A ballhone does not cut like conventional stones. You don't need to use 400 grit with them,
Just for info, we do not actually finish hone with 400 stones. We finish the last half thou to size with 280 stones & "plateau" with 3 or 4 strokes with 400 stones with very light pressure.
They do make a 320 or 360, I forget which & it will work just fine. Even 220 will be fine with a ballhone.
Honing oil, light like 10wt oil or even WD 40 works fine for a lubricant.
You need to run the drill fairly slowly to keep a decent crosshatch angle.
It is done when you have a consistent crosshatch looking cylinder that is kind of a matte finish.
Clean the crap out of it with soap & water when you are done & spray & wipe with WD40 or light oil or it will rust instantly as you dry it.
Don't worry about "over-honing", you can spend all day in one cylinder & you ain't gonna measure the amount of material you removed with a ballhone
