Train Wheels not working.

[WildBill]

Hi, On assembling my 1950s watch... Having trouble with the train wheels, getting the bridge back in position, lining up the 3 wheels was very difficult, same with the pallet fork and the pallet complete,

but eventually I got it done. The watch now is fully assembled. "But not working" no power is,  getting to the train wheels. On unscrewing the train bridge, and prying it up the wheels worked fine and the watch worked. The third wheel top pivot jewel is sitting in it's location wonky....My Question is can I get a new Train Wheel bridge for this old watch, or get a new jewel fitted....I don't have the necessary

tool or skill to do this procedure...Bill.

Perhaps if you can provide information on the calibre, however, it may simply come down to buying a 'for spares and repairs' same movement from ebay and salvaging the bridge.

Have you managed to bend a pivot on the 3rd wheel hence why it is sitting wonky when the bridge is in place?

[WildBill]

There always a chance I bent the pivot, it looks the jewel is not sitting squarely in it socket, but cant see how it's got dislodged

I think I will try and buy a scrapper on ebay and salvage the bridge...It's been a very enjoyable project, my very first attempt to

dismantle a watch  not without hiccups...I think I have the bug....Thanks Bill...

Easiest way to check if the bridge is square is lay it on a mirror or piece of glass and see if you can see any bend in it that way, I doubt that you have bent the bridge during disassembly unless you were really hamfisted mate, there’s usually an answer to why it’s not sitting correctly, you just need to find it, keep trying with the train, I usually hold the movement between finger and thumb and then using an oiler manipulate each wheel in to their respective jewel, starting with the farthest away from the where the balance would sit and making my way to the escape wheel, the one you were having snags with.

in five years I’ve been doing this I’ve only had 2 moves where I’ve managed to drop the train bridge on and every pivot has lined up perfectly!!!!

If the wheel is wonky then it is either bent, broken or the jewel has been dislodged. You will have to strip down again and inspect.

Hi Clockboy, I have found the same watch on ebay, I'm  going to bid for it, if I win the bid my problem will be solved.

thanks for your help...Do you know if there is anywhere I can get tranfers for the watch face, mine came off in the Ultrasonic

cleaner ?.... wont be doing that again....Bill

Ok. If you watch any of Marks vids notice how gentle he is when assembling. Align all the wheels straight and lower the bridge only when the screw holes & pivots are aligned.

[WildBill]

Hi, yeah have watched  Marks videos, it was Mark who gave me the inspiration to try it for myself, I have been very gentle with dismantling the watch, however when I assembled the train wheel bridge before screwing it down holding it with peg wood the wheels

turned freely, after I screw down they still moved freely, but not freely enough for the power source to turn them, so I must have got the third wheel wrong....hopefully I will win the bid on ebay for an identical watch.....

[WildBill]

Hi, It's very rewarding when you see the watch you disassembled, cleaned, assembled, working again.

I had trouble with the 3rd Wheel and the Train wheel bridge...I found a identical replacement watch on ebay its on auction 3 days time.

I thought I would bid for it and use the 2 parts I need...then I remembered I brought 280g of watch part from Cousins, on looking i

found an identical bridge and 3rd wheel, they worked just fine..The watch never work...It's now running nicely. I need to oil the end

stones on the balance, but my oil pin puts on to much oil...need a very small oil pin but don't know what size to buy, do you think

0.75 will be small enough...Thanks for your help....Bill

The smaller size or the one above it, but it's not really about the size but the angle and time you make it touch the stone. You need to practice to get it right and will not get it right every time, just clean and re-do. 

[WildBill]

jdm thanks, I'll have a few practice runs before doing the stone's....
