Inletting a lock

[Tom]

Thanks guys
This is for a lifter gun and I haven't been able to find a pre inlet stock for it so I'm going to give it a go. At this point I am just learning how to inlet on an old stock so I don't hack up a nice piece of wood. I did order some inletting paste from Brownells but it hasn't arrived. The action and trigger plate went on pretty good but the lock is giving me a hard time. I am trying not to just hack out a bunch of wood behind it until it fits in, but I am finding it difficult to figure out where each part is exactly and just cut out for it.
My thought is strip the plate and inlet that and add each piece inletting as I go. I must admit taking out all those tiny screws and springs that have been happy sitting there for the last 100 years makes me a little nervous. Is that a good plan or is it an over kill ?
Thanks again for the info, Tom
