I posted up a few other types a couple of hours ago, have a look and give me your thoughts. So unscrew the long handle fully which it isn't in the pic press the button at the bottom which opens up the clamp. Insert a dial hand into the appropriate hole that fits the hand then screw the handle back down to tighten the clamp. Once the hand is secure in the clamp and is centered within a clamp hole you can broach through the clamp to increase the hand hole diameter .

I have unscrewed the pieces as you described but do not understand what constitutes the "clamp". I saw the tooling on the side and thought that the band between opened, yet if it does I am unable to get them apart. Thoughts?

Update: The plates "popped" apart and there seems to be some sort of mastic that stuck them together. Will assume the same holds for the smaller of the two and soak that and clean it before forcing anything. Many thanks.... much appreciated.....

The clamp is the 2 plates. If you unscrew the handle fully, the 2 plates will seperate.

`Don't think of this as a hand holder only. Is used any time you need to  hold anything flat and open up the hole in it.

Then pictures might help complements of the Internet.

But let me read the description first

Yes this is a really interesting description isn't it.  So you unscrew part of it then you squeeze like shown in the image and it opens up. It is a spraying keeping it together. Once you get your item where you'd like it to be then you can tighten it back up and be careful when you're holding it not to break off the hand that sticking out typically

It should look like this with the top handle unscrewed, now press the button at the bottom and the handle, the clamp plates will seperate.

Found another picture online you can see the hand in the holder. You'll see the smoothing broach and you can see the protruding hand that I warned you about because of you not careful you end up breaking your hand off..

Breaking "your hand off" would be really painful.  Hehe.

This tool is actually my favourite for broaching hands. The spring loaded action of the moving plate means the hand is positioned and quickly held by releasing, if you need to adjust the hand slightly to center it in the broaching hole gentle squeeze the tool together to off the tension slightly. When the hand is lined up where you want it screw the main handle back down to secure it. This tool is a bit less faffy than the old pliers, they run at around a tenner. A good stash of nos or just old hands, a set of smoothing broaches and you are away fixing those missing hand watch. I found as an average being able to increase an hour hand hole by as much as 0.25mm a minute hand by 0.15mm depending on the tube thickness or end plate of the hand. Obviously a blind hole tube requires a different idea.

Just another tool to look at. Until you need to do the job that tool does, then it's not just another tool.

I had to make the hole in a minute hand larger. Only option was the riveting stake block. That was hard work for a beginner. Could have done with the looked at tool. Ah well.

Ross you can get these from Cousins for just £7 (not one of the usual £££ Bergeon tools 🤣)

It's a useful tool - I use it for holding all sorts of small parts

But you managed to do it Ross, that's the point and thats why you are still here buddy because you have initiative and ingenuity. The vice just makes it easier, lots of us here buy nigh on scrappers with hands missing, so its a great little device for helping with that.

Dont forget Mike Ross has a staking set coming that has wiped his budget out for the next few months 😉. That will help to close the hand holes back up when you've over broached them 😉

I have some pending expenditure. Just used my jewelling tool to ream a hole and push a jewel in - which shattered. Odd, so I measured the 0.99mm reamer. It's only 0.97mm, which obviously isn't enough. I measured all the other reamers, and they are almost all 0.02 to 0.03mm too small. As they are hardened steel reaming brass, I don't see why they should have worn so much.  I'll just buy one at a time as I need them. Can't find any on AliExpress.

What J tool do you have ?

I didn't know until recently when someone posted this site which lists horological trade marks. https://www.mikrolisk.de/

Turns out the "P" means Henri Picard & Freres.  The standard 2.35mm reamers fit, so I can get them from Cousins

Same size as the Star and seitz reamers, the ones that are undersize are they still sharp?

Not very, they look like they've had a useful life.

The reduction is probably due to losing that cutting edge. I think most reamers have a relief on the backside of the front cutting edge rotating clockwise . Just wondering if you could add a relief to the opposite edge to get more use from them. I'm fairly sure the only difference between the edges is the back relief.

Sounds a plan, but how would you do it ?

The problem is that I need a larger diameter than is there. I suppose you could down-size them. So grind the 1.09mm down to 0.99mm etc.

