The best I've used is the K&D cannon pinion remover. It's now made by Bergeon (well, whoever makes it for them); there was a discussion here a while back and it seems it's really not as good as the old K&D ones. The Bergeon has fewer jaws and doesn't seem to work well with smaller cannon pinions.

 

Here's the way it looks, Bergeon 4854, if you search Ebay or used tool sites the K&D looks the same.

What difference there is between that and gripping in a good old pin vise and pulling strong ?
It doesn't put any tilting side stress on the center wheel shaft, which is a big risk with a pinvice (potential broken center wheel shaft), it pulls straight up. It grabs "just enough". It takes literally 6 seconds to use including taking out and putting back into the drawer. It doesn't leave marks on the canon pinion, which some pinvices may do.

There are cases where it won't work like a split chronograph or minute repeater. There I do use a pinvice, I have one that can't mark the canon pinion.

Nothing wrong with a pinvice, except it is definitely riskier and is slower. I've repivoted a number of center wheels for other watchmakers...

Hi @Nucejoe, @jdm.

Could you kindly recommend us for a good pin vise (size and brand) for use as a general purpose cannon pinion remover? The model in the picture is hard to identify.

Also, how do you prevent marks on the pinion?

 My pin vise must be cheep chinese , has no trade mark or writting on it. Its got fine grip, I have not noticed any scratch marks. 

If your internet works, search for pin vise and do the choosing by images.

To minimize any bending effect, grab the end thats gripping the canon pinion.

      Any tips to correct a sloppy error?

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.

      Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
