Do all owners of flintlocks have a mainspring vise for removing the frizzen spring and the mainspring? I am working on a Pedersoli Great Plains Rifle kit and would like to take the hammer and frizzen spring off of the lock plate in order to remove the coloring of the outside of the lock and refinish it with a french gray appearance. I am having trouble finding a mainspring vice and don't really know if I want to buy one since, being new to flintlocks, I don't really know if I will use it much, or ever at all, after this project. Is there a safe and reasonable alternative method/tool that can be used to remove and then replace the frizzen spring? Any and all advice would be appreciated. Thanks.
