THATLAZYMACHINIST | MACHINE SHOP METROLOGY 3, ANGULAR MEASUREMENTS AND GAUGES , Marc L'Ecuyer @THATLAZYMACHINIST | Uploaded November 2018 | Updated October 2024, 3 hours ago.
Third and final part of a series of videos that introduce the novice machinist to metrology (the scientific study of measurement). More specifically, this video introduces us to ANGULAR MEASUREMENTS (ANGLE BLOCS, VERNIER PROTRACTORS), AND MEASURING WITH GAUGES. As for all THATLAZYMACHINIST videos, this video is produced for novice , garage or beginner machinists. You can find all my videos as well as project drawings and course notes on my website thatlazymachinist.com

Thanks for understanding that I am a professional toolmaker and teacher but I am not a professional video producer (and it shows). I produce these videos for fun as a little retirement project that lets me give back a little of what was passed on to me by so many amazing trades people most of whom, sadly, are no longer with us.
