Cannon pinion tool

[LittleWatchShop]

I took this idea from "canthus"

Using a 4-40 tap, I put threads in the nail clippers.  Then I printed a knurled knob to attach to a 4-40 screw.  I used a knurled threaded insert is the "tightener" adjacent to the clippers.  Seems to operate as expected.  If I do this again, I will use finer threads (did not have a finer tap on hand).

I,d dull the cutting edge of the clippers so it wouldn't cut into the canon pinion.

Thanks for that wisdom.  I did not think of that!

Brill idea. It must surely work the key is a controlled squeeze and this absolutely gives it. Bergeron beware !!!!!!!!L

A simple but effective tool, better than the wedge stake and a hammer.

Like the knurled knob.  As I said in my post, the lower arm can still flex a bit if squeezed hard against the stop screw.  I had in mind to stiffen up the arms to prevent this but not got round to it yet.

Bergeon haven't contacted me yet!  Soon be available from China no doubt!
