I would greatly appreciate some input regarding a problem that
occurred suddenly with my flex shaft hand piece.
I have a Grobet hand piece that is essentially a knock off of the
Fordom #30 hand piece that is about two years old.
The other day I was using it and noticed that the burr I was using
was not spinning true.
I thought that I must have dropped the hand piece on my bench with
the burr in the chuck, thus slightly bending the burr out of true. I
tried several other new; never before used burrs with the same
result, therefore I think the problem is in the hand piece rather
than the burrs.
I have tried opening and closing the Jacobs chuck several times and
looking into the chuck for obstructions in the jaws and found
nothing.
I am a hobbyist jeweler/knife maker so I do not subject the hand
piece to the rigors of constant production work.
I am very interested if anyone has hade a similar issue with a hand
piece and if so is it correctible.
I know that this is not a very expensive tool in the grand scheme of
things, and I could easily buy another; but right now I would rather
put my money into finding some very nice ox blood corral.
