Hello everyone. I'm pretty new to clocks and within the last year or so have suddenly developed an increasing interest in them. Usually I just stick to watches to my tinkering, but it seems my tendency to not leave well enough alone has moved over into clocks. I've developed an interest in regulators and master clocks. I'd love to have a real master clock but cant afford one yet, so in the meantime I'm trying to build a regulator out of junk clock parts and scrap I have lying about. I used a junky Hermle 1161 movement. Removed all but the time side parts and installed butterworth bearings for the cable drum and pulleys(after a thorough cleaning of course) and swapped two of the wheels to make it 60bpm from 66bpm. It runs ok with my crappy pendulum and probably 4lbs weight. My current area of concern is that it lacks a maintaining power mechanism. Perhaps I should have used a kieninger movement? Most of the movements I use are from the 70s and 80s. Did any of the makers then use power reserves in their movements? I apologize for the case and other parts. I don't know what I'm doing and have very few tools.
