Disassembling 10AK 21J movement and am unable to remove the canon pinion. Tried the usual presto tool, then stout tweezer, then pin vise. Won’t budge. Tried watch oil, clock oil, penetrating oil between center wheel and CP and soldering iron to apply heat hoping the oil will travel inside the CP. Have tried several rounds of this for a couple of days. All the tools will slip off while the CP stays put. Pinion is a closed top. Anyone have similar challenge or advice? Thanks.
