Hi, I think that I got this for a good price £20 only. I had to improvise as it has a bit missing. What do you think? Will the paper clip work? I'm planning on sharpening the end of the clip into a more defined point. Any idea why the tool has two sides, is that for different pivot sizes?

The paperclip will work fine, the original part is only used as a visual reference so no real difference. There are many versions of these, usually one side will have female cones with holes going rather deep in the center of the cone, then they are cross drilled. This allows the tool to hold a balance by the conical portion of the pivot, which is strong, and in the event a pivot does break, it can fall out either on its own or be pushed up to the cross drilled part. The other side will often just be simple female cones, but can also be a different size of the cone/drill/cross drill type. Sometimes they are actually male cones. On yours I don't see any cross drilling, but that shouldn't be an issue.

Thanks for the reply. The conical side has very tiny holes and is cross drilled. I assume this side is for finer pivots. The other side, non conical is not cross drilled and has larger holes, I assume for larger pivots. Steve.

You need to get out your files and cutters and make one that’s exactly like the original. This is what I would do…plus it will give you a good reason to buy more tools:)

You are an electrical engineer, not mechanical...BUT...you ARE an engineer...you think like one regardless of the discipline.  I agree...it would be very gratifying to make the replacement part.  I think that is what I would do (also an EE).

Sometimes it is hard to know what is more gratifying...fixing a watch...or making the thing that helps me fix a watch.

Thanks guys, I'm also an electronics engineer by the way. If I can find or buy some suitable steel then I will give that a go. I don't have much in the way of tools but I should be able to hand make something a bit sturdier than a paper clip 🙂

Places to look: old printer (inkjet or laserjet), cassette deck...

I think a dremel tool and a set of precision files (from Home Depot) is all you will need.

Making tools is a NO FAIL adventure usually.

I think you will want to have more than a paper clip if you actually have to adjust your balance.  I recently acquired this one for about $21.50.20240128_2254322.thumb.jpg.c818b503d53bbb4751ede0def37a1abe.jpg20240128_2255052.thumb.jpg.644b9d795fcc2e4ec076ef63c51cf441.jpg20240128_2259262.thumb.jpg.0c91389948eb43f9effe0b948b954589.jpg

Nice tool. Paper clip sharpened to a point has worked very well thanks on a few occasions.

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....

      yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?

      Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
