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.
