a little closer to reality, perhaps?

Usually, my posts titled "Idea number xxx" are flights of fancy, if-wishes-were-horses proposals. If I could finance them, I suppose they would be feasible, technologically, but they'd need someone with completely different skillsets to find the willing market and make the sale.

It pleases me that STOL airships are far closer to reality. Of course Dynalifter does not list medium-haul domestic passenger airlift as a potential market, as I had wished. By the time such craft and services are available, if ever, I will have little need to go to the East Coast anymore.



But that's not the point. Maybe I'd buy stock in it.

at VC

An interesting post by Ilya Somin, about the divide among libertarians on the US occupation of Iraq. Milton and Rose Friedman are quoted.

Please don't challenge me on the choice of "occupation" for what the US is doing in Iraq. By plain-English definition, that's what we are doing, and I use it with no intent to challenge the intent or wisdom of it.

I left a comment there, after wading through mounds of libertarian blather about abstraction versus the concrete, moralism versus consequentialism or utilitiarianism, and walls of flame. Plus some gems. It deserves the rare, vaunted Second Reading.

It isn't enough to simply oppose or support this conflict. Slogans such as "oppose the war but support the troops" and "regardless of how we got involved, we still have to win" don't even scratch the surface. In a way that transcends foreign policy or the face Uncle Sugar puts on diplomacy, regardless of whether American boots marked Saudi soil, this war was coming to us one way or another. Why we fight it predicates how we fight it, and how we fight it determines whether we will win it. If we are not fighting for the right reasons, we will lose.

Why the DoD will not switch from SSN to random service numbers

Bruce Schneier:
We generally think of computer security as a problem of technology, but often systems fail because of misplaced economic incentives: the people who could protect a system are not the ones who suffer the costs of failure.


DoD will not suffer if my SSN is compromised and my identity is stolen. I do.

Unless the incentive can be turned on them, they have no reason to change.

Mideast, short and sweet

James Rummel prompts me to remark that the face-packing in the Levant is a bit overdue.

One newsreader earlier this week referred to Israel's defending herself against Qassam rockets and UCAVs as "perpetuating the cycle of violence."

Madam, this is no cycle. The violence over the last few weeks all seems unilateral to me. We can hope that the Lebanese government, if there is one (or if a sensible one is in waiting) will see this as an opportunity to eject unwanted puppeteers and determine their own future, and set their own relations with neighbors.

If the US intervenes as a so-called nation-builder, let them learn from recent experiences in Iraq and Afghanistan. Do not value democracy so highly that this new democracy you build can merely vote down the rule of law, the right to own oneself, and the right to be equal before the law regardless of one's practice of this or that religion. Talk to the speechwriters and find some word other than democracy to bring tears welling in Americans' eyes.

And speaking of James, I'll be taking dinner with him this evening.

To the finish line!!

I know, I know, I haven't posted in a bit. But see, I'm better at being a Gear Guy than I am at waxing politic. So here's a gear post for you.

Background first. I snagged twenty-two (that's 22...) HK-91 steel mags off of GunBroker a couple months back for cheap. They were advertised as having "minor surface rust". I figured, what the heck, a little elbow grease and they'll be as good as new. I posted the winning bid at $42 and they appeared on my doorstep about a week later. Well, lemme' tell ya', minor surface rust, my ass!! They were nasty!! Now I had a decision to make: toss them or continue throwing money at the problem. Being that I am The Cabinet Man, throwing good money after bad has never been reason to stop while I'm ahead. Now, I've never done anything like this before -- never even held an airbush -- so this was uncharted territory for TCM.

So, I had the local headstone/memorial shop sandblast the buggers inside and out for $50. Then I ordered two kinds of finish: Lauer Weaponry's DuraCoat "Black Oxide" and Brownells' Teflon/Moly Oven Cure "Dark Park Gray". Not knowing how much would be required, I ordered a pint (16 ozs) of each. I also ordered an airbrush kit from Lauer that included a 1/4"-to-1/8" adapter so that I could use my air compressor for this task.

When back from the sand blaster, the mags had a nice gritty surface. They were so clean, they were silver colored!! I degreased them with acetone and then used a new toothbrush and compressed air to get rid of the cotton fibers left behind from the cleaning rags. I connected all of the airbrush goodies and was ready to go. (NB: the "instructions" -- and I use that term loosely -- for the airbrush were non-existant. I had to figger' the whole thing out myself. Not impossible mind you, but it didn't leave me with warm-fuzzies. Remember: newbie here...) I cranked down the line pressure off the tank to 45 PSI, pulled on some latex gloves, and was ready to go.

Brownells first.

The directions on the can specify that the metal to be sprayed should be warmed to ~100°F. To do that, I just laid them on a piece of plastic sheeting in the driveway for a few minutes. It worked great. I sprayed on two coats about 1/2-hour apart. The finish dries very quickly to the touch. In the case of bare steel, it was a matter of seconds (literally!!) until the freshly sprayed mag could be handled. After letting the second coat dry another 1/2-hour, I put them in the oven at 300°F for -- you guessed it!! -- a 1/2-hour. And that was that.

Now here are the negative details. First, there is no indication on the Brownells can of what to use for cleanup. Nothing I tried worked. Acetone, kerosene, mineral spirits did nothing. I finally disassembled the airbrush and scraped it clean with rags and pipe cleaners. I got it cleared-out enough to use later with the DuraCoat. Second, since the Teflon/Moly stuff dries so quickly it was tough to keep the airbrush clean and running. I was constantly fussing with the flow nozzle just to keep it clear. Third, the baking process is very stinky. Make sure you have a way to properly ventilate. I opened all the windows and ran the attic fan the second I smelled chemicals. There's a slight lingering odor but not much.

