Hi All,
I have a Fed Micron 2 that used to work until yesterday that stupid me had decided to blow some silicon lubricant oil against the shutter blades.
I did this from the side of the film chamber, and now it clicks, but the blades stay close. Is there a way to fix this? Have I blow away something that moves the blades, or are they simply stuck? |

G'day Nikos,
Well, what has done the damage is simply that oil you have squirted into the shutter. The blades are supposed to be dry. Any oil at all on the blades sticks the finely polished blades together just like glue.
You will need to clean all the oil out now. You might have some success swabbing the blades repeatedly with cotton buds (Q-tips) soaked in a suitable solvent. Naptha, the fuel used for cigarette lighters is commonly used for this purpose.Regards, Chris |

I will go out to find some Naptha and clean the mess. Should I let any drops of it on the blades, or I should only use the cotton buds to clean them up?
Thank you very much Chris. |

G'day Nikos,
Don't drip the naptha onto the blades, just wet the cotton buds and use them to swab the blades. Hopefully the cotton buds will absorb the oil and leave the blades clean and oil-free.
Once the shutter does finally work again, repeat the treatment to remove any remaining oil.
Regards, Chris |

Hi Chris,
I have tried, but without any luck. I had set the shutter to B and pushed the blades open with a small flat screwdriver, and I could see them sticking unable to close back. After trying a bit more with Naptha, if I open the blades with the screwdriver now they seem to fall back easier. But they cannot open yet. It seems that I had the an overspray of oil all over it.
Will keep on trying though. I might get to removing most of it.
Many thanks,
Nikos. |

Hi, Nikos, if you slip with that "small flat screwdriver" your current problem will perhaps turn out to be the minor one of the two you are facing then, as a scratched lens or blade surface is something heavier than sticky blades.
Put that silicon oil as far from any camera old or new as you can, maybe it is useful in the garage or helps you to repair the lawn mower.
Never repeat NEVER use it in, on or even just near photo equipment. It "travels", so after a while it will creep over the whole gadget if you spray it on one edge. Removing that smear is a pain-in-the-ass experience.
Use a wooden toothpick to fiddle with the blades and try to develop a little more perserverance. Cleaning oily blades has to be repeated seveal times, cleaning them from what you sprayed on them can mean several times by ten! |

Stupid me! Still, after hours of cleaning, no luck. Now I will have to buy another one! |

The shutter can still be fixed by cleaning, but I'm afraid it will require disassembly. Unfortunately I do not have notes to help with the Micron, though maybe someone else here has experience with it. |

I have tried disassembling things from the front of the lens downwards, but I had come to a solid metal block that cannot be removed. I have searched for guides on the Micron, but have found nothing so far. |

AFAIK (from fading memory, there is no Micron 2 in my possession right now) it is very similar to the Konica 35, but that Soviet remake clone camera has a more complicated light-meter which you better do not touch. Cleaning the blades from one side only is perhaps not enough, if you go in from the front readjustment of the front lens group is another time consuming procedure. Also if the blades are still wet they won't move as they are supposed to.
In the past I owned two of those cameras, and both were fine picture takers, so keep on trying.
The last time I laid my hands on one is ages ago, but apart from the meter it is a rather close copy of the Konica 35. See this source for details http://endoscopy.jp/moto/camera/camera_repair/c35/index.htm
In that same source there are some other useful articles exposing the internals. |

Indeed pretty much alike my Mikron! I have managed to open it, clean the blades and put everything back (which has been a lot harder).
Now everything, but its dead meter, are working perfectly!
The only thing that remains is find some glue to put the leatherette back on it.
Million thank you for your invaluable link! |
