Re: [Cameramakers] 120 Takeup winders wanted
Right, You can play with the shape on the end of the wire, but my solution was just a nice clean flat end, which I accomplished with an oil stone in a couple minutes. The guage and tension of the wire are other variables, as well as the pitch of the gear,but it didn't take much to get it to work. Hobby shops that deal in RC planes usually have a good selection of piano wire. If you get stuck for gears let me know, I have a surplus store that has tons of them. Good luck.

Try http://www.horology.com/hoc-susu.html for some sources of parts. I saw both LaRose and Selva there. And others I suspect both have Internet sites, but I have not checked that.

Re: [Cameramakers] 120 Takeup winders wanted
The idea with a gear is the same except for using an "unofficial ratchet". The end effect is similar except real ratchets are liable to be made from hardened steel. If your loading is light the gear should last long. Don't worry about the seemingly small sizes, especially if you can do it on a milling machine. The parts are not all that small! Even with hand work for the little ramps I expect no great trouble. Certainly the round work ought to be done in a lathe. One more thing on ratchets; they are common in clocks. I suspect can pick up the official kind from a source of repair parts. The trouble is that I have been out of this community too long. You can look for LaRose or Selva on the Internet. Selva is a German company and sells new stuff for DIY while LaRose was in the USA (East Coast, perhaps South Carolina) dealing in watch and clock parts. My last contact with them was 25 years ago.

Re: [Cameramakers] 120 Takeup winders wanted
Dwight, Theres probably a lot of ways to do it, but one that I have used before involved soldering a gear to the shaft, and having a piece of musice wire pinned down so the end of it was bearing against the side of the gear. The gear then could only be turned one way. This is hard to describe in words, if you're interested, I'll make a sketch for you.

Dwight -- It shouldn't be too difficult to find the original patent for the mechanism, which would have drawings. Marty ___ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
Re: [Cameramakers] 120 Takeup winders wanted
Several is a different story! Why not make one. A simple design I have seen depends on some bearing balls which run on little ramps. There is a drum and a disk inside it. The ramps are cut into the edge of the disk. For one direction of turning the balls roll up the ramps until they jam against the inside of the drum which is then turned. For rotation in the other direction the balls run down the ramp and bump a steep slope (vertical wall!) and so no climbing or jamming occurs. These would be quite easy to make in the quantity you want. A ratchet would be a good alternative and I believe you can buy the wheels if you do not want to bother cutting them.

Re: [Cameramakers] 120 Takeup winders wanted
I think I have such a thing from an old aerial camera. If no alternative offer appears I am willing to make a slight effort to find it for you. The trouble is that shipping from here is not cheap and any alternative nearer you is a better choice. I have seen such parts in copy machines so if you see one of those available to scrap, check its contents.

Well, I'm looking at doing several, so I might need a consistent setup. I want to make my own rollfilm backs. If I can't find another way, I might take you up on it.

Re: [Cameramakers] 120 Takeup winders wanted
Dwight, Most of the old folders have them. If you're interested I have an old one around here somewhere that would probably do the trick.

Does anyone know where I can get, or how I can make easily, the takeup winder mechanism, i.e. the knob that only turns one way? This will be for a 120 film camera. I'm still downloading that archives, after a couple of hours. Drats. Dwight ___ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
