Yes, get the Chambers info. I have it and it's great for a beginner and maybe an expert as well.
+2 on the Chambers tuning directions.
I too am a long-time owner & shooter, and raw beginner at anything resembling 'smithing MLs. Made a trade for a TC squirrel rifle for The Bride; she wanted it fit, refinished, with lock and triggers tuned.
I referred to Jim Chambers' directions, found in Peter Alexander's book (among many other places), and, found that due to design differences, the TC lock doesn't lend itself to following Mr C's directions step-by-step.
I did happen to have a couple L&R RPL locks on hand for later projects, and as the internals of the RPLs are classic in design, I used them as my "learners". This enabled me to go back to the original project (the TC), and do as much as I could to help that lock out (which turned out to be, not much).
The only real down-side I've encountered is, as I worked at tuning the "modern/improved" TC lock, I (foolishly? wisely?) shared my frustrations with its design limitations with The Bride... who promptly decided that if her current rifle had so many limiting design features, what I really needed to be doing was designing and building her a custom rifle, from ground up.
Point being, prior to beginning these projects, I was in your boat, Polekat: had not a clue which part fit which name.
