Pig nose or snake eyes or spanner driver help

[Danh]

Hi guys

looking for someone to point me in the direction of tools.

i can not find the sizes of the pig nose screw drivers for watches.

i could just be the search terms I am using from the UK

the description would be 2 holes in the screw head

many thanks

I've never seen screw heads with anything other than slotted screws in Swiss watch movements, although Philips head screws are used in watchcases and Seiko. Maybe this will help?

Yes it's the "spanner" type - I will post a picture later

thank you

Here is a shot of the screw

Ah yes, a pocket watch. I have worked on a few Waltham Elgin and Bulova, but not one like this.

What is the spacing of the holes Dan?

I don't know where you'll find the "right" tool, but there are a number of options...

Searching for TH3 security screwdriver will get you 3.35mm between the outer edges of the holes. TH4 is 4.45

You could try a pair of mini circlip pliers, or a pair of dividers.

You could make your own - take a sort strip of steel, bend over one end and file a slot then round the edges to make 2 pins. Or if you wanted to take the crude approach, 2 tapered clock pins cut to fit snugly in each hole and a pair of pliers.

Hi stuart

about 2.5mm to the centre of the holes, I agree with you, making something may be the answer

thank you for your answer

most appreciated

Managed to do it with a couple of 0.7mm drill bits 

thanks for the help

[noirrac1j]

All that research and the drill bits did it!

Did you ever find out who makes this movement? It looks like FHF???

Since then I have also made / converted a set of needle nose jewellers pliers 

I can not remember the movement - sorry

   there are taper pin stock for pocket watch hinges - about 2 inch long.  vin

This might well work as mentioned by mickey871 above. It isn't all that expensive either.

It is similar - certainly appears to have a design influence

As StuartBaker104 pointed out a similar thread seems to be going on at two places.
I usually use tweezers to unwind the two hole nut in these movements, but for those who isn't comfortable to do so I just tried out another solution. 
Since these nuts appear in movements of different ligne, the distance between the holes will differ. It probably will do between manufacturers too.
The simple solution is to buy a small divider and modify the tips, make the tips flat instead of pointy. This will make them less likely to slipp. Now you have a tool like "one size fits all".

... now why didn't I think of that. By far and away the best suggestion.  Give that man a medal at once.

Excellent - the dividers was one of my suggestions above, but pleased to see it works in practice :-).  I'm sure I have some of those somewhere, so I know where I'll be keeping them when I track them down.
