    herschede tube sizes

    Anybody have the lengths of the set of Herschede 9 tube for the 1 3/8 diameter tubes? Randy used to sell these tubes and had them listed in his catalog but since he stopped dealing I have misplaced my copy. I am sure there are more than one set of measurements, if you have a reference to a set...

    American question about Waltham tube clock dials

    I have four Waltham tube clocks and I notice the fretwork and center of those fancy dials are different. Two if them are hand cut similar to Herschede or Elliot but two of them are cast or poured soft metal with a brass or gold plating. From a few feet distance they all appear to be made the...

    IBM DIAL COLOR

    At quick glance the round dial of an IBM master clock would be called black numerals on a white background but on closer inspection the white starts to have a little brownish [?] in it or maybe some grey or maybe oyster. I am curious as to what other people see when they look at it, is it white...

    IBM curious questions about IBM master

    Two curious things I noticed about the IBM works: firstly at each arbor on the plate where the arbor goes into the plate there are some cups which look like oil sinks but are not shaped properly and are usually facing in. My suspicion is that they are punched at each location during manufacture...

    one minute impulse device

    I rigged up a device which moves the winding ratchet one tooth a minute. I replaced the original 59 tooth wheel with a 60 tooth wheel to avoid over winding. I ran it a few days and its working fine but I am afraid to just let it go so I stopped it. I cant tell from looking at the spring if it is...

    invar / carbon pendulum rods opinion

    I am making a few pendulum rods out of carbon fiber 1/4 in shaft for seconds beat time only clocks. The bob is a cylinder 2 in. dia. 10 inches long, similar to that of IBM master clocks. All the information I can look up tells me that carbon fiber has a coefficient of thermal expansion smaller...

    Timing marks on vienna reg strike train

    three contacting gears on the strike side have small circular dots on one of the arms of the gear. To me it seems obvious that they have to align somehow. I can see a few different ways they could line up. I don't know the designation of each gear but they are the one with the pins that lift the...

    Question on International mercury pendulum.

    According to all I have read the International 60 beat master clock has one of three different pendulums. The one with the double steel tubes is supposed to be a mercury pendulum however I have, over time, had three different people tell me that in spite of a very similar appearance not all the...

    Anybody know what this is?

    If I can figure out how to post a picture. Has anybody seen this model before. It looks like a Seth Thomas case but is obviously International. The screws holding the dial on suggest its not the standard International movement nor is it the weighted wind system. I dont have this clock but...

    international escape wheel size

    I am going to make some escape wheels for the international 60 beat master clocks. I have several and have measured the thickness and diameter of those that I have. Due to having been used over the years and who knows what other factors I end up with about 0.010 discrepancy across dozens of...

    international weight driven weights

    A quick question for anyone who knows. I believe I read somewhere that the driving weights for an invar pendulum and a mercury pendulum is different than the weights for a wood stick pendulum. If anyone knows the difference it would be great if you could pass on the info. I think I remember...

    gear sizes of ITR IBM models

    I recently got several IBM master clock works all of seconds beat. In measuring the diameter of each gear of each model I noticed a variation of 30 or up to 60K difference yet what installed they all seemed to be interchangeable. I know clock gears do allow some slack which frequently saves me...