The good. The Teflon/Moly goes on very smooth and even. It's easy product to work with, needing no hardener or reducer. The color is a perfect match to the gray parkerizing I've seen on mil guns. As far as I'm concerned, the Brownells Teflon/Moly is quite idiot proof. (Thank God...) I used just over 1/2 the can of finish (~8 oz) for eleven (11) magazines inside and out.

DuraCoat next.

DuraCoat has no special requirements for preheating the item to be sprayed. Unlike the Brownells stuff, DuraCoat comes with a reasonably clear set of instructions. (It wasn't until I read them that I discovered the need for their reducer for clean-up. I went back to the Lauer site and it does state this, but it's not obvious...) The DuraCoat finish comes with a small bottle of hardener that needs to be mixed at a 1:12 ratio (hardener:finish). Throughout the DuraCoat phase, I mixed the hardener:finish in the color bottle a few tablespoons at a time. Not so good for consistency but it was all I had. Using the DuraCoat proved to be quite a challenge.

First, the DuraCoat is much more like a paint than the Teflon/Moly. It sprays on OK but remains wet for almost a 1/2-hour. This slow drying process made it difficult to spray the entire mag -- inside and out -- in one pass. It's also a very "sticky" finish. After the first couple of magazines, my gloves would stick to everything: the mags, the sprayer, the drop sheets. By the time I finished the eleventh mag, the airbrush was a sticky, globbing mess and my gloves were useless. It was very frustrating.

I also had trouble with paint "blobs" from the airbrush. I don't know much about them so I'm not sure if this was a "feature" of the DuraCoat or of the airbrush. (You can see one of the blobs in the center of the mag pictured below. This is actually one of the minor blobs. There are worse...)

One thing the DuraCoat does have going for it is that "a little goes a long way". I used very little product, less than half what I did for the Teflon/Moly. I also got the sense that a second coat wasn't needed. I still applied two coats to the feed lips and the areas that will contact the rifle (basically the upper third of the mag). Perhaps someone more skilled in such things would have put on two thin coats but my setup wasn't working well enough for me to do that. In hindsight, perhaps a bit of reducer in the mix might have helped with the blobs. I dunno'...

So here is the final result, DuraCoat on the left, Teflon/Moly on the right:



In my opinion -- at least for this application -- I would definitely choose Brownells Teflon/Moly over the DuraCoat. Sure, I had to hassle over the airbrush clogging while using the Teflon/Moly but it produced a much smoother, more even finish. And it was just plain easier to work with. Only time will tell which will wear better. In hindsight (#2), I should have experimented with just a couple of mags for each finish. That way, I'd have 20 mags in Teflon/Moly rather than just 11. Maybe DuraCoat works for other folks (those with better equipment?? with more patience?? with actual training??) but it didn't work so well for me. YMMV...

Thumbs up, Brownells Teflon/Moly Oven Cure!!

Since it's Disney Channel Games week, . . .



Screw the games with guys racing each other inside inflated balls. The sidekicks on Disney's shows are, shall we say, more interesting. Since as a father I have to watch this stuff anyway---otherwise the offspring units will be Very Pissed and not eat their broccoli---throw us dads a bone.



Mix it up with the Spike crowd and expand your viewership, Mickey. Work the studio system to the full extent and make sure these properties actors have a future once they are old enough to check themselves into rehab. Not every one of them will be a Kurt Russell.

Alyson Michalka represents Phil of the Future.

Anneliese Van der pol shouts it out for That's So Raven.

Wrestling in vanilla pudding.

Old gray mare ain't what she used to be

My sister-in-law's Volvo sedan has rolled its odometer twice. Not sure what's wrong with it now, but many of the motorized electrics don't work, such as a window or two, and other maintenance items are adding up to the conclusion that it needs to be replaced.

SIL wants a hybrid. I stress that hybrids' price premiums will not break even on the saved fuel unless gasoline prices climb above maybe $5 a gallon and stay there, or much of that price premium disappears in 6 months. She's also 6'3" or so, and of, er, ample proportions. The little streamlined monocoques of the Prius or the hybrid Honda will probably not fit her.

She has a loooong commute from Herndon VA to Frederick MD every damn day. Any place she'll move to early in the life of this car will create a commute of comparable distance.

If she wants the fuel economy and the long engine life, and the option to use a biologically derived fuel, I'm thinking diesel, as I am thinking of it for myself. Will a woman of SIL's proportions fit into a Jetta TDI? (yeah, they take a price premium too---ever price a pre-owned TDI? Still, it's manageable.)

Are any other carmakers offering or planning performance-diesels for passenger cars?

Speedfreaks

We are with in-laws in Western NY, and took in Six Flags at Darien Lake yesterday.

Firstborn enjoys the fast coasters, though she becomes a sobbing mess while waiting to get into the car. "Is she OK?" ask concerned riders just before we climb in. "Is she gonna be alright?" Makes me feel like a child abuser. But the sobbing is gone after the first steep drop.

Predator was very good, but Ride of Steel is the shiznit. After that, two turns on the Viper and she was done with rollercoasters for the day.

Carhenge



Now that we live within a couple hours' drive of this place, all I needed was an afternoon free as the excuse to get there.

More on this later when I craft a satellite overhead comparison of this to the original. How faithful were the builders? Have differences in its location on the Earth been compensated for?
