Beginner tool bit grinding Fixture

[Janderso]

my HS shop teacher insisted on us learning it back in '72

I was a Sophomore in High school in 72. Mr. Wade had the same feeling. We had to learn!
My senior year I had three metal shop classes. A TA in one, Advanced and an elective.
Best year I had in that school

Or just don't use HSS and buy carbide tooling. All the geometry is all done for you and you have to understand none of it.

I implore you - don't do this! Being able to grind your own cutters is a super power! Rely on carbide / inserts and you'll forever anguish over certain jobs that are easily resolved with a modicum of grinding skill. Two things that constantly floor me as an HSM: people that cant' grind cutters, and lathe owners that haven't learned how to thread. There's no excuse for being either...

If I'm honest, that bit of my post wasn't entirely serious but more a "throw my hands in the air and give up trying to persuade".

I'm the kind of person who loathes not having at least a basic level of understanding about the basic principles of whatever I'm doing (well, apart from woodwork; if it holds together, is decently functional, and doesn't make people scream and retch in horror, then understanding can kiss my arse! ).

I’m firmly in this camp after decades of relying on carbide for everything.

Why?

Small machines came into my life and at the same time I had to pay for my own tooling.

Even cheap carbide, I’m talking $1 inserts, starts to get pricy vs just touching up the tip of a tool bit.

This is beside the fact that small machines don’t react well to the brute force techniques I was taught in emergency die repair and fabrication.
