the solid pins. But nothing for the spring-loaded pins. Not much room for any active mechanism in that space best as I could tell, and I decided to do a pressure operation rather than springs.

Yeah, Brett, the lathe is a kick. Like a Rolleiflex, a 50 plus year old machine still has some guts left. I assume this is some ddisplacment disorder on my part since I am nowhere near as smooth and accurate as these things. Seems the creakier I get, the better my tools get!
