I have just stumbled across this; http://techtv.mit.edu/collections/ehs-videos/videos
They are instructional videos teaching MIT students how to use the machine shop. There are some great tips and tricks in there for people like me who have had no instruction. I didnt even know what a wheel-dresser was until a few hours ago
I haven't visited this site in quite a while so it may have already been posted... but I saw this and thought of you
