Should I try to repair this dial caliper?
« on: January 20, 2018, 06:09:38 PM »
I picked this out of the garbage recently, and I'm beginning to see why it was there originally.  I thought I might put it across to the intelligent folks here though, as there may still be a way to put it back into service.

The patient is similar to what you'd find here: https://www.amazon.com/001-Graduations-STM-Dial-Caliper/dp/B002D2R3D0

(12" Dial Caliper with 0.001" graduations)

The problem is that the hand is left floating around inside the bezel, and upon closer inspection the tiny centre pinion is broken.  See the attached image of a similar design, where item #17 is the centre pinion.

Now, I'm not a watch maker.  I can work small, but this is perhaps beyond me.  Should I return it to whence it came?

I am not a mechanist - I am a data warehouse specialist. But still I have a plan to make 18 hydraulic rotary vane actuators myself. It is the journey - not the destination that matters.

Definitely give it a try. Especially if it can easily be dismatled. What can You loose ? Some time, perhaps, but then again - it is the journey.
