Hi,can anyone tell me why the camera is firing at all speeds but when you set to t/b the shutter arming lever is stuck.it won't arm. Is there a spring separate from the other settings that's came loose?also do you really need these bulb settings do many people use them |

Some vintage shutters use the B and T function without arming. Just set on B or T and press the button/lever with NO arming.
Could you give us the name of the shutter ?
Many vintage cameras were produced in a period when film sensivity was really low. So long times and B or T were then used much more then nowadays with or high ISO films.
Most of the time people nowadays only use them in very low light situations (e.g. night scenes). |

Guess your camera is then a Prominent 6x9 or Bessa I.
The shutter needs service.
The mirror i don't know as i have no experience with either camera.
Maybe only problem is that mirror (when used in camera) fell off and needs to be re-glued into position. |

Actually yes, my hobby is camera repair so i use these functions all the time when collimating lenses. Last time i used B for taking photos was 25 years ago when photographing a fireworks display. |

Have you ever made spacers for a 116 roll camera to take 120 roll |

On the mirror you can make a new one but its a bit challenging.
Mirrors in cameras are what are called first surface mirrors. Basically most mirrors I.E. the ones in your car or bathroom have the silver of the mirror sandwiched between the glass and some backing paint. A first surface mirror has the silver on the top and then the glass under it. This is done to prevent distortion of your image as the light passes through the glass, instead it just hits the silver and goes right to the ground glass.
Now there are a few places online that make true first surface glass and plastic mirrors. But I, being a broke collage student, found another way.
Jo Ann sells this plastic mirror sheet, (http://www.joann.com/darice-6-x9-plastic-mirror/xprd77619/) its real thin so you can make it the same thickness as the mirror that's in the camera. (The thickness of the mirror is also important, try to get it as close as possible.)
Then what I did is just cut out my mirror and then dunked it in a cup of Simple Green, an outdoor cleaner, for about 10 min. (in hindsight you could do this just as well with water) Then I pulled it out and scraped away the paper backing with my fingernail. Then I used a paintbrush with a bit of turpentine on it and as gently as possible removed the adhesive that was holding the paper on.
Try not to touch the silver surface with your finger its a very thin layer of silver and will come off at the slightest touch. Mine came out with a lot of little scratches from the paint brush bristles but once the mirror was in the camera you couldn't tell. And if you mess it up the first time you got the rest of that $4 sheet to make a few more.
Of course if your mirror is a "normal" thickness (unlike the one in my Voiglander Brilliant) you can just take any old glass mirror that you've cut to the right shape and soak it in some acetone to remove the paint backing, and use it. There are also ways to chemically re-silver a mirror I've seen kits that cost around $50 that you can do on your own at home. Also most any collage chemistry department has the necessary chemicals to do re-silvering. (http://www.youtube.com/watch?v=hUX_cpFWNso) Assuming you can talk them into letting you use them. |
