Realize, of course, that this is one of my two bong-hit ideas, but I 
wonder what a little thin-walled heat-shrink would do for you if you 
shrunk it over that part of the shaft?

Or liquid plastic?  Or anything that could be brushed on in a thin coat 
that dries hard, but not "rock" hard.  Epoxy or whatever.
