Just a comment, and I don't mean to sound pretentious or arrogant, or anything; and I know it's not possible for everyone. But, I think about th= e hundreds of hours I've spent over the past 40 years flailing away at bits o= f metal and plastic with files, hacksaws and various implements of destruction... and I can't believe I didn't buy a mill and lathe sooner.
