Yay, more questions
Okay, we all know what casters are, I'd imagine. But, today has taught me that I don't really know too much about how they're assembled.
Specifically, what sort of bearing is used at the top of the caster? Y'know, the part that swivels?
What keeps the vertical shaft in place? Why doesn't it just fall out?
Like always, I'm plotting something.
A Caster+ of sorts. But, conventional casters aren't adequate, so I'm looking into building my own. But, umm, I don't know the answers to those questions, so I'm kind of stuck.
I suppose this could be germane to other applications where you've got stuff spinning around a vertical axis.
Help me
Please.
