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. Good luck! Bob _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
