Mainspring Winder Question


Don

Recommended Posts

On Mark's mainspring winder video he winds an automatic mainspring. When winding a regular mainspring with a hook on the end, do you wind it all the way into the winder or do you leave the hook out? Or do you just break the hook off trying, like I did? [emoji26]

Thanks, Don.

Sorry to hear you broke the spring Don, it happens once in a while...I did once too! Although I can't answer your question I would like to suggest -- if you don't have a high mainspring demand/output/business/can't think of the right word here -- to try it by hand. I do all of mine that way. I suppose a winding tool is better but I've never used one.

You have to wind it all the way in otherwise you can't install it into the barrel.

It's very easy to catch the hook (manual wind spring) or bridle (auto) in the entry slot of the winder barrel which makes life difficult.

What you need to do is to stop winding just before the end of the spring enters the winder barrel and then feed it into the winder with tweezers.

No worries, Bob. It was a practice spring. I've tried by hand and with two different types of winders. I'll do some more practice with this one and maybe try hand winding again.. I liked your explanation in another thread about hand winding bringing you closer to the work or something like that.

 

Thanks very much Marc. Exactly the information I needed!

Indeed, as Marc says, wind as far as the hook and then feed it in with some brass tweezers.

 

It is also advisable to remove the tension by turning the crank backwards, maybe two turns. And this is because when you feed in the hook, sometimes the hook will slip all the way around inside, and then back out of the gap and then catch. If you reduce the tension first then this will not happen. If you reduce the tension too much so that you can't push the hook through then you can always crank it up a bit.

 

Hope i'm being clear :)

I'm tooling up to start my BHI distance learning diploma and on advice from forum members will start tinkering with relatively cheap Seiko 7S26 movements. 

Please could you advise me whether I need a mainspring winder and which one?... or point me in the direction of a video showing how it's done by hand please?

 

Many thanks!

Hi Tim,

 

Here's a hand winding video:

 

http://youtu.be/GjZj3XTGTHs

 

I ruined a couple of mainsprings trying to learn how to hand wind and decided I just wasn't good at it. So I bought a set of winders, which took forever to arrive. In the meantime I successfully wound a mainspring by hand and decided it wasn't as big a deal as I'd made it out to be. If you can afford a set of mainspring winders, they will help - especially with automatic springs. If not, you'll probably pick up hand winding faster than I did.

 

Be careful buying old sets from eBay. If the hooks are really worn, they'll be practically useless.

I have been considering purchasing the Bergeon half set of winders. But getting the extra barrels is a problem.

I enquired with Cousins if they could supply specific winders as ad on's for example Rolex & ETA calibers as I had seen them being sold in the USA for  $85

Cousins contacted on my behalf Bergeon who stated that these specific winders where at present not in their catalog but will be in the future & therefore will be eventually for sale at Cousins.

Also the winders that are being sold by the USA supply houses are not Bergeon but will probably work with the Bergeon winders.

Many thanks Don,

I'll take a look, then practice practice practice.

 

You're very welcome. Actually, the hardest part is getting it started, because of the recurve of the barrel end of the spring.

 

As you know if you read my original post, I managed to make using the mainspring winders difficult too. :rolleyes:

Interesting. Ofrei in the U.S. has individual drums and arbors listed on their website. Some say Bergeon and some do not. I inquired about ordering individual barrels and arbors. At first they said it was a backorder and then they said they were out of production. ???

Don, it was Offrei that Cousins contacted and the reply was that they are not Bergeon but should work with a Bergeon winder.

It was just me trying to save some money. The full set kit is £800 & half set £400 so me thinks that buy the half set & add to it as required but this seems difficult.

My present winder has worked great until I tackled a Rolex & it was not up to the task. It is a lot of money to spend but as the saying goes "you only get what you pay for"

I see. None of the Rolex specific sizes says Bergeon, but the individual barrels and arbors of the standard sizes are Bergeon.

 

I was thinking the same about saving money. The half set is an extravagance for a beginning hobbyist, but I ordered that and the next two sizes of barrels and arbors. They sent the half set and some combination of the barrels and arbors, but said the rest were out of production. Also, the 5355 set only has sizes 0 to 6. I'd probably seldom if ever use the smaller sizes and I'll probably need higher than size 6. So I had my wife leave the room and I ordered the full set. I'll either use them the rest of my life or I can always sell them and get a good chunk of the money back. It's a shame they can't be bought individually. Mark wrote in another post that he mostly used sizes 4-9.

Don, I have been considering the same BUT a lot of money. I am still tempted to purchase the half set & purchase one of the Offrei ones to see if it works.The problem is there are no real bargains any more on eBay & it's going to be a very expensive test.

 

Wondering if Bergeon are scaling down on their production of tools. They no longer make a Platex tool & now looks like they don't make some of the barrels & arbours. Worrying times for pro,s & hobbyists.

    • Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
    • just one little minor reminder here this isn't your normal balance wheel.  pages 17 and 18 are what you really want to be looking at. normally studs don't turn but this watch has the etachron system designed for lots of adjustment. Personally I would try to rotate the stud back to where it's supposed to be. If you're lucky you didn't actually bend it at the stud it just looks really bad as the stud has been rotated grossly out of position.. I think things will look a lot better if you put the hairspring back where it's supposed to be by rotating the stud. it's hard to tell if you actually did bend it at the stud or not we won't know until you rotate the stud back more or less where it's supposed to be. Then you want to pay attention to the manual of how to put the hairspring back in the regulator pins because yes they rotate also and they rotated specific directions otherwise bad things will happen to your hairspring. so initially you can open up the regulator as wide as it can go and don't worry about closing it until thing everything is right then you can close them a little bit
    • I need to see photos of the whole movement before I comment. 
    • Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed. 
    • Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank
