I made a thing! Based on the designs of Chris of Clickspring, and Quinn of Blondihacks. One simple scribe. Solid brass body with a needle for the tip.
Learnt loads. Esp that I need better inserts for brass, the surface finish is... suboptimal. I may attack it with some emery paper later.
@dequbed Oh yes, I was just using what ever inserts were in the makerspace lathe tool holders.
@quixoticgeek Yeah absolutely not judging, you use what you have on hand. If you like the idea of grinding your own lathe tools though you could go get yourself some HSS and grind your own cutters ^^
@dequbed Yeah, I'm actually wondering if I can get inserts that are designed for brass to go with the holders we have...
@quixoticgeek Few inserts are specifically designed for one special material, but you can certainly find inserts that fit your holders that have other geometries
@quixoticgeek if you only can find ones that are designated "for <material>", cast iron and titanium are usually also cut with small or neutral rake angles, so those will probably work
@dequbed For now I am thinking of it as textured for extra grip... :p
@quixoticgeek … textured for her pleasure
@quixoticgeek Ooooh, that looks like it was cut with a positive rake angle, brass cuts *so* much better with a negative one ^^'
