The Yashicamat that I was asking about the crank problem on, has a shutter cocking problem, that I was trying to get into the camera to fix when I discovered I could not get the crank off.
What is happening is that when you wind the film, and crank back to cock the shutter, the shutter does not cock. That seems like a shutter problem at first, BUT!
If the lenses are racked out to focus closer than about 10 feet, the shutter does cock. That makes me think it is a linkage problem, but I am not sure about that. It has been decades since I last worked on a TLR, and I was not an expert back then.
So while I am waiting on a replacement crank and a recover kit (this one has the Vulcanite covering, so for sure has to be replaced, I like this camera a lot, so it is worthwhile fully restoring it to me), I thought I would see if anyone can point me in the right direction towards fixing this problem. |

Hmm I've got a Rolleflex T with a similar problem, except that it only cocks when the focus is between 6 feet and infinity. I guess the linkage from the film winding system in the body, to the shutter cocking system in the lens board, is somehow bent or worn, so it only works with the lenses in a certain position. I have used the camera in this condition but its easy to forget to rack it in (or out) and I missed some frames as a result |

It's linkage issue and quite likely you will be able to fix it without removing side panels. Remove the lens board and look for the fork cocking the shutter. You should be able to adjust the lever on the shutter side to mate with (possibly worn) fork better.
