Good evening. Sadly, the English tallcase movement I'm playing with seems to have been hiding a pretty disappointing missing pinion leaf on the gear that trips the bell hammer -- I can see some porosity and crystallization --- perhaps the spring was made too strong on the hammer, and some backlash cracked this leaf free some time ago. (disappointing cartoon sound effect) ---- anyway -- does anyone have a good method of solving this, short of a complete re-cut, which is beyond my skill level. Any advice would be helpful. Thanks in advance.
