"The main thing is to learn about what you need to do and how to do it, then to do it carefully" quote.
And slowly. I re-install and check my work a lot while doing trigger jobs. As the old saying goes.....it's easy to take metal off, but damn impossible to put it back. I learned that on a Redhawk a long time ago. Holds especially true on rifle triggers.
I did a Savage several years back, pre-Accutrigger, about 8 hours with a very fine stone and super fine adjustments on the screws. Ended up with a 2# trigger that broke like glass and wouldn't trip when bounced on the floor.
Slow and steady with minimal material removal along with reassembly is the way to go.
