Retina iiic Shutter Diagnosis?

[grif]

Is there any way to manually cycle the shutter without the film advance lever on a iiic? Not sure if the stuck shutter is a shutter problem, or if I need to disassemble the top plate and look at the cocking rack assy.

I would really rather not tear into anything extra I don't need to.

No.
The shutter is cocked by the cogwheel inside the round thingy at 11 a clock on top of the shutter.

If the shutter doesn't cock it probably is the cocking rack that needs to be replaced. I don't know where you live, but there's a guy in Germany that use to sell them on e*bay. His username is mucmue64.

Right,,, I'm just still not sure if the shutter is jammed, or not being cocked. I guess the next thing is to pop the top and take a look at the rack.

Here's how to do it: http://homepages.ihug.co.nz/~Srawhiti/retinarack.html

You've probably seen it before, but just in case you haven't.

Found the site, I guess the visegrips and hammer come out this weekend ;-)

Not sure if I hope it's just the rack, or a totally gummed up shutter.

(I'm an old hardware and electronics tech from the computer generated and analog microfilm days, I still have really small hammers ;-) )

Well,,, got it diagnosed over the weekend. Bad rack, and what feels like a really gummy shutter. Really can't cock it by hand without forcing. It's not over yet, but the trip to see the Wizzard is on hold for a bit. I'm good enought to do the rack replacement and timing using the notes on the Chris Sherlock page. So, it's looking like one of my many month projects. I may send the lens and shutter off by itself in the next couple of months if I can find a good rack.

Good idea. Remember mucmue64 on eBay. He didn't sell all the cocking racks he had the last time he had them out on "Buy it now". I bought two from him for future projects.

Ok,,, I'll keep an eye out for him. Seems like there was one other rack for sale last week as well.

mucmue64 has the cocking racks on eBay again.
