I have WWII Robot camera ( with long spring motor winding knob) without a lens. It has jammed shutter. I tried it today and it started to work at 1/500 settting, then it got jammed again in open position. It looks like it needs cleaning and lubrication. Does anybody know how to disassemble Robot II?
I have another Robot II with ordinary knob and also without lens. That one works OK, but does not have a rewind knob. Does anybody know where to get a rewinding knob (if possible) lenses?
Is a service manual available for Robot? |

Just a saftey tip:
As I understand it, the Robot has a coiled steel spring, much like on some clocks and watches.
Be careful when taking such a machine apart-- it can be dangerous. No kidding.
Guess how I gained this bit of knowledge?
If the shutter got jammed, and someone kept winding that ratcheting spring tighter and tighter, then that spring might be storing a surprising amount of potential energy. There may be two or three feet of spring steel in there waiting to jump out, and that steel can cut like a knife.
Put on some safety goggles before you take it apart.
I think the trick is to first (BEFORE dissassembly!) find a way to move the pawl off of the ratchet teeth, so that the spring tension can slowly be released. |

The shutter assembly is accessible from the rear after removing the film windowhole with quite limited disassembly of the camera. But watch out for the spring indeed - a loaded spring can cut off fingers or severe a vein! |