I dont think that is possible with the equipment we have as there is the taper to take into account. I understand what you are thinking, but i mean cutting in reverse could give you bigger hole. We had a discussion a few months back after someone had made a pivot gauge.  They experienced a wobble of the plate while they were cutting the holes, apparently an effect of the reamer design. Just by having a cutting edge as opposed to a blunt edge could give you that extra 0.02mm. Just a thought

How? The base of the reamer is the maximum diameter of the hole. If it has worn away I can't see how you can make the diameter larger?

I'm not entirely sure, its a bit hard to explain how the reamers cut and may not apply to end section of the reamer I'll try to find the thread. Somethings are just worth a try.

    • Hi Bob, Welcome to the forum and thank you for your service.  I would never try to discourage you from getting into this wonderful hobby/profession, but please be aware, it does not cost just a few dollars to get into watch repair.  Tools are expensive and in many instances the cheap knockoffs are worthless, especially when learning.  You can get the tools needed to disassemble, clean, inspect, reassemble and lubricate a watch without spending thousands, but as soon as you start getting into task-specific tools, there are so many and they don’t come cheap.  My suggestion is to start with the basics required to disassemble, clean, inspect, reassemble and lubricate only, and build upon that gradually as the need for other tools arises.  The advice above regarding starting out on working movements is gold. Many of the non-running watches on eBay have been bought, tinkered with, deemed too difficult and then sold again, often with more damage done each time.  Without experience, you clean and service a non-runner and it still doesn’t run. What now? Troubleshooting is difficult as a beginner. This can become very frustrating.  I would encourage you to buy a working movement, and learn to strip and service it. If it isn’t running afterwards, you know it’s down to you, and as long as you didn’t damage anything you know that the parts you’ve got can form a ticking watch. An excellent movement to start with is the ETA 6497 clones from China, such as the ST36. They’re not expensive, and although it finds use in some larger wristwatches, this movement was originally designed for use in pocket watches, so everything is larger and easier to see and handle.  Once you can service a new ST36 and have it running better than it did when it arrived, you’re definitely ready to step up to working vintage watches and then think about repair of non running or poorly running watches.  As far as cleaning solutions go, you will not do better than the commercial watch cleaning and rinsing solutions that are available. You’ll find plenty of suggestions for home brew cleaners online, but the professional products are superior and you want to give yourself every advantage you can, especially when you start working on vintage movements containing hardened decomposed lubricants and often years worth of other dirt and dust. Alcohol is ok for cleaning or rinsing movement parts that don’t contain any shellac. The pallet fork and roller table contain jewels secured with shellac and will tolerate a rinse in alcohol but not prolonged exposure. Methanol dissolves shellac faster than ethanol, and isopropyl alcohol dissolves shellac slower than ethanol. Just in case you don’t know already, the radium on the dial (and likely the hands) of your Dad’s Elgin is highly radioactive. It is safe enough when safely contained within the watch case, but the moment you open the watch and especially when handling the dial or hands you must take precautions against inhaling or ingesting any radium.  Best Regards, Mark
    • I have both sets and use the K&D 99% of the time.  Yes, you have to be careful with the pin.  I use a screwdriver to carefully release the pin from the spring.  Some skill is involved.   I have also modified/replaced the pins in the arbors as necessary.  Yeah, you would think a tool would not require modification, but such is the world of watchmaking.  There is no perfect tool.  Each watchmaker must the tools to his skill, or vice versa.
    • I have the 8-11mm K&D but it doesn't do a great job with modern mainsprings, or I have had terrible luck. The arbor pin protrudes too much and I have damaged more springs trying to disengage the arbor than I have successfully wound and inserted. It seems easier to use with old carbon steel springs. My Watchctaft set gets far more use, though I have to get creative to wind left hand springs
    • It depends on what the gaskets are made from but silicone lubricant should work.  Spray or rub on a generous amount, put in a sealed bag and wait a couple of days.  Test for softness and wipe off the excess.  
    • For hardened gaskets, an experienced watchmaker told me he usually found heat to be the best to soften them up. I tried that on a '70's Tissot where the gasket had turned to essentially epoxy to no avail, but eventually got it off with a 5700 case back opener using a crowbar for leverage to turn the wheel.
