Adjustable Scribe Tool - Made in the shed

Speed and feed influence how the chip comes off, but mainly it is tool geometry. For "soft" materials (brass, aluminium etc) a large top rake is best. This will make the chips curl off nicely.

Lovely end result 🤩👍 In the unlikely chance I get to use a lathe again I hope it has one of the digital controller-thingys as it looks to be great fun ! The last lathe I got to use (almost 40 years ago) was the only imperial one in the classroom 🤬 Even worse its scale did not refer to the diameter but to each individual side of the piece so you had to divide the it by 2 every time you made a cut 😭

The DRO had been a game changer. And so cheap! $200 Aussie dollars for the setup. That’s about the equivalent of a weeks worth of broken end mills 🤣

The bird's nest has to do with the geometry of the tool bit grind. You have to cut a chip breaker. Stefan Gotteswinter discusses sharpening tool bits where he covers it. I believe it's in his d-tool grinder video, but I'm not sure.
