Part one of a two part series on making 3 each of 2 different indexable insert cartridges. Lots of surface grinder setups and procedure discussion. A focus on how removing material by grinding can be faster than milling because of magnetic work holding methods. Great video synopsis by brs_workshop "Shop Notes"* • Talks about shop visit from Tom Lipton • Quick overview of the videos and reveals the motive of the video: surface grinder as a metal removal machine • Reviews the drawing. If Robin's dirty hands bother you, the smudges on the drawing will really get you going ;) • Explains thought process of machining and grinding a complex shape. • Stoning the Rollin saw to prevent damage from hardened A2 • Starrett blade referenced is an Intenss PRO 3/4" x .035" x4-6/p Amazon (Intenss PRO): https://www.amazon.com/Starrett-Intenss-Bimetal-Positive-Length/dp/B004R9Q09A/ KBC Tool (only have 5-8 and up): https://www.kbctools.com/products/CUTTING%20TOOLS/SAW%20BLADES/BAND%20SAW%20BLADES/4019.aspx Starrett website: http://www.starrett.com/saws/saws-hand-tool-products/band-saw-blades/bi-metal/intenss-pro#Products I am suspicious McMasterCarr also carries these and simply isn't branding them: https://www.mcmaster.com/#band-saw-blades/=19vlvj1 They also make the Intess PRO-DIE which is basically the same but with smaller blade depths for tighter radii and small machines.

These are from Brown and Sharp but imports are also made. There are two widths but B&S; only seems to make the thinner ones.
