Doc,
Mag makes some quite small flashlights now. I believe they have one
that is keychain sized. That would be an aweful small gun barrel, plus
if it's on your key chain, it goes in the basket when you go through the
metal detector :-)
I really should pick one of those up myself. Hmm, I DO need to go to
Lowes today, any way :-)

If you have store or like that carries Garrity brand, pick up two
cell AA flashlight. Plastic body, but ends are rubberized, has
rubber tog attached. Reflector is faceted and projects bright spot
far away. So far I'm still on orignal bulb and replaceable with
any standard bulbs anywhere. Switch is push on-push off button type
not those crappy slide type. The Maglite bi-pin bulbs are big
pain, they burn out quickly, hard to find and costly. Yes I had all
types of flashlights including Maglite.
Yes, I did know there's second bi-pin bulb held in place of red
holder in Maglite's end cap hidden under that spring.

What the problem is that 2xAA version of Maglite bulbs blew easily
and often. I would find myself swapping bulbs 2 times every set of
batteries. This is smyptoms of overdriven bulb even Maglite says
this is correct bulbs package.

I have a single AAA on my keychain too. It is my second one,
something got messed up with the rear end connections and then with
the switch, so after many years (nearly all the black paint gone) I
got another. Not terribly bright but very handy. Have used it to
peer under raised computer room floors, but mostly use it for some
little close purpose every few days.
For our wedding we had double AAAs embossed as favors for our guests
(small wedding). Nice little light.
But for a *real* flashlight that is roughly the size of a double AA
Maglite, I have a Sure-Fire 9P. It has a prefocused bulb & reflector
and is powered by 3 #123 lithium cells. This puppy looks bright in
daylight. I think it was the recent Godzilla movie that used a bigger
model as "practicals" that were carried by some of the actors. A few
episodes of the X-Files have used the same model as I have. Unlike
the double AA and double AAA Maglites, the Sure-Fire will not come on
by mistake in a bag or pocket.
Being one who figures that some toys would only make me less secure in
my person, I don't have the handgun mount (flash this in someone's
face at night and you will only know if s/he is reaching for
something, the light will stun your subject), but I do have the NiCd
conversion: a battery pack, a short extension barrel so it will fit,
different voltage light, and charger.
Not chaep. Not easy to find. Very nice light.

That's what I carry. It's about 3" long, maybe 3/8" or 7/16" in
diameter. They won't let me on the plane with it. Had my friend who
works for United not been willing to come get it at the security gate
and store it for me, they'd have confiscated it. Now I put it, and my
little 2" Very Sharp Knife in my checked luggage.
The truth is, I have absolutely no beef with that. I fly a lot. I
now get to the airport at least 2 hours before my flight. I often have
to spend an extra night out of town because of the added check-in time.
I don't schedule connecting flights less than 1 hour from scheduled
arrival to scheduled departure.
And flying is a _much_ more pleasant experience. For the first time
in my experience, the flying public don't treat airport and airline
personnel like personal slaves. My aforementioned buddy has some unreal
statistics. Lost baggage is down over 60%. Complaints and claims
blaming the airlines for missed flights or connections are down nearly
75%. The airlines are more on-time, due to a lighter schedule.

Well, I guess "confiscated" was the wrong term. My checked baggage
was checked, my ride dropped me and left, and my only option was to
leave it there or leave with it. So if Jim hadn't been on shift, I'd
have probably lost my light.

Saw a lasy in Denver in November show up at the security check-in 20
minutes before her flight boarded. She naturally got tagged for a
thorough search, and started screaming at security about missing her
flight and her rights. It wasn't security who very quickly shut her up,
it was the looks she was getting from the other travelers. Quite
gratifying.

Well, they don't like it if you look too close, and the corporal at

I doubt they were AR-15s. The only ones that the US military ever bought were for the
USAF in the early sixtys and before they were accepted and standardized as the M-16. Even
those AR-15s were full auto. But most AR-15s are semi-auto only and are sold to the
civilian market. The AR-15 and M-16 are exactly the same size. The only difference would
be if you got a target version, carbine or something else that is non-standard. But even
those use the same receiver, magazine, etc. One thing that might be throwing you off is
the fact that the current AR-15s and M16s use a longer heavier barrel and a bigger ROUND
hand guard than the Vietnam era M-16s that many people are used to seeing.
Incidently, that sale to the USAF is what got the US government (civilian, not
military) looking at the question of what was the best arm for the military and that
ultimately lead to the abandonment of the M-14 and the adoption of the M-16. (just in time

Only special forces get those. All regular forces of the USA, USAF, CG, Navy, etc and

I think what they should do is hand out multi-tools to everyone
on the flight. If there are more passengers than hijackers,
I think they can overpower them.

You don't have to buy a tap and die set unless you're really into tools for
their own sake. I've had a tap and die set, and, until a year or so ago, a
completely equipped machine shop, with equipment ranging from punch presses to
various lathes and milling machines. While I'm not an expert machinist, I
have managed, over the years, to learn how to make relatively small and quite
interchangeable parts, and very precisely fitting ones at that, without
hurting mysielf, and without creating too much scrap. I've even managed to
learn to limit the number of taps I break when I'm required to tap a 2"-deep
hole.
I personally have used a die for threading rod only once in the ~30 years over
which I've owned one. Normally, when I needed a tap, I simply bought one, for
about half a dollar. Now, I'm not quite ready to give up the tap wrenches I
own, but of the dies I've had, only one has ever been used, and that one only
once.
For what I've seen on this thread, a roll-tap and a tap wrench, the latter
being best bought at a used tool sale or pawn shop, would be quite adequate.
The lubricant of choice for sheet metal, tapped by the usual home user, would
be hand lotion. Special lubricants aren't necessary.

Large taps cost more because there's more steel in
them. A small tap is the
size of a pencil lead, while a large tap is the size of a drinking glass.
Common sizes are cheap, but the smaller ones are easy to break. Most of the
taps I've seen broken, or broken myself, have been broken in a hand operation
rather than in a machine. Once set up in a machine, they generally go dull
before they break. A few out of every box do break, however.
everytime! I have some taps that date back to the early 1900s and are still in
good condition. Odd size taps costs a small fortune! I've got some that cost
well over $200 each (not that I paid that much for them). I probably have over
$5000 worth of taps alone and they all fit into cabinet that measures 8 x 12 x
15".
That's not necessarily the case, if you tap
10K holes per day. You buy lots
of taps because every 30th-100th time you have to replace the by now dull tap
with a sharp one. You then decide whether you want to buy new ones or have
them sharpened. New ones are generally cheaper, so you sell the ones you
don't break to someone who sharpens them and resells them You can buy
resharpened taps, too.

That's probably why he's throwing them away and buying new ones
