Crank arm grinds on 19mm profile cranks okay? Or do i need 22mm?

You should be fine. Inb4 odyssey cranks

You can do it, but i highly recommend if you're gonna do them often getting some cranks that are rectangular. They are less likely to flex crack or bend and you can lock in better.

Here is a how to i did with my friends on them. It's mainly me rambling on about nonsense.

looks like my profiles are going on ebay. Wanna get the fit indent 2 piece.

I did crank arm grinds back in roughly 2005 on round arms. I didn't do them like kids do now though. Now kids lock in at an angle with the pedal hitting some, I was straight sideways on the crank arm only, doing them kinda like a boardslide.

I recall playing a kid in BMX because he was being one of those cocky lil brats being a lil turd, so I shut him down with a bar to tire tap, a bar to 540 tire tap, and a crank arm grind across most of a 16 foot long rail. He left and I don't recall seeing him ride much anymore. He started skating last I saw.
