I'd say that it all depends. If you don't mind a jaw (or several of them) flying out at you
and possibly hitting you in the head or eye, then go for it. If you will always remember
that you must check that it isn't going to happen before you start up the machine, then go
for it. If you are like most of us, it really makes good sense not to disable the safety
measures engineered into the product by the manufacturer.

This Chuck has a travel stop which eliminates the expansion distance. If
this is removed to allow greater expansion, Is it safe to use?

Any comments would be appreciated.

I was told by a Machinist or Machine hobbyist that the Safety was not
nescessary. Hower being the cautious type i thought i would ask advice
here.What are the conditions that would cause jaw or jaws flying out at you.
And if they don,t remove easily with the safety screw removed, then what is
the likely condition that would cause them to fly out?

Keith

I don't know the inner workings of that particular chuck but do know the Oneway products and
also the 3 and 4 jaw chucks found on metal lathes. If you expand the jaws on metal lathes
they will screw right out of the chuck. If you start the lathe and the threads of a jaw have
not caught, it will go flying. I know the same is the case with the jaws on the Oneway
products and assume that the Nova is not much different. As I said, it is up to you -- some
folks get away with leaving the chuck key in the chuck and have never been hurt. I got
yelled at by John Jordan about that so have learned that lesson.

Two things to consider - you can inadvertently expand until the jaws are
free, or you can get them so close that starting/stopping torque or
vibration can free them. The first should be no surprise, the second could
ruin your day if you're in the way.

Either void the warranty.

John sounds like a woodshop instructor I had in college. He drilled into us
to never ever ever leave a chuck key in a drill press chuck or lathe chuck
or to leave a wrench on a shaper spindle. You should hear some of his
stories!

He always insisted that we never relax our grip on a chuck key until it was
lying safely on the bench again.............no matter what. No excuses. No
exceptions. Period. The man was an extremely good instructor, but he had a
hell of a temper. No one wanted to experience his wrath for not following
his rule. I still follow those rules.

PS I still remember the morning a hardwood supplier delivered a semi
truckload of kiln-dried lumber.........on a flat bed trailer...........in
the pouring rain! Let's just say they never did it again!

HS kids can be remarkably obtuse. Self-ejecting keys seemed worth the
expense.

When you consider the issue of span of control in an environment full of
dangers, rigid rules enforced by peers also seem a good idea.
