Couldn't agree more with trevj. And if it didn't cost a lot of money I'd tell anyone interested in machining to go to college and take a two year course. The info you learn just about simple things like cutting pressure and surface finish etc.. Or GD&T if working for anyone or making parts for anyone other than yourself etc.. Or calculating speeds and feeds are invaluable. Sure you can buy a book and read it and make your way, but if you really want to limit accidents and have decent parts more often taking a course is key. Now I know people who work for a living can't really do this, so sometimes people figuring things out for themselves is just the way it is. I watch a guy on youtube called nyccnc that literally taught himself pretty much how to machine and has a shop now lol.
To bearhunter; I live and work in Northern Ontario, where 80% of the time I make mining parts, some with loose tolerances that allow 0.003, some with tighter tolerances like bearings, or shafts that have bearings go on them and are only a 0.0002 tolerance. I don't claim and never will to be perfect, even with the CNC machines and experience running mine (because many run different.. There are a few of the same make and year in my shop that will move in different directions as they warm up, but you get to know them) they aren't perfect. Regardless of what you read and think you know, it's still an art in it's own form to some degree.
I only get to make parts for my company, one day I really hope to make parts for people for myself. I already have one guy in my shop that has been running the mills for 9 years willing to take on jobs for us if I get a machine. Apparently snowmobile engine modifying is a big thing up here and he is really interested... I really just wish I had the balls to go against my wife and make that investment xD. I have also done many one off jobs in the shop that we get rushed to do for a lot of money that a home shop guy could do for a lot less and still be really happy about. Surprisingly there aren't many around here. (I'm only 29 also, and have only been in the industry for a couple years, but I intend to stick with it and hopefully be that home shop guy one day)
