Gear shaft re install

[bonusbuilt1950]

This is from a 1942 Westclox Pocket Ben and when I disassembled it, the shaft came out with the second hand. I cleaned all the parts and removed the second hand off this shaft. I am planning on a tiny bit of red locktite to hold it in place once I get it back in. My question is, How can I get this back in place? Any special tool needed to do this? I tried tweezers, but you can't get a firm grip on it. Pliers would be too rough on it. I know the easiest way would be to get a parts watch, but hate to rip apart another watch for one piece.

Hi bonusbuilt1950,

How can I get this back in place?

Have you got a small pin vice?

That I don't have.

Forgive my ignorance, but I am new to this. Is what is in the pic a pin vise. I bought a bag with 3 of these of similar design and thought they were tiny screwdrivers . They had some tiny tips that look like a screwdriver tip. The smallest one is a 0.14mm diameter and the actual pin I need to put in is 0.10mm diameter. It has a set screw near the end. I'd be afraid it might bend the pin if it is real tight. It has Bergeon 80 stamped in it. Look at the pic and tell me if it is a pin vise or a tiny screwdriver. Again, sorry for my ignorance.

Those are screwdrivers.

Those are screwdrivers.

I thought they were, but I'm no expert.

Yes they are screwdriverd however, some screwdrivers has a collet type fastner i.e. no screw but a tip where you turn to tighten the screw driver bit.

I guess you could use one of those of the right size as a pin vise for your purpose.

In your picture the four top screwdrivers looks like this type.

Hi bonusbuilt1950,

These little tools are invaluable for all sorts of tasks, and they aren't expensive if you look on eBay or other sites, you don't need to pay Bergeon prices!

I plan on getting some. I looked under used ones, but none of the sellers have sizes in their listings. Plus, they're more than new ones. Alot are Chinese or from Singapore. I see Chinese Bergeon ones for around $20usd. I need one that goes down to 0mm. My shaft size is 0.10mm.

If you don't have a pin vise you can try inserting shaft into a screwdriver and use it like a pin vise. Not sure it it will work but worth a try.

Hi bonusbuilt1950,

My shaft size is 0.10mm

Are you sure about that measurement? It's just under 4 thou which is finer than any pocket watch pivot I can think of.

Graham

 

[Skutt50]

Agree with Graham, it seems very narrow.

I can't stop thinking this is a re-pivoting job where the bearing is actually part of what is left with the pinion and the loose part is a pin fitted just for holding the seconds hand.

The pin goes thru the plates on both sides. One side sticks out farther for the second hand. The actual holes in the plates are pretty small. I could be wrong, I'm new at this. I'll check it out again.

 

[bonusbuilt1950]

You likely meant 1mm?

No. I measured it again and it is 0.40mm

Re measured it and it's 0.40mm. I don't have to worry as it took off after I had it in the gear part way. My floor eats small stuff. Spent a long time looking for it with no success. It will turn up after I have the job done. Lol!! Look at The gear and see the little center pin

 

[bonusbuilt1950]

If you look at the plates, you can see where there is a slight in dentation where the bottom or top of the gear sits and the pin I'm talking about, go in. I had the pin part way into the gear and when I took the tool off, it took off tp parts unknown. I had a Pocket Ben version of the Scotty, so I robbed it and will use that. Should have done it in the first place. Live and learn!

The pin goes thru the plates on both sides. One side sticks out farther for the second hand.

My thought was that someone broke the part where the seconds hand is attached. To fix they drilled a hole through the entire pinion part and inserted the pin you just lost. There seems to be some solder on the pinion which could have been from an attempt to fasten the pin. Since you have a replacement part you could check what it looks like.

One other way to try to fi this could be to cut a small piece of a guitarr string. I don't know the string dimmensions but there might be one that is ,4 mm.............

My floor eats small stuff.

Magnets are good at attracting steel parts. If put in a plastic bag it is easy to rinse. I keep a few neodyn magnets handy close to my work station. Also a vacum cleaner with a thin sock over the nossil will dig up parts lost over time.....
