Thank you for all the replies.
It is indeed the Brandon model.
It was given to my client in 2018 and it ran until a little while ago. He explained that it ran fine and kept time but suddenly developed sort of a double tick and became unreliable, sometimes running for a few days or only for a...
I don’t like magnetic screwdrivers, sometimes it’s a blessing, but most of the time, it’s a curse.
I also don’t like to bring anything magnetic near a clock. It may or may not matter, but I don’t like it, and I don’t do it. I use this instead.
long tweezers I bought from a medical supply place...
I just grind the blades of my standard screwdrivers to fit.
I use a small grinding stone in my Dremel and hollow grind the blade as per the picture. That way, the screwdriver applies pressure at the root of the screw slot preventing the head from being chewed up.
Exaggerated for clarity.
Totally agree. I’ve experienced the benefits myself. sometimes I feel like I should make it a standard operating procedure, like pivot polishing and pegging, especially on Urgos 32xxx series. I haven’t yet, but I think I might, whether it seems to need it or not.
I know someone who always...
I think that the hammer is already lifted and just about to drop at warning. The train may have difficulty starting if it’s preloaded by the hammer, it normally needs a bit of ramp up time before it starts to lift the hammer.
Can you change the wheels timing to allow such ramp up?
The best way, to be absolutely sure, is to measure the distance between the bottom of the can to the lid when closed. It’s not easy to accurately measure but here’s a method.
use a bolt, rod, nail or whatever else you find that will fit in the arbour hole. A close fit is preferable for best...
Well, one side of the bushing is flanged. That’s the side that goes against the spring.
You could put just the arbour in and see how much end play you get. However, I still think that the flange goes in.
I installed a power feed. I used a computer power supply and a small geared down motor rated for 3-24VDC.
Add a few switches and projects boxes and I’ve got an inexpensive power feed.
I can select direction and speed. Speed goes from “pretty ok” on 12V to “really slow” on 5V to “I should have...
I once repaired a platform escarpment on a Smiths ships bell clock.
For some unknown reason, the balance staff had a broken pivot and the impulse jewel was missing.
All I had for a jewel, stolen from another platform, was a little longer and thicker than the original and I couldn’t find the...
Before removing it, I try to find a visual clue as to where to reinstall it.
Is one of the lobe pointing to a pivot hole, a protrusion, any “landmark”?
then I reinstall it by eye as close to where it was and fine tune with the hand bushing.
No, I haven’t tried a lower table, the height is fixed, but my chair is adjustable. I did try a higher chair setting, which helped, but working with my eye glass mounted loupe, meant that I had to be hunched over more, which is a pain in the neck, literally. I already have a bit of a rounded...
