Best way to shrink a pipe

[JimInOz]

I have a seconds hands from a Landeron 51 that seems to be a bit loose.
When I took it off I noticed some "goop" on it, so it may have been "adhered" by something.

Best way to tighten it?

I can use a collect in my lathe and tighten it up......
or
I can try my Seitz jeweling tool with a lantern set, but this is usually for canon pinions (much larger than the pipe on this hand).

Any tips.

I don't know what sort of smutty double entendre you're referencing here, so go to the back of the class and sit in the naughty chair.
You know, the chair with "JWR" carved in the seat.

If you don’t have (or want to buy) a Bergeron hand tightening tool, I’d say the lathe is the next best option. The actual hand tightening tool will compress the pipe all the way around. The lathe collet will crimp it in 3 places in the shape of the collet. It will do a perfectly acceptable job.

I had a look at the Bergeon 3010



So to find a collet. First, measure up.



Then off to the garage to set it up on my lathe.



Hand was held in a No5 collet with surgical tape and given a light "squeeze" by closing the collet.



And then after some light broaching, it pressed on nicely.



And that completes the task.

Actual watch finished here.

The Bergeon tool is really good, but next best is the lathe...
