They're not hard to learn. There are no (real) feeds or speeds to set, but you do have to pick a wheel. Operating one is like rubbing your tummy and patting your head, it takes a little practice. Yes it would need another motor (mine uses an old pump motor). Or keep looking, surface grinders are pretty handy. They can be set up for some tool grinding too. The end of endmills for example.
There's also a product known at 4140HT. It's also called half-hard or pre-hard and is between soft and hardened steel. Cut to size and drill some holes.

They sell it in plate, but for some reason I can't get to their pricing today..
