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.
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.
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 🤣
I've been a Toolmaker for 35 years. their my calipers, Ill use them as I please.
Ha! Good on you 🤗
