Jacot tool and pivot file burnisher question

Recommended Posts

I have been searching for a Jacot tool but I have found  many come without a Bow.

My question is, I can purchase a bow from Cousins but it suggests   "Tie a piece of cotton string form both ends". Is this correct just thinking of its strength etc.

That's what I do with mine - I use strong cotton. You would need to have just enough tension to drive the pulley and no more otherwise the cotton breaks real fast.

Interesting. Have you made one with piano wire - it's a cool idea.

Here you are Mark, ten minutes work. This one is made with 1.6mm piano wire and I slipped a plastic sleeve over it. The ends were shaped cold with round nose pliers then trimmed. I used a very tough upholstery thread to string it and it works a treat. In my earlier post I suggested using 2mm piano wire, but 1.6mm works just fine.

I mentioned this before but I can't remember to whom, but you will usually find a good selection of quality Jacot tools on the eBay.de (German) website. Pickings can be a bit slim in the UK.

 

If you are a BHI member then the annual auction usually throws up some good stuff.

 

If buying through eBay make sure the seller takes close up photos of the lanterns as they are often the first bits to get damaged - a mate of mine got stung in the past this way.

I had the same problem. The tool is in excellent condition apart from that and luckily the seller refunded a large percentage of the cost.

I got burned on two seperate sets with worn and totally unusable lanterns.

Hi Mark,

It was me that you directed to look at ebay.de

And I did find a beautifully complete Steiner Jacot tool that was in near perfect condition for $300US! I remember finding the exact same set on the current manufacturers website for almost $3000.

My only problem was finding a seller that would ship to the US as not many would...

Awesome!

 

I got my Elma Cyclomat from germany and a nice JKA Feintaster.

 

A couple of good searches:

And if you want a great measuring tool:

I just bought one this week from the bay, currently waiting for me at the sorting office, I wasn't going to use a note and just attach to a small motor, or my lathe motor, am I.missing something ?

I know some people attach motors, but to me you will lose the sensitive touch required. Even my lathe which is powered has a safety driver to be used locked in the headstock when using the jacot drum. If something goes wrong when it is motor driven it could be disasterous.

If it was simply for polishing I can understand a motor being used, but for burnishing (work hardening the surface) then think a bow would be the better way.

Just recieved my Jacot.

 

All good apart from the lantern on the smallest of pivots (1-12mm) is missing.have the opportunity to send back or get a partial refund.

 

Im assuming the smallest lantern will be required on balance staffs?

I agree with Geo. The reason I am looking to purchase a Jacot tool is to get more sensitivity which my lathe lacks. I have a foot pedal controller but things can still run away & out of control very quickly if not careful.

Agreed, for pivot polishing you have to feel what you are doing. A motor takes most of your control away.

However, when making a new staff I like to size the final pivot diameter on the Jacot tool and I have often wondered wether what it would turn out like using a motor driven Jacot like a Rollifit - check it out:

Personally I would send that back - it's next to useless.

 

Check this one out - I can't see the lanterns properly but there seems to be spares in the box.

Its being sent back as we speak, its come at a bad time as it seems my Cowells lathe is damaged. So the refund will go to the spindle being fixed now...

    • I think the UK is pretty well known for staid taste, and this ain't that; probably explains some of the reaction. As a woodworker, I can appreciate the use of wood and grain. Even with thousands of dollars in exotic woods stashed in a room in my basement, I have to say it's a bit busy for me for the piece. Some people will dig the natural beauty of it though.
    • I found this is invaluable when searching for that elusive vintage spring. 
    • Here they are mounted.  Since the minute hand uses a bushing, the fit was straightforward.  I printed in black because that is the filament I have loaded. You notice that the upper circle is not open in the print.  That is because of the resolution.  I need to make that hole bigger for it to print properly.  Frankly, the lower one as well.  But, these are temporary anyway.
    • Hi @highflyer In the UK a lot of folk will get parts from Cousins UK. For generic crystals there's https://www.cousinsuk.com/category/acrylic-shaped-watch-glasses for instance. Cousins even has specific Gucci crystals at https://www.cousinsuk.com/category/gucci . However your particular crystal seems somewhat unusual and specific being tall and narrow with rounded corners.  In fact what you're after is https://www.watchmaterial.com/watch-crystal-for-gucci-1500/; also available at https://www.esslinger.com/special-model-watch-crystals/ It might therefore be worth asking Cousins if they can source based on the fact they do other Gucci crystals and if no-one else comes up trumps with a UK source. Failing that you could request one from one of the aforementioned US sites although postage likely to exceed value of crystal unless you can ask for it just to be shoved in an envelope without all the UPS overhead. 😉 If you did take to a watch shop as @watchweasolsuggests clearly it would make sense in this case to get a cost up front; if these crystals are hard to source, and thus incur extra expense, you want to go in with your eyes open.
