Hi all

I recently bought a Jacot tool and this mysterious part came with it. Can someone tell me what it is? Also is it possible to buy Jacot parts as one of the runners is missing? Thanks.

I am new to this hobby and I know I probably bought this set in haste but I thought I may clean it up and have a go at burnishing. Can anyone also tell me what this runner is for?

This runner is for long pivots - the ones of the 4th wheel, where the sub seconds hand sits.

Ah I see now! Thanks for the hep Nev👍

The only current maker (and for some decades so) is Horia/Steiner. The runners are matched to the tool, so even if you have one with a diameter that corresponds- Steiner runners are 8.80mm- the chances that it lines up correctly are small. The other older tools are often unbranded at all, so finding a matching runner is next to impossible.

Ok thanks Nick. I suppose I need to invest a bit more and get a better set (thankfully I only paid £30). I have access to an engineering facility so may see if I can get something made. Did you recognise the first item that came with it?

Thanks Praezis.

I found this picture online.

Looks like I am a few bits short. I don't recognise it. Would you still say it was a pivot drill?

YouTube the home of tools that are interesting but not necessarily practical.

Yes, it says so on the box as well. It's a "outil á centrer et rapporter les pivots"..

It comes with an assortment of tiny drills and holders for them. Haven't played with it though now I have a lathe, but someday I will..

somewhere in the universe I've seen where someone made a new holder for carbide drills.

That looks a great piece of kit!

Thanks very much for putting me out of my misery 👍.

Sure 😀. You can compare what is missing.

But don‘t grieve, these tools are of little use and I cannot remember someone using it.

Thanks Frank. I think I will confine this to my ever expanding 'non operational tools' drawer...😊 Tony.

    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
