    Help with a Schmeckenbecher Regula-25 clock mechanism

    First, try running the clock without the pendulum. It'll go fast, but if it goes at all your problem is thhat the pendulum rod is rubbing something. If it won't run even without the pendulum, make sure that the hands aren't hitting something and then pull out the movement and see if it runs...

    They're often mentioned in old clock advertisements, along with 'cut steel pinions.' The idea is that they're supposed to stabilize and return an extra drop of oil to supplement that which is retained between the pivot and the wall of its hole. I don't think they work. And the solid pinions...

    One of these days someone will figure out what oil sinks are actually good for. They weren't used in every clock, nor were they ever used in AC-operated electric clocks, nor in industrial timers. Nor in alarm clocks, forsooth. M Kinsler

    Parts for a cuckoo clock.

    These are all standard modern cuckoo clock parts. Try giving the entire movement including the chains a week-long soak in charcoal-lighter fluid, then remove it, let it hang to dry for a couple of days, and then hang the weights and try it. M Kinsler

    0.6 mm, 0.7mm, 0.8mm, and 0.9mm are used in the upper wheels of all three gear trains in German clocks. As for my advice about precision, I meant that you should choose a bushing that has a bit of slop in it when tried on the pivot. This isn't always so obvious, so you'll do a good deal of...

    Puller

    I don't have a photo, but given the front plate with only the T3 wheel held on by the cannon pinion, we chuck the handshaft into the drill press chuck and, having backed up the plate itself on the drill press table, operate the big feed lever on the drill press to push the handshaft out of the...

    Puller

    I've been using my little Harbor Freight bench drill press. Place the plate gear-side down so the gear extends into a short piece of 2" or so PVC pipe placed on the drill press table. Adjust the table and chuck the handshaft into the drill press chuck and tighten it with enthusiasm. Move the...

    Clock novice - first post (Regula-34)

    If you do fix the old one you' and the customer will be wise to keep it a secret, lest three dozen more crippled cuckoo clocks find their way to your doorstep. I'm not kidding: everybody on earth has a dead cuckoo clock in a shoebox in the attic. M Kinsler

    In what way do the pivots wear out? I've only seen mushroomed pivots in steel plate clocks. Provided that the pivots are reasonably well polished I don't think that the bushing alloy makes any difference. Note that brass bushings are presumably made of whatever brass alloy that the maker felt...

    If the bushing is a bit longer than the plate thickness you can place one side of the plate on a flat anvil and apply a healthy clop with Mr Hammer to the other end of the bushing, which will squash tightly against the sides of the hole, never to move again. Then you'd broach out the bushing...

    Nope. You'll be making some yourself. Clocks were wearing out long before there were store-bought bushings. I generally have to make them for winding arbors. I've generally used bronze bushings because they look kewl, but I use brass ones, too. For German chimers you'll want tiny 6mm...

    Thank you, Mr S. Bug. I'm still scared, but that helps. M Kinsler.

    I've never loved factory bushing assortments, so I use old pill containers to hold 0.6 mm to 2.0 mm (by 0.1 mm increments) KWM-type bronze bushings (Timesavers) in various lengths. Mark Kinsler

    Thanks. I edited it after I tried it out. Can you try it now?

    Conservation of antique paper

    This Smithsonian Magazine piece seemed relevant to some of the non-brass repair work we do. Note that there is a small amount of political content in the text. There is some sort of unspecified 'treatment" involved, but overall I found this fascinating...
