Skutt50, that sounds like a good solution, thanks! Of course, I will have to acquire a left handed tap and die set of the right size.
Jerry, the movement is mine. Thanks for the suggestion and drawing! I shall mull over this, since it's mine and there is no time pressure :-)
Graham, this is...
So I carefully milled the mushroomed head of the arbor, happy to inform that the wheel suffered no collateral damage :)
The threads in the wheel aappear to be intact, those on the arbor are all but gone. I will think about what to do with this. A threaded assembly is likely to fail again...
Jerry, Dewey and Karl,
Thanks for your help. I tried unscrewing the wheel from the arbor but it turns both ways. I think the thread gave up at some point and somebody tried riveting the arbor to the wheel. The end of the arbor does look a little untidy. I'm going to put on my thinking cap. At...
I got this movement recently because it intrigued me. The dial is held down by screws and I found the "Lepine" layout unusual for an English watch.
The trouble is, I just cannot figure out how to dismantle the barrel. The ratchet wheel is secured to the barrel arbor on the dial...
This is my J W Benson Ludgate watch. The mainspring needs to be replaced.
The one that came in the watch is as follows-
2.1mm X 0.15mm X 550mm
Another, similar junk movement has a different size mainspring-
2.6mm X .02mm X 550mm
Here are the internal dimensions of the barrel-...
Hello again Graham,
There's no markings anywhere, apart from the serial numbers and 'reversing pinion' on the barrel bridge. Its got a club foot escape wheel, if that helps, and I'm quite sure the beat rate is 18000.
This is such an informative thread, thanks everyone for sharing your knowledge. Graham, do you always change the mainsprings in the Verges/cylinders/levers? Thanks in advance for the help.
I am in a bit of a hurry now. No time to study the Smith or watch the videos I mentioned again. All the same, I found them and here they are-
I see your point. However, I feel if the power loss/friction is constant and repetitive over a small interval it could be tuned out. Of course, George Daniels wrote that the remontoir is too much trouble to make for something that can be fixed by other means :-)
Many years ago I watched youtube videos of a home made remontoir on a skeleton 6497. The remontoir spring was between the fourth wheel and its pinion, sort of like a balance spring. In addition, the extended pivot of the fourth pinion had a wheel attached to it on the dial side. This wheel had...
Well, I live in India and we do not have a rich watchmaking or watch repair tradition here. So, used tools (what a person on a budget looks for) are virtually impossible to come by. Many years ago I bought a Wolf Jahn turns from someone in the US. It only had large female runners so I made the...
Over the years I have made and collected the tools required for this delicate operation. Last week I decided to take the plunge.
In the picture below you can see the balance with the balance spring and roller table removed. The old staff is on the balance and you can also see a balance staff...
