Hi Folks! I have a problem with the flex-shaft polishing pin kit from
Rio (p.393 in 2004 catalogue) and was wondering if maybe I have a
defective one. I find that the collet doesn’t close tightly on the
pin (2mm) no matter how tightly I close it. You can see the slits of
the 3 teeth aren’t touching. It feels secure when I close it, but it
usually spins right out of the collet as soon as you touch it to the
work. I wanted to cut the slits down lower to put in more
flexibility so the screw part of the collet would screw further down
and fully close it, but obviously a saw can’t get in there because
there are only 3 slits. If other folks are using this potentially
useful tool without this problem, perhaps I just got a lemon…?
