I am currently messing about with a Chaika 1601 movement which had a very loose cannon pinion (gears turned but hands not moving). I tried nipping it up but managed to mess it up, so it is of no use now. I have got a new unused cannon pinion but it just slips on and has obviously not been crimped (is this normal?). To fit/crimp it to the centrewheel pinion, do I crimp it in situ (I have a tool that will do this) or do I do it away from the pinion (I do not have a core pin that is small or hard enough to fit, so cannot do it off the movement). The movement is from a ladies watch and the cannon pinion is very small with the bore about 0.3mm.
