Broken Minute Hand - Help !


Michael20

Recommended Posts

Hello all, my latest project is a Uhrenfabrik Villingen Maurer Pfaff & Maier clock (pics attached) the face is marked DRP No 94099 which I think is a German patent number issued in 1897.

I have the clock running and striking perfectly, but this morning disaster struck whilst setting the time - the minute hand snapped. I suspect this is due to a previous repair having failed as I can see what looks like a small brass tab on the reverse (see pics)

I have tried soldering the 2 pieces back together but this obviously isn't going to be strong enough. Any suggestions about the correct way to effect a lasting repair would be greatly appreciated.

I would clean it up. Cut a little slot where it goes into the piece that has the square and solder a small brass plate to to hold the two parts together. Yes you are right it is a German Strike and it has inside count wheel strike, should be 8 day duration. People break hand off because they move the hand by the tips or ends always move from the center.

    • Hairdryers works surprisingly well. They blow hot air which is perfect for driving.
    • Interesting pictures on the timing machine? The problem with timing machine diagnostics is it's missing information a lot of times? Like for instance all the questions that were asked up above would be helpful for us to understand what's going on. Then the classic question I like to ask is what is the prior history of the watch? Was it serviced before you is a brand-new movement and then there's probably a dozen other questions but we just need more information timing machine looks good in one and bad and the other and that's not enough to understand the problem other than it's definitely looking bad oh and when you have what's called the snow globe effect the numbers are worthless also they mean nothing. Oh I did think of a question when it's doing that how long does it do it and if you change the position of the microphone like I assume this is dial down changing to another position does anything change at all?
    • Hi, Does anyone have a recommendation for a drying plate after rinsing parts in an ultrasonic ? I don't have a proper cleaning machine with dry cycle unfortunately. Thanks, Steve.
    • How suddenly does it encounter this problem (every 2 minutes? hour? 2 days?)? Do I understand right that it was doing this, and then you serviced it, and the issue remained unchanged?   How did you clean the movement? Did the gear train run freely with the escapement out, with just a couple of clicks of wind, prior to oiling? Did you service the barrel? If so, did you use proper braking grease on the barrel wall? (Kluber P125 or similar) What lubricants did you use, and how were they applied? Did you oil the pallet fork pivots? They should be unoiled, and spotless (the jewels too of course, and should be manually additionally cleaned in the hole with pegwood). Are the balance jewels properly oiled? Is the hairspring true and centered? Is it demagnetized? Any chance of some clear close up photos of the movement, in particular of the balance and hairspring?
    • I remember purchasing an assortment of blued steel wire once and I had to wonder if maybe it was actually died blue as opposed to actually blued steel and I'm sure it was from India even though is a long time ago. My favorite examples of things like this I was at a lecture were somebody made a cutter of fly cutter for cutting clock gears and skipped one of the steps for hardening. Normally when you harden something it should be very very hard before you draw the tempera you normally take a file to verify that it is actually hard that step was skipped. Off he went to cut his wheel and is cutter actually folded over on itself because I think it might've been stainless steel. Or somebody else was in someone else's shop needed some flat steel ran down to the miscellaneous scrap found a piece of I think it was packing steel but it was blue in color. In other words the steel tape they put around big packages like pallets and things and whatever it was it totally sucked for the part he was making as usual typically finding out way too late in the process say yes it really works better if you know exactly what you're dealing with even if it did come in a package with says blued steel. Just because it's blue doesn't actually mean well much of anything to be honest.
