Hi all,

Re: Favorite 1961 Fed-2c

The frame counter in the large "mushroom shaped" winding knob, is stiff when attempting to Reset on frame # 0 with a new roll.

How can I release tension on it; there is no central top screw?
Thanks, Mike
 
The knob is locked onto the shaft with a screw in the side of the knob, loosen this and the knob can be unscrewed whilst the fork (which engages in the cassette) underneath is locked with a screwdriver or such. The disc with frame numbers is sandwiched under this knob, you should find a spring washer on one side of the disc. Maybe a clean up and light lube would help.

Before you attempt to disassemble anything, try a non-invasive procedure first :).

First, the counter isn't tensioned. It's just friction-driven. When the counter gets sticky or hard to turn, chances are it's just dirty.

Inject some lighter fluid under the counter dial. Use a syringe for this purpose.
And when injecting, make sure that the camera is flat on its back, so that effluents drain downwards and not into the camera's other parts. Lay it on an old newspaper to catch whatever flows down.

The counter, if it has indeed a problem caused by fossilised lube, should free up and become easy to turn. But that's not the end of the procedure yet. Get some fine oil, such as sewing machine oil, put this in a syringe and inject in very small amounts under the disc too. Probe for the main shaft and apply the oil there. Try to inject from different points.

This method works 99% of the time freeing up stuck counters.

If this doesn't make the counter disc movement easier, then disassembly is the next step. It may be that the wire spring bearing on the counter is displaced or even missing.

BTW, when setting the counter, it would do the winding mechanism good if the counter disc is turned clockwise.

Thanks guys; the non-invasive method worked OK. I'm leaving well enough alone, even if the frame counter is still a bit stiff. And yes, logic said to move it in a CW direction.

Jay, I see you're a cat fancier. I'm caring for 2 kittens in the garden.
Cheers, Mike

Mike, why not try out that I61 l/d, on those kittens!!? :)

Sure Dave...
Forgot to mention; when I move the frame counter [now moves easier],
I'm grasping the advance knob with my left thumb and forefinger, to provide "contra." All is well; only have to deal with the slightly stiff frame counter once per roll.
