Firearm Old-School Mass Production

If you like seeing tours of factories and manufacturing lines, then prepare for a treat. Not only does this video show how one of the largest firearm manufacturers produces their stocks, barrels, and actions, but the video is especially interesting because it shows 1960′s era production methods: no bar-fed-lights-out-CNC manufacturing centers… this is almost closer to Ford’s visions.

One of the topics I want write about on this blog is how a formal education and a structured professional workplace are not necessary to invent or create. And, in fact, those things may even slowly strip away the hands-on JUST-DO-IT mentality many engineers posses as inquisitive and resourceful children.
