Hi, all - Well, as much as I'd like to snipe my way into another Rolleiflex Automat for our impending trip to London, prices are such right now that it just t'ain't an option. I started in to taking inventory of my current camera stock. Found my early Yashica-Mat ( non-124 ilk), and got to thinking. I got this camera a couple years ago or so. Had issues with the shutter and the advance linkage. Well, the shutter was fixed in short order, but the linkage issues have eluded me ever since. Sometimes the advance winds nicely and everything's groovy; other times, well, it just don't work. But the images I've gotten from it have been stellar, rivaling my old Automat. So, I figure it's worth the investment in effort to fix right, once and for all. Got a hold of Dean Williams, who's way more adept at this (and experienced with Yashica TLRs) than I'll ever be. He's assuring me that fixing the advance is well within my capabilities. That's all I needed to hear - I have a new (old) project! Just found all my Bay I accessories, and all the gear that came with this camera (pictures forthcoming, after I fix the bathroom faucet). I managed to accumulate a good Rollei hood, Rolleinars I and II, a yellow filter, and the Y-Mat came with a very nice matched case and metal lenscap. It's a nice rig. I'm completely stoked now. So, as usual, I'm opening this thread to chronicle my further misadventures, in case anyone's bored or, at a later date, is adventurous enough to try any of this. Wish me luck.  Scott |

Here's a before shot of the whole sh-bang:  You'll note that the front coverings are already gone. It's almost too bad - they were in beautiful shape (the rest still is), but had to come off to get to the shutter (and next, the winding train). And these coverings don't play nice - potato chip city. So, I'm thinking black Griptac as a new covering. Cart before the horse, again... :rolleyes: Scott |

That's a helluva nice outfit, Scott. Good luck with your project!

Thanks, Pete. Well, after spending not less than 30 minutes chipping away the wind-side leatherette, I got the thing opened up, and couldn't find anything obviously outta kilter. Buttoned it back up, and - voilà! - everything works. Now, I know this is a temporary hiccup in the malfunctioning, and that the problem will return. I'm still going to follow Dean's directives and snake out the problem. A good cleaning and lube, at the least, is in order. But I'm encouraged that it will eventually be completely reliable again!  |

To whit: After reassembly, the counter wouldn't reset to zero. Backed up a ways, but not far enough. Opened it up again, realigned things as they seemed they should be, and it resets correctly, sort of. Some tinkering to do there. And it seems to me that the counter shouldn't be advancing at all, anyways, without film....  |

Didja get my email with the link to the webpage, Scott?
A quick look at your picture here says the ratchet for the drive key gear is out of position.
Also I see the screw has been removed from the counter disc, so you've probably lost the tension for the spring beneath it. It wants to be preloaded enough to return the counter to zero when the back is open.

Ok, opened the side back up, again. As Dean mentioned, the ratchet on the drive gear wasn't engaged:  Washed it down a bit with some Xylene and moved it back into position:  It ratchets as it was intended to, but if it gets moved out of alignment too far, it doesn't snap back. I'm going to try and fix that - it's spring-loaded, so this shouldn't be happening. Have reinstalled the wind crank and will be loading some old (read: bad) film to see how everything is lining up. Fingers crossed. After this is lined out, I need to figure out how to load the spring on the counter. I can rotate the counter when the back's open and close the back to lock the counter in place, but when the back is opened again, the spring spins the counter back to the "unloaded" position. Not sure what to do on that one yet... |

Well, I've run a dummy roll of film through the camera a few times now. Everything's working as it should. Even the counter lines up right as I wind everything, though the "S" doesn't quite line up in the window after loading the film.
Think I'm going to load it up with some Pan-F and try it out this afternoon. Still want to lube the ratchet first, though. But everything seems to be happy. For now...

Test roll of Pan-F is drying now. Images look great - sharp, well-exposed, evenly spaced. Only issue remaining is that the first frame is right at the edge of the backing tape. Not sure if anything can be done about that. Time to order a new covering...  |

It is a little confusing with two threads on the same project / camera. Hard to follow from start to finish. Just MHO.

James -
I opened the new thread with the photos separately, as I consider the results something different from the ongoing DIY stage of things. I'll take it under advisement in the future, though.

Ok, camera's still jamming intermittently. Took the front standard cover off today, and when it jammed again, I started piddling with the release linkage:  I pushed the little bent lever thingy circled in blue to the right, which in turn slid the little tab circled in red to the right, also. Nothing noticibly changed, but after the two pieces slid back to their rest positions, I could wind the film forward again. Makes me think something's not aligned quite right, and (occassionally) restricts the travel of the pieces and parts. Ideas? Scott |

Oooh! Progress! When the shutter release is tripped just lightly enough, the shutter opens, but the linkage doesn't release, and the winding arm is locked. If/when that happens, depressing the shutter release again doesn't trip the shutter, but does release the linkage... :eek:
