Mainspring Winder Issues

I have used various mainspring winders + the bergeon winder & just lately always the same issue, the arbours are too fat for modern springs. I found by adding a tiny amount of Vaseline to the arbour after loading the spring onto the arbour helps with the release.

However this still does not always work & I am wondering if I could modify the winding part of the Bergeon,perhaps by cutting inspection slots on their sides.
Any thoughts much appreciated

Yes I also have this problem, so far I just wind the mainspring into the barrel when I don't have the right winder, maybe you do the same? Also I use pliers to manipulate the core of the mainspring to fit sometimes. Good luck, and post anything u try, I'm very curious.

I have started to use the wrong arbours with a cheap winder set I have (see pic) but because of the thinner shafts they release but it,s a bit fiddly & can go terribly wrong if not careful. A bit annoyed because I spent a lot of money on the bergeon winder set & at present I can not trust it.

Really interested in this topic. A friend of mine has a brand new small Bergeon set (eta) sells on cousins for approx £595.

It's the 2795eta set 4e4774638f90559832df4ff5113c9692.jpg

It's unused & still has some of the wrapping on it. He purchased it when he was setting up shop a few yrs back. However, he states that he prefers to hand wind mainsprings as he gets more satisfaction this way. Anyway, he's offered it to me for £200 & TBH I was going to buy it. But after reading this I'm not sure it's worth it. I'll be watching this carefully just to see what others post.

I'm not sure which springs you're winding but I work mainly on 50s and 60s watches where the winders work well.

After winding into the tool, I wind the arbor backwards a few turns and that should get the hook off the spring. Then, I slowly lift the arbor piece out, looking to see if the spring is free which it often isn't as it's gripping on the arbor by friction. So, lift up a few mm, slide a brass tweezer in and hold the spring against the handle side while lifting off a little more. And so on.

This works for me, if that helps. There are specific winders for some ETA calibres but I've not seen them so can't say if the arbor is a smaller diameter.

Cheers, Chris

Hi all,

I am kind of facing the same issue at the moment. I got a vintage ("Bergeon Style") winder set (it is marked "GB" and looks like Bergeon, but no idea if it really is, there was no box) on Ebay and if I pick the right size winding barrel, the arbor will be so fat that I can not get the spring off of it once I have wound it in. Usually it all explodes into my face at some point (and yes I got safety glasses just in case).

If on the other hand I choose the correct size arbor, the "washer" that closes the barrel will be way too small and the spring will not stay in (and it again explodes into my face).

So has anyone found a workable solution for this? My current idea is to get a metal or plastic washer the hole of which would be the exact size of the existing "washer" over the arbor part of the winder and that way extend the overall arbor washer size. But I have not tested that yet. Do you think that could work?

Greetings from Luxembourg,

Olivier

I use a tiny amount of grease on the arbour before the winding. Then when releasing make sure it has released then on move the arbour out a fraction so you can insert a vey thin pair of tweezers and just push the centre of the spring down then repeat the procedure a bit at a time until the spring is finally fully released.

No need to remove providing you have used only a tiny smear - the ideal grease would be mainspring grease. I used to use Vaseline. It only effects the very inside of the Spring so does not effect the operation of the Spring it just makes it easier for the Spring to slide on the arbour

      Black coating on shock jewel metal housing

      That was my gut feeling as indicated in my previous post. The total time in water is 15 minutes which seems too long. I go half that time at room temperature. I go six minutes of cleaning in Elma Red 1:9, less than two minutes of rinsing in battery water, and about two minutes in IPA. Depending on how dirty the movement is I get a fairly good result. For a near-perfect result, I need to pre-clean the parts by brushing them off in a degreaser and then in some IPA.

      Yes, the screw seems to be forced in the smaller hole. In such case the screws will not unscrew when drilled with reverse drill bit. You option is to dissolve it. And yes, it is possible to drill a hole in it, then to press tappered broach in and try to unscrew, but it is much harder way.

      First Project Already A Bit "Sideways"

      So that is what the last person to work on this movement appears to have done.  There was a "wad" of adhesive material in the vicinity of that hole when I took the dial off.  I was hoping to take the high road and fix the issue in the work I did on this movement. I wasn't sure if I was imagining things or not when I looked at the screw hole, but it does appear to be somewhat distended.  I had not considered the posibility that someone had forced a screw that too big in there.  I had wondered about using a technique I've applied in other applications (where the screws are in the same scale as human hands) that involves counter drilling the plug with a  reverse threaded tap.  When I've had to do that in the past, the screw has generally caught and backed out from the torque on the tap (instead of yielding and letting the tap bore into it.)  I don't like doing that, but it's saved my rear a couple of times, but the smallest bolt I've tried that on had a 5 mm head.  This is an entirely different ball of wax. I am still contemplating disolving the screw with alum, even if that means I have to stick the dial down with double sided tape until I gain the skills to actually replace the screw.

      Balance staff sourcing?

      Hi Thomas, you should be able to find the right (or on close to beeing) in a Ronda or DCN balance staff catalogue. Cousins uk have those available as a download.
