Currently, I read a lot online about conversions between various firearms, and tweaks and modifications that require some machining, but I know from experience with PCs that the best way to learn this kind of hands-on skill is through practice. For awhile I was way intimidated by ever trying it, but when I was watching this video about converting the HK USC to a UMP and the guy mentioned dremmeling a cut in the mag well to recieve the UMP magazines, I went, "Hey!... I've done dremmel work on PCs. That doesn't sound so hard." Hell, I even got a mini-ITX Socket A board to accept a mobile Athlon Barton processor with a wire-pin mod... Eventually the board crapped out, but that's not the point!

The problem is that gunsmithing as an extension to gun enthusiasm as a hobby is quite expensive, especially for the tinkerer who might screw up, so I can't exactly just start playing around.
Do courses, introductory manuals, or something of the like exist?
