This is a great set of videos from the machine shop at MIT. No CNC Stuff here. I found this to be very helpful, personally. They are from 35-60 mins long and cover a wide variety of tools on a very broad basis. Probably very boring for the experienced users here. I picked up some great tips from this how-to, having very little experience myself. Also makes me wish I had the money to buy some high-end machines. :sigh:
