LOL! Add that to the top ten list. I meant vice-versa.

You guys gotta be kidding? I've never been a close to a running prop
as I have a running lathe with hands and arms within inches of moving
things, hence the reason for never wearing long sleeve shirts when
working with machine tools. I've never been within two feet of a
running prop.

I used to get a lot of requests to "sharpen my bit" as I would
*finish* the edge of the bit on a buffing wheel. You could easily
shave the hair off your arm without soap or water and they'd really
hold that edge.

But as to safety, I've had a half inch drill bit pull a piece a 1/4
inch Aluminum out of the clamps and try to beat the column to death,
but I've never seen anything throw a piece like an innocent looking
surface grinder. I saw one smash a hole in concrete block wall.

Surface grinders are God's way of reminding you there's no such
thing as enough clamping force. My claim to fame is 10 feet with no
audience.

Now if you want to talk about unpowered tools that demand total
attention think of the english wheel. It's great for making blood squirt
out from under your nails and for causing one to cuss.

If it's not grade school kids I don't think most states have any
requirements. It doesn't even require a degree to teach at the
college level in many states. OTOH no many colleges will use a teacher
without a degree.

If it an "academic" subject (history, english, etc.) it requires a masters
degree for starters. For voc-ed, it requires either a masters, a bachelors
plus two years paid service in that vocation, or an associates plus five
years. There are a FEW of us old geezers around that got our commcoll
"credential" over 40 years ago, but even then it was for the subjects that
didn't have a degree program (like aviation ground school). If you wanted
an academic credential or a voc ed credential way back then, it was a degree
plus experience for openers.

We have a great electronics prof in our department who has one of the best
teaching styles I've ever seen, but his bachelors is in history, with 25
years as a non-degreed electronics engineer. I know he can program rings
around me, and I don't think the degree did anything for him except teach
him how to teach.

This is for community college in California only. I don't speak for the
university system or any other state, but I know of no university teacher
without at least a bachelors and working on a masters.


C is average which is supposed to indicate adequate knowledge. B is
above average.

That used to be true. Current thinking is that a C is "just barely
passing", a D is unsatisfactory work, and F is failure. I don't want "just
barely passing" flailing around on my lathe.


I think that is probably one of the few things that are cheaper in
Ca:-))

College, nasty women, avocados, and wine. All else is higher. {;-)

You got that right about the surface grinder! I worked in the
Wichita State University machine shop during engineering school,
and I once saw the surface grinder throw a BIG hunk of steel
across the room. Along with the shrapnel from the grinding
wheel, it was pretty impressive. The thing that made it even
more memorable was that the grinder was being operated by the shop
foreman at the time g

In general the mill is just a big drill press and about as safe unless
using a fly cutter.

We do have face shields, but they need their own leather gloves. I
almost always wear tight fitting leather gloves and short sleeve
shirts when working with machine tools.

Roger,

I'm not sure I can agree with you about wearing gloves. If you get your
gloved fingers too close to the spinning bit you risk the bit "grabbing"
your glove and pulling your hand into it. On the other hand, if you're
not wearing a glove you might lose a bit of skin or get cut but it's
unlikely you'd be "grabbed" by the bit.

I agree completely about wearing short sleeve shirts. However, that
"rule" goes 100% against the rule to always wear long sleeved cotton
shirts when working around electricity. Since our shop was part of the
Technical Metering Department we would often move directly from a 480
test setup to the drill press...

Different hazards.... different rules...

At my school wood shop we had a large planer with a huge heavy duty vacuum
chip catcher located about 10 feet from a large table saw. The chip catcher
had a fairly thick metal cabinet and there were numerous deep small diameter
dents in the cabinet. These
dents were the result of improper choices made by persons using the saw.
Kick backs
from cutting small slices off the wrong side of the material resulted in
unsupported spearlike scrap pieces jamming between blade and fence and then
being propelled
off the back of the saw at high velocities. I'd carefully demonstrate this
as part of my safety classes at the beginning of each semester and point out
the dented equipment. While I taught there, I never had a student make that
particular error. Any additional dents added during my time in that shop
were carefully staged Demos.

C means that the student has average grasp of the material. That means they
will have an average number of accidents.

I could just be a hard ass, but that isn't good enough for me. My students
must get a high A on all safety related tests. Then, they must be able to
give me the correct answer to any of the missed questions on the first try,
or they have to take the whole test over again, and again, until they can do
so.

It must work. My students have very few serious accidents in the shop, or
on the job site.

The local EAA chapter has a lathe, drillpress, milling machine, etc
set up in the back of the chapter house. As far as I can tell, the
lathe hasn't been used in a while. When I asked, someone rightly
replied they were concerned someone might hurt themselves using the
lathe. Having had some training with a lathe, I recognize that danger,
but there should be a way for the Chapter to feel comfortable
allowing use of the lathe. A training program would be ideal

Has anyone else been faced with this situation and how did it get
solved? - MIke

Those machine are killers. I suggest they pack them up and ship them to:

Seriously, if you guys want to stop at my shop on the way to OSH or any time
I'll be glad to give a class on machining. You brinng the beveridges.

Dan, You and Tom are obviously concerned for the good of others, and
I commend you. However, I'd be willing to come pick them up tomorrow
just to make sure that no one gets hurt in the meantime. Those machines
are just like a loaded gun laying around waiting for one of the kids to
pick it up. Think of the liability ;-)
