Machinists @infosec.pub JillyB @beehaw.org Building Prototypes: a must watch series
Dan Gelbart is a rich Canadian guy who made his millions building machines for other companies. Now he has a money-is-no-object shop to mess around in. I particularly like the video going over his lathe/grinder combo that he designed and built. The spindles and ways are on air bearings and it's incredibly precise. Also check out his video on flexures where he shows off a simple water jet part that allows 25x resolution for you measurements or positioning.

Machinists @infosec.pub demesisx @infosec.pub “TOOL AND DIE MAKING” 1953 NATIONAL TOOL AND DIE MANUFACTURERS ASSOCIATION PROMO FILM XD10964
This 1953 film directed by Matt Farrell for the National Tool and Die Manufacturers Association looks at the importance of tool and die manufacturing for the functioning of American Industry at large. It begins with the contributions that American Industry has made to everyday life and how tools and die were used to manufacture these goods. This is followed by an overview of the apprentice system and some of the skills that toolmakers need to learn such as operation of machinery, meticulous measurement, and reading blueprints. This is followed by footage of the creation and operation of some tools and the development of cutting edge die for the accurate manufacturing of plastics.
0:17 “National Tools and Die Manufacturers Association”, 0:27 “Tool and Die Making – Keystone of Mass Production!”, 0:44 a message about the importance of manufacturing for society, 1:36 shots of modern industrial facilities and machines, 2:20 a machine making razor blades, 3:00 different appliances l

Machinists @infosec.pub demesisx @infosec.pub 9.5" Inch 4140 Gearbox Shaft Part 1 (30:51)
First of a short series of videos about machining a 9 1/2" gearbox shaft. This shaft is very similar to my past Heavy Metal Machining series, so I try and give you guys some different angles, and information I may not have shown before. In this video we get the ends centered, set up in the Pacemaker and begin roughing the shaft down. I have some pretty nice 1/2" metal removal cuts getting the ends turned down.
and Part II here
