Well that has to be one of the ten stupidest things I ever seen on
Usenet.

The knowledge skills required to safely operate a lathe are
significantly
different from those required for flying or driving. People who are
highly
competent as pilots may still not know a damned thing about lathes.

Forbid anyone from using the lathe unless
they have verifiable training and use manufacturer recommended safeguards.

OTOH, that is a smart statement.


There are risks inherent in almost anything. People are hurt using
screwdrivers, electric drills, power saws and shears.

Yes, that is why people need to be taught about those things, just like
they need to be taught how to fly. Some of the hazards are not
obvious.


If it still is a concern, limit the use to adults and then have them sign an
appropriate release.

Obviously, THAT should be done, no 'if anything'.

In addition, you probably should already have some
liability insurance. The dangers from a lathe are much less than a rotating
propeller. I suspect more injuries occur using a drill press than a lathe.


People seldom work as close to a lathe as they do a propellor, they
typically are not trying to see what is going on close to the hub.

You are probably right about the drill press vs the lathe because many
more people use a drill press. OTOH I'll bet the typical lathe injury
is worse than the typical drill press injury.
