On a 24" stand I can see the top whenever I'm seated. Right now they're on barstools and I can see all the exposed top.

On a real stand of course it wouldn't look quite so bad, but it's enough that it wouldn't look right.

I can't imagine it takes too much skill to be handy enough with a grinder... it'd just take a grinder. That is not part of my tool collection. I wonder what they cost...
