Re: injuries from your machine?

In my younger days I was doing lathe work for some aircraft parts.
All nickel, about 12" dia rings. pure production, 5 parts an hour
for 2 years straight.

The rings were forged, we did a rough OD and face, a rough ID and
face, sent them out for weld inspection. did a finish OD and rough
bore, then they cut a 3 inch piece out and welded in a clamp. then we
did hte ID to cut that nickel weld, PIA !

By the time I got it back to a near finish bore and face it was split
so all the chips were about a foot long and nasty.

one day they built up in a rats nest under the guard and I saw this
one lone chip..... it was say'in Dave, I'll pull out reaaaaall
smooooth..... just grab me.....

Being a kid, I did, the whole rats nest caught on the chuck and
started polishing the insides of the chip guard. That little nickel
chip slid out of my fingers real nice. it's been 20 years and I
can't see the scar anymore.

then I was grinding without safety glasses. but I was wearing
gloves : ) The first doctor did't see anything, but my eye watered
all weekend. Then the second doctor looked, turned off the room
lights and looked again. then went to get another doctor. Seems the
nickel embedded in my eye was directly in the front so when they
looked the reflection looked like the water in my eye. from the side
they saw the sliver. Took 20 years before I was in front of a
grinder without safety glasses again. That time the doctor saw the
chip right away.

Thems, my experiances. I still have all my fingers and toes, see out
of both eyes, but unlike Jan, I only have a little of my origional
hair.
