It looks workable. Very similar to English pattern winders. I like the screw clamp for gripping the end of the spring. I think that's safer than gripping the end with a long nose plier. Make sure that it has serrations for a secure grip.

However, I don't agree with the square bar portion. When the spring in a barrel is wound until the tail can be gripped, it's not going to be tangentially oriented. I think the clamp should be able to rotate to whatever angle the tail of the spring ends up.

But it should work fine for open springs.

Hi Willow  If it comes complete with a set of retainers thats good, whats the postage like.   the retainers alone cost me £60 from America.

About £60 £70 postage and import tax what do you think of winder watchweasol

The only demonstration of a English pattern mainspring winder I can find is this one on a BHI site quite alarming to watch all I can say this man must have the strength of pop eye in his hands note also not a glove in site.

I suggest no emulation of this.

Glad i didn't watch that first, might have put me off taking a spring out and buying a winder

Hi Willow   I would say the winder is ok, also the one posted by Old Hippy will do the job but take into consideration the comments by wls1971 and watch the demo. They were all designed to do a job as was the OlliBaker but all require a gloved hand to hold the spring. The Webster pattern has a clamp for the spring barrel and therefore inherently safer. They are all capable of doing the job as long as the required precautions are taken and used responsibly.

Hi watchweasol just watched the video he makes it look easy but i wouldn't trust myself with one of them i definitley would have lost a finger and he is not wearing gloves,

    • 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. 
    • Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
    • this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.
