Lathe, drillpress, milling machine available, but.....

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

Speaking as an old Jr. High Shop teacher, I suspect you are right about the
drill press.
Especially when attempting to drill sheet metal. If not securely retained
sheet metal instantaneously becomes a rotating blade when the bit grabs, as
it often does. Some of my
60s longhairs also learned they needed to restrain their flowing locks when
working near
rotating machinery. I had to constantly preach on that point. No total
scalpings ever occurred, but it was a constant worry and a few small
floating locks were removed.

With lathes I remember a major hazard was ties when someone would
flip his over his shoulder or tuck it into his apron instead of removing
it.

Then you have forgetting the chuck key in the chuck (duck!)

Next, cutting too much material at once resulting in a broken cutting
tool (crack!), an ugly workpiece, and a lesson learned... which is also
why one wears eye protection.


Serious suggestion:

Maybe you (the original poster) could run a hands-on demo at the next
chapter meeting. If you could make even a small number of people (three
or four?) not afraid to use it that might do the trick. Who here admits
to experiencing, as a builder, fear of the unknown, be it tools,
welding, metal wood, glass/composite, etc, on at least one occasion? I
admit it.

I have a serious suggestion to solve that problem. I am a shop (carpentry)
teacher, and it is convenient, impossible to loose a key, and safe.

Tape (or buy a holder) the chuck key to the power cord, about a foot from
the plug.

You have to unplug the drill while changing bits. (good idea)
You keep from misplacing the chuck key (a good thing)
You never will turn on the drill press with the chuck key in the drill. (a
very good thing)

My drill press has a foot momentary contact switch on it. When I was
cutting out the lightening holes in the wing ribs for my RV-6 I clamped
the rib to the press table in two places before ever spinning the fly
cutter. I figured the two clamps plus the foot switch would lessen the
chances of doing open chest surgery on myself with a spinning wing rib.

The chuck key for my lathe has a spring on it. You have to press the
key into the chuck and, as soon as you stop pushing on the key, the key
pops out of the chuck.

The drill press we had at work had a safety interlock that really
worked. You had to put the chuck key arm in a switch before the drill
press could be turned on. The chuck key arm would activate a momentary
contact switch in the circuit for the drill press... no chuck key in the
switch, no drill press operation...

Sounds like a nice setup.

Do you also have to have a guard around the drilling area?

I see those in catalogs, but can not imagine how you could use one, and
still work in control, and be safe.

Yup, and the first thing the kid learns from the senior class is that a #29
drill shank will defeat that safety switch nicely.

True... you're only as safe as you want to be.

You just made me remember ties. My principal got enthused about teachers
looking unprofessional and required that all shop teachers wear one. Now one
feature of my personality is my undeniable propensity for "messin'" with
authority. I did comply with his dress requirement, but my tie was always a
"clip-on" and, in class, it was usually clipped to my shirt pocket. He never
questioned my fashion selection, but we'd have had a discussion on safety
issues if the point had been raised.(G)

Boy does that bring back a funny memory. Back in the early 70's when I
was in shop class down in Coral Gables High we had a great teacher who
was a bit of a "redneck". There was this kid named Tracy who had hair
down to the middle of his back, that kinda bothered poor ol Mr S but he
was a trooper and didn't give this guy too big of a hard time. Mr S
always kept the belt on the drill press set on the loose side so if
there was a hang up no one would get hurt too bad. Well, one day Tracy
was using the drill press and leaned over a bit too far and got his
hair tangled up in the chuck and sure enough it yanked him right into
the press. The teachers desk was about 50 feet away and after Mr S
realized there wasn't a huge threat to this kids life he SLOWLY got out
of his desk, walked over to the press and turned off the switch. By
this time the whole class was gathered around the scene and it was
clear Tracy was not hurt, but for sure pinned tightly to the chuck. By
about this time a grin came across Mr S's face and instead of just
grabbing the chuck and revolving it backwards to unwind his hair, he
slowly walked over to the tool board and got a big pair of scissors. Up
till then poor Tracy wasn't making any noises, that is till he saw the
scissors. Then the screaming started ..... Of course ya all know what
happened next G. The whole class laughed till we all ****ed in our
pants. Those were the good ol days................
