Matthew Pothier Posted March 25, 2021 Share Posted March 25, 2021 I have an Aaton LTR that is in need of repair. The "mirror shaft" is broken according to Abel cine. Was quoted to be 2000$ to fix back in 2016. Has been sitting on my shelf in my office since then. Just curious if anyone would be interested in taking this project on, would sell for cheap.

Premium Member Tyler Purcell Posted March 25, 2021 Premium Member Share Posted March 25, 2021 Does the camera run at all or does the mirror not spin at all. I wonder how you break that shaft, it's pretty darn robust. Also do you have a picture? Quote Link to comment Share on other sites More sharing options...

No idea how it broke to be honest, was quite devastating at the time since I was a young DP and had already sunk all my money into the camera. I will take some photos this evening when I get home Quote Link to comment Share on other sites More sharing options...

Just ran a test, runs super quiet and the mirror seems to rotate fine, That is about the end of my knowledge when it comes to the inner workings of the camera unfortunately. Abels exact wording was "broken mirror shaft" Quote Link to comment Share on other sites More sharing options...
Giray Izcan Posted March 25, 2021 Share Posted March 25, 2021 Wow... it sort of looks like a timing issue almost. Quote Link to comment Share on other sites More sharing options...

That was my first thought as well, But I trust Abelcine's inspection they are definitely the Aaton pros Quote Link to comment Share on other sites More sharing options...

Yea, what happens is that there is a worm gear on the end of the shaft and it can rotate on its own if something fails. So what probably happened is that the shaft where it intersects with that gear has failed somehow. I'm doubtful it's that difficult of a fix. I've remedied these issues before no problem, its just about how long will the re-timing last. Quote Link to comment Share on other sites More sharing options...

Premium Member David Sekanina Posted March 26, 2021 Premium Member Share Posted March 26, 2021 (edited) hmm. the helical gear is pinned, so unless the pin broke, i don't see how the helical gear of the mirror shaft could get out of sync Edited March 26, 2021 by David Sekanina 1 Quote Link to comment Share on other sites More sharing options...

On later caemras it is held by a screw. Only full disassembly will reveal the problem. Mirror could be unstable on other end of shaft which is more difficult to address.
