So I've had this kid working for me for a while now. He does not have
the same work ethic I had at his age. But he is getting better. He is
absorbing information. Last week I had him single pointing threads for
the first time. First item was a 1 1/2 aluminum pipe nipple. I needed
the aluminum pipe cap to thread on loosely so that the end of the
nipple would bottom out against a rubber gasket. After showing him how
to pick up the threads and doing one my self his job was to do the
same thing. First on a solid blank without any threads to get a feel
and then the real thing. He did a good job. This was easy though
because the nipple only had to be a loose fit in the cap. After doing
the first one I discovered that I had ordered the wrong threaded
fitting for another part of the same project. The fitting is made of
brass and is for a gas connection involving a metal to metal seal. The
threads for this part are 5/8-18 left hand on one end and 1/4 female
tapered pipe on the other end. The metal to metal seal part on the
fitting is part of a .250 radius sphere. These are common fittings.
So, I made a sketch and showed him how to cut left hand threads. Most
important was that since the threading tool starts in the thread
relief if the half nuts are not engaged at the right spot he wouldn't
have time to disengage them before the part is scrapped. He practiced
cutting air until he was ready to do the real thing. He made a good
part the first time! He used a thread mike and I had him make a class
2 thread. The PD was in tolerance when he was finished. After the part
was done I smeared a little prussian blue on the contact surface and
threaded the fitting into the mating part. After unscrewing the
fittings he was able to see the line contact where the bluing was
squeezed away by the two mating surfaces coming into contact. It sure
made the guy feel good to make a part completely on his own that
matched the print and looked better than a store bought part. Since
this fitting is now installed in the water cooler line for the TIG
machine every time he TIG welds he'll know it's his part that finished
the job and that keeps the torch cool. He was so pleased with himself
I think he'll tell all his friends about it. Made me plenty happy to
see him do a good job too.

It sure is nice to watch the old light bulb snap on. Be sure to reserve
some unpleasant tasks for him however when he gets a little cocky.

At the lock shop when I would catch the apprentice goofing off or if they
made the same bonehead error for the umpteenth time I would send them out to
clean my truck, or send them to clean the john. The latter was when they
only mildly annoyed me.

they come up with this striped stuff.

Around here, both would be spotless from the constant attention.

Congrats, Eric

then there's the flip side...

I hired a kid from our shop's neighborhood. High school senior, attending
the welding program in vocational technical school. He achieved a
certification for arc welding. I'd love to attend this program.

He has since been graduated, and moved on to another job (whew). He came to
dad and asked if he brought a sample of this material he and his buddy
found, if dad could identify it. It seems the certified welder wans't sure
if the metal bars were steel, or not. This, after working in a machine shop
for a year...

Dad asked him if the bars were heavy.
" Oh yeah, there's lots of them."
Then dad asked him if a magnet would stick to them.
"Uh, we don't have any magnets at home."
Dad then asked if he had any refrigerator magnets.
"Oh, yeah, well, we didn't try that."

The certified welder asked me to buy 50 lengths of metal bars, like, you
know, about1/4", or as small as you can buy them.
"Jesse, I can buy steel wire as small as hair."
"Oh, not that that small, but like, whatever."
Fortunately, the "metal rods" are for sculpture, not bridges.

I'm sure that soon he'll be welding carnival rides somebody's kids will be
on.
I don't have kids.

Well, after the trainees success with the gas fitting I thought that
maybe he should try something else. I needed an adapter from a faucet
spout to a sprayer head. The hardware store had plenty of adapters but
none with the correct thread. This is a part he can make that must
work but has a little leeway. Success again! Without me hovering over
his shoulder. Then yesterday I needed an adapter for 1/2 of an oldham
coupling. One end has a .5000 hole and the other a slot that fits the
middle part of the oldham coupler. So far he has bored the part
correctly cut the slot so that the coupler part slides but there is no
side play. He still has to cut two more slots and tap a hole but I
think he's going to make this part good right from the start.

Eric,
The kid is lucky to have someone who cares about how he does his work,
and can show him how to do it correctly. You are as much of a gem as
he is.
