I have a Nikon F upon which I wish to carry out major surgery for a project that I have in mind. It works fine but when I remove the mirror box the shutter will not fire. I have the service manual but cannot figure out which bits connect together (as in 'the knee bone connects to the thigh bone etc.') What I want to do is to remove all the unnecessary parts leaving just the body with working shutter. Does anyone have the time to help me? |

I will try to post a better response later, though my digital macro capabilities are very canty.
I have a gutted F here. There is one lever that, if moved, allows the shutter to fire with the mirror box off.
If you look at the camera, facing the front, you will see a little crank near to the right hand side of the opening where the mirror box was, near one of the curtain rolls. It has a pin sticking up. If you push that crank back, the shutter will fire.
With the base plate cover off, you'll see that this crank actuates a pair of crescent-shaped levers, at the end of which is a pawl which engages the main shutter roller.
I think you could just remove the lever that has the pawl on it, or you could add a washer or something to one of the pivots, so that when it's screwed down, it jams the linkage into position (that would insure that no parts are removed and lost if you have future plans for the camera).
My cursory investigation suggests that those parts are about all you'd want to remove from the basic body, since all the rest of the mirror and viewfinder related stuff comes off with the mirror box.
I'll try to take a photo later, and show which parts I'm talking about. |

OK, let's see if these pictures work:
One shows the lever, one the pawl that the lever ultimately releases.  |

Bingo!I had tried pressing that lever but had not tried pressing the shutter release button at the same time. Thank you very much for your quick response. Now I can move ahead with the rest of the project. |
