Yep. Exception made for chair casters, unless they're above average, I don't let many casters. I only had two of those and had to hoard them for at least twenty years, until I found a good use for one.  Now, I'm back to an unmatched single (sniff).

Splinter, it seems I can run anywhere from around 5, give or take three, to 15, the latter not seeming to pose much of a slinging problem.

Faster might be better for striping things. 

The paint turning probably ended up on the street. It was a test to see if I could become an expert at pin striping a cylinder of sorts.
