Repair Loose Hand

[danizzz]

Another noob question from me!

How can you repair a loose hand, the second hand in particular?

What's your technique? Do you use a particular instrument?

If the hand is okay. It's easy to just put it back in the pivot and press with a toothpick. That is actually what i use most of the time. Press in the middle. Some movement may need to have the pinion to be  supported on the opposite side.

I would put the hand onto a watch reamer and pinch it a little. I found this to be most satisfactory.

I've done this myself, it's always safer to support from within when squeezing a tube.

Yes with all repairs you should be very careful.  Do not pinch it to hard or you might change the shape of the pipe.

Which reamer do you guys use for this kind of work?

[oldhippy]

You need one that fits through the hand then pinch it lightly in the middle of the pipe, do not use force but gently does it.

I should have added if the cannon pinion is the closed end type, find a reamer that will fit in as far as possible then pinch.

I'm guessing you probably don't have one, but just for the record:

The proper way of tightening hands that don't grip the pinion/canon properly is with a staking set. Not sure if I'm going to be able to explain this in a way that makes sense, but for those that have them, look for the stake that is appropriately sized with an open, inward incline these are used to push the gripping tube section of the hand evenly together with a light tap, hand facing bottom side up. 

It's explained and illustrated somewhere in 'the staking set and how to use it' there's a .pdf but it apparently doesn't have that page. 

Never tried to use a reamer and pinching it, but it sounds like it would work.
