Clock Repair Courses On Line

I'm going to buy an Ollie Baker style winder. The simple winder Bergeon I have isn't worth the grief.

Apparently, it's a good winder if you know what you you're doing - which I do not - yet.

At least I know the clock will work once I get the thing together again replete with springs.

I use a Ollie and they are very good & solid. The only thing you will have to get used to is the barrel has to be held by hand using a strong thick glove (see pic) Also for safety clamp it solid to a workbench with a G clamp and always wear safety glasses.

I succeeded in putting the spring on the barrel wheel only to find I'd put it on backwards. It was an easy fix. 

The Ollie Baker is easy to use as long as you know what you're doing. ;-)

Question: Are the springs then wound in 2 different directions? (One seems wound clockwise, the other counter clockwise.)

If nothing else it's an interesting hobby.

I have come across striking clocks where one side winds in the opposite direction to the other. 

Just to confuse you even more( ha ha ha) I have come across chiming movements with only two key holes instead of three, the strike and chime wind on the same arbour through a set of winding gears. You will come across all sorts in clocks. :D

    • Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.
    • That's a good idea - shrinking down the nut and wrench size from the old casebook trick!
    • I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.    
    • I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.
