Hey guys,

I notice in further examination, that the left side feeler roller is slight raised along with flange. Also looking at it straight on, the gap between roller at the rest of the camera is uneven. Can someone check their camera really quick and feel if that flange is running straight across evenly (the bottom one)? standing by.

Feeler roller = take-up roller?

Rollei 3.5f. my bad.. it's the single roller just below film opening. Not the feeler. the flange just on the other side has a very slight ridge on the corner where silver guide bar on the left meet. does that make sence? standing by. There is a screw just below roller in the center of roller. Not sure if that is an adjustment screw or not. I'm not touch anything. until I know more.

If you are talking about the roller just below the film gate then yes that screw loosens and you can completely take the roller out.. very simple thing to do. You won't hurt anything by loosing that screw and straightening the roller. The roller above the film gate at the take up is actually identical and interchangeable with the roller below the film gate. Because the FX has black rollers I took the top one out of mine and changed it with the chrome bottom roller in the F so now both cameras have a black roller on the bottom which reduces the roller reflection you sometimes get.

Yes that screw in the middle holds that roller in place just loosen it a bit and straighten the roller. It really is simply that one screw and the roller assembly has a slot. If you loosen that center screw you can lift that roller right out of the camera.

What about that flange on other side of the roller? It mirrors the same un-eveness.

It looks like flange is connected to very end of roller on left side. So it will move at the same time.

Ok I just did it to refresh my memory. You can just unscrew that screw in the middle, it has no other function but to hold the roller. Be careful it is small and you might drop it on the floor.
Then the roller with the film mask and all pulls out.. very simple. Just put it in straight and put the screw back in and tighten it.

Probably none. The film travels along the film rail and is held in place by the pressure plate. Exact straightness of that roller is probably not important... long as it is sort of close.

I've had a couple of Yashica-Mats with canted rollers. The symptom was the film frame being slightly rotated from parallel in relation to the edge of the film. So each frame was rotated maybe 1-2 degrees. The frames all aligned vertically and stayed on the film. Just each individual frame had this slight rotation.

Maybe how if you have a roller track like in a warehouse, a box can roll at a skew but still roll straight??

That's the only effect I've seen.
