Repairing my HP 67 Twins

[jftman]

I have learned some straightening methods doing watch repair. Pivots are very easy to break if Re straightening is tried.

I am not exactly knowledgable of the size and shape of the pins you reference. I myself just bought a HP67 and it isn't working so I want to learn from others!

Watchmaker tweezers come in many types. You might find a solution by getting a pair that are fat and wide jawed. The idea is the extremely flat and parallel tips You would warm them up then let the heat transfer to the work and with this you can straighten stuff.

If you have a hollow pin or ‘cylinder’ a set of pin gauges are handy to insert into the little hole, to not collapse anything. Pin gauge sets for watchmakers are graduated in 0.02 mm typically. Two hundredths of a millimeter.
