okay so is it normal for a cheap bench grinder to go five minutes after power off? I suspect the answer is yes but that better ones have brakes
but do they? lol idek
(that is with the stones which came with it still attached which adds a lot of momentum)
these stones also do not seem trued, like, they’re snug on the axle and do not move by hand but there’s front to back variance for real. i can true that, right? i mean I’m gonna replace them with a wire wheel and a buffer but I still want to have them for occasional grinding and they clearly should be truer than they are.
@moira A wheel dresser is what you're looking for. There's a "point" style, but you'll likely need the one that looks like loose sprockets on a handle. Much material to remove to get it true...and it makes a mess.
A long spin down shouldn't be a worry, and if the bearings were shot, it would stop quicker! I don't believe a braking mechanism is common, even on high dollar stuff, but I'm not steeped in that side of it.
