Well said Antonio. Its amazing the amount of people out there who have zero skills, don't work at a trade/craft, are not metal workers, probably could not bang a nail into the wall straight or change a sparkplug in their car, yet they decide they can precision build a firearm and jump into a project head-long and i would imagine once the initial gusto disappears so does the project.
I served an apprenticeship and work as a fitter, i don't think its a trade that exists in America, but i could be mistaken in that. The first year of my apprenticeship was filing metal parts to fit each other to a tolerance of 0.02mm, and often better. You had to reach a satisfactory level of work before you could progress to milling machine work.
I did make a breech block for a Westley richards falling block a few years ago. Nothing particularly difficult, but it took the best part of two days to get it right. So i know not to rush into projects blind.
