    Default Richter Patent Tuners

    I came across a couple examples on ebay, and since (I think) they haven't been discussed here since 2007 (LINK), I thought I'd start a thread.

    My question: Does anyone have an instrument using these unique 'brake cam' tuners in playing condition, and regular use? It's kind of a brilliant idea - except for the expense, intricacy, and the fact that I imagine slacking the strings to bring them 'up' to pitch (and indeed all aspects of real-world tuning) would be nightmarishly difficult. Other than that...

    Hi BradKlien. My name is Mike and I'm the proud owner of the Richter tuners shown in the left 2 photos I purchased on Ebay and came from Poland. First time I've seen this type of tuner. I too would love to see see them in action on a working mandolin. Unfortunately these were attached only to the neck part of a mandolin.

    Hey Mike. I'm surprised no one stepped forward with real life experience with these lovely oddities. But someday, I'm sure...

    Im curious about the string path after it leaves the capstan on the front
    it goes around the roller?

    is it a 1:1 gear friction tuner . with a little Rube Goldberg touch?

    I imagine that the string goes around the 1:1 post, then around the cam, so that the tension on the string applies a 'brake' preventing the tuner from moving.

    FWIW, Friction tuners, on a short scale steel string is a real PITA to get on Pitch.

    I suppose it needs all the help it can get ..

    So , Put Nylon strings in their place .. the elasticity makes it a bit easier ..

    Looks like a "pocket" mandolin. German made?

    Very cool! More photos would be nice. I have one of these that someone gave to me, which I am cleaning up. (I won't say how long this project has lasted so far. ) So far I've just been cleaning the tuners up. It has had a hard life and I'm not sure I'm up to any real restoration work. I'll see if I can get some pix posted.
