    How to replace pinion, which punch?

    I have a common 16s Elgin (model 291, 7j). The 4th wheel has a broken pinion. I have a spare pinion. I removed the broken pinion and was ready to stake the new one on to the wheel. I stopped. I have never done this. Am I using the right punch, I asked myself. I was about to use a flat hole punch...

    Thanks, D.th.munroe. I have not been on in awhile, so just catching up now.

    Recommendations for a timing machine?

    Thanks everyone. I found Clock Tuner. Is this a free app? Looks like I would need to buy a microphone for a pick-up, correct? I see the Timegrapher 1000 on line for about $150. Rather old school compared to an app. That appeals to me. I will check clock master next. John

    Recommendations for a timing machine?

    If anyone a recommendation for an inexpensive timing machine, I'd like to know. I've done a google search. They seem to come in around $150 to $250. Anything that just gives the beat? Don't need a print out. Thanks. John

    Elgin 12s: location of guard pin--where?

    I meant roller jewel. I was occupied with the guard pin for awhile and forgot I meant roller jewel. Thanks for catching that. OK, you have answered my question. I've been rotating the hairspring but not sure I have it in the optimal position. Fully assembled, it's hard to see the position of the...

    Elgin 12s: location of guard pin--where?

    I've been futzing with a common movement, an Elgin 12s. When the movement is completely run down, i.e. no power being transmitted through the train and the balance is in the equilibrium position, where should the guard pin line up with respect to (1) the banking pins and (2) the lever? Should...

    16s 7j Elgin with double roller

    Seems odd to me that a rather lower grade watch as this 7j Elgin IS/N 1998664) should have a double roller. This one has damaskeened nickel plates. I have the same movement in brass; single roller. i looked the serial number up in two databases. The descriptions are spot on, just no mention of...

    Winding arbor bushing--how much bigger?

    So what I should do is make the bushing a bit longer than the width of the plate, then use a rounded stake to flare out the bushing, followed by a flat stake to make the rivet. Am I on the right page? Sounds like this could be done on both sides of the plate..

    Winding arbor bushing--how much bigger?

    First, thanks to both of you. I looked at the functions in the spreadsheet and realized that the spreadsheet is used to calculate the inner diameter of the bushing in order to derive a certain tilt angle. I'm afraid my original question was unclear--sorry about that. My question was meant to be...

    Winding arbor bushing--how much bigger?

    I have a job in mind but may be awhile before I get to it. The winding arbor needs to be bushed. If I turn a bushing to the proper size, how much bigger than the hole should it be to get a proper fit?

    Loose canon pinion--how to fix?

    Here you go. After I got the clock, i discovered it did not run. This was due to the pendulum rod rubbing against the weight. If I pushed the weight away from the rod, the clock ran well. I thought the weight was put in backwards, and so I switched it around. The rod seemed to be free and the...

    Loose canon pinion--how to fix?

    Bruce: I finished putting the clock back together today. Once I pinned the hands back on, the hands moved properly. It's ticking away now and keeping time. Thanks for your insight. John

    Loose canon pinion--how to fix?

    Bruce: You have very accurately described the situation. I just got the clock. I took the movement apart and cleaned it. But I never fully reassembled the clock, that is, I did not repin the minute hand on. The hour hand is a friction fit. I placed that on yesterday and set the pendulum in...
