I have a couple of 1940s Kodak 35 cameras (as well as 35RFs) that are missing some of the rollbearings and springs under the winding knobs.
These tiny cylindrical bearings and springs allow the knob/take-up spool to only turn in one direction.
Anyone know a source for these parts? I don't want to cannibalize other cameras for them. 
Kind regards,
Rick |

Managed to make some 2x2mm rollers from some wire I found in the bits box. Cut'm with a handsaw, ground'm down with a dremel and a file until they fit.
Now, to make the springs.... |

Alright managed to turn some compression springs from musical wire and hardened them.
Cut to the right length and ground down a little.
Managed to fix the roller brakes on both a Kodak 35 RF and on a PH-324. |

Impressive. I thought about turning my own coil springs for a repair last year. Nice to know it really can be done. Did you harden them while on the form?
You've prompted me to pull out the Kodak 35 and give it a look over. Surprisingly better built than I thought it would be. Mine has an issue with returning the rewind lever to "wind position". I doubt I'll tackle that for a while, too many other projects ahead of it. |

Thanks,
No, I took them off the form, which was an 0.8mm screwdriver tip. I used some excess string (high C) from my electric guitar for the springs.
Wound it around the screwdriver as evenly as I could and then cut off the excess.
This gave me enough for two springs, with some room for deformities and cutting errors
I tempered the springs by heating them over a bunsen burner until evenly red all over and then cooling in water (oil is better I'm told).
Then cut them down to the right size and carefully ground the ends a little bit so they wouldn't get caught between the roller and the sides.
Here's a shot of the PH-324 after the repair

Cleaned the shutter. Realligned the gears of the winding & tensioning mechanism. Replace a missing part of the flip-up viewfinder. And of course the bearings and spring under the winding button.
A friend is working on having some reproduction 'nomenclature' plates made up. Normally these were attached with the two rivets you see on the front of the camera.
Cheers,
Rick |

Nice looking camera. Funny how "Kodak 35" can mean different things. Here's what I thought you were talking about. Very similar, but I think this one is a tad newer.

I have an old 35 (no rangefinder)just like the one in Ricks photo and also the rangefinder model.
What really struck me with these Kodaks is the fact that the pressure plates in both my cameras are not black but shiny. Wonder how that would influence the images ? Normally one would suspect that this would cause stronger halos. |

If I recall, one of the Kodak slide films, I think Ektachrome, didn't like shiny pressure plates and that is when Kodak (and others) began to switch to the black pressure plate. |

Anything without an anti-halation layer is going to get effected (I only learned this after having shot about 10 rolls of Lucky film) ;)
Hollenbj, your 35RF appears to be a post-war one with Anastar Lens in a synchromatic shutter. I have an earlier one with anastigmat lens in a Kodamatic shutter.
Here is my war-time Kodak 35 family (without the military one in the previous photo)

And the two Signal Corps ones next to each other

Yes, the Kodak 35 RF camera in the picture has a shiny "chrome" pressure plate. Funny, I didn't even notice it. I do recall reading a recent thread about this on Classic Camera Repair. |
