Just starting to inlet the internals of a lock, for the first time. I read that the sear may need to be shortened to not much more than the centerline of the stock, the trigger centerline essentially. In my case the C/L is 5/8", so I figure I'll trim to 13/16". That is an extra 3/16" for safety, but maybe 1/8" beyond the C/L is plenty. I couldn't find an answer on a basic search here, so please advise. Also, what is the best method to cut the hardened sear. I figured I'd just use a razor wheel on my 4" grinder, using an iced rag to keep the sear reasonably cool. But I'm just guessing.... Thanks in advance, you guys are such a help to my challenging but fun flintlock building endeavors! R Mann
