The CZ Vz52 pistol perplexes me. I like the idea behind it: 7.62x25mm in a full-size service pistol, practically CCW-able, and not Soviet. Its lines are more art-deco 'ray-gun' than 'peasant woman' like the TT33 and its Browning (PBUH) predecessor.
The roller-lock is bad-ass.
But the drawbacks: eentsy sights, which can be corrected if you grit your teeth and say permanent good-bye to its collector milsurp value. European magazine release. A cast firing pin (aftermarket pin and retainer do improve the trigger pull).
The biggest negative: engineer Clark shows how the roller-lock pathways cut into the meat of the chamber, weakening it to the point that its roller lock gives it no power advantage over the Browning swinging-link unlock in the TT.
And yet . . . . if one could chamfer about the topmost millimeter from the rollers, and mill the topmost millimeter and a half from the roller cam, and machine a new barrel whose roller pathways did not pass the entire frigging way from one side of the barrel trunnion to the other, then you'd have a barrel without a dangerously thin chamber right under the barrel and directly above the trigger finger. And you'd have a pistol that could tolerate the chamber pressures of modern PPU 7.62x25 ammunition.
Then maybe it would be worth it to work a thumb-button magazine release into it. And something to warm the hearts of pistol historians, if US law would just get out of the way: a detachable shoulder stock.
No, I'm not giving a rat's ass about collector value on a milsurp pistol. I've WECSOGged nicer stuff than my 52. Besides, I have only 1 real safe-queen, my Dad's S&W M17, bought new in 1949, his wedding present to himself.
Update: We've been reading up on silver brazing, and how it's a fairly strong technique for joining metals but will not risk the temper in steel. So perhaps a slip of steel, say 2mm thick, shaped like the channel in the trunnion, could be quenched, then silver-brazed into place in the top of that channel. There would then be much more steel on that bottom wall of the chamber. Some metal would still have to be removed from the top of the roller cam, to clear the added metal.

NYT articles I'd like to see----Texas abortion clinic safety measures
WASHINGTON — The Supreme Court on Monday struck down parts of a
restrictive New York law that limits the number of permits to carry a
concealed weapon in the state to about 10 from what was once a high of
roughly 40.
...
The decision concerned New York's Sullivan Law, that imposes strict requirements on the issuance of permits that allow New Yorkers to carry concealed, own, or even handle a handgun.
One part of the law requires the Judge of the applicant's County Family Court to individually process the application for the permit, including personal references, interviews by a law enforcement officer, an inspection of the security measures at the home where the handgun will be stored, training requirements that must take place before the applicant can legally even handle any pistol, and a process that takes at least 6 months and approximately $250 in fees paid to the County, in addition to any expenses incurred for safe storage or training.
The law is also interpreted arbitrarily across the State, with some Judges and Sheriffs placing additional limitations on permit holders: prohibitions on concealed carry, criteria for personal references, or burdensome requirements for storage. These limitations are often applied retroactively, such as requiring a permit holder to install a fixed safe after a rash of nearby burglaries in the neighborhood.
“We conclude,” Justice Breyer wrote, “that ... none of these provisions offer law enforcement benefits sufficient to justify the burdens upon access that each imposes. Each places a substantial obstacle in the path of citizens seeking the most common and effective self-defense tool, each constitutes an undue burden on that access, and each violates the Federal Constitution. Collectively, these provisions actively discourage New Yorkers from even applying for permission to exercise what Heller and MacDonald clarified was a fundamental individual right guaranteed under the Constitution against infringement by Federal or State and local governments.”

HK bipod, finally
RobertRTG has been promising Pakistani-made HK91 bipods for some time. They finally arrived, and I bought one, because I am not going to spend as much on a gen-yoo-wine Kraut bipod as I did for the rest of the damned rifle.
Eagerly I lifted it to the forearm of my Springer/Greek HK91 to find that the bipod just would not stick on that little device there.
Back to the interwebs, to find that Springer had milled off half of that little device there, along with slapping on a perverted thumbhole stock. I bought that rifle new in 19-mumblety-mumble when certain cosmetic features were disfavored.
New forearms cost as much, almost, as the bipod. The value proposition of the affordable POF bipod was dissolving before my eyes.
Until I found a scrap fender washer of about the right dimensions, held it with a vise, and carved away all the metal that looked like it would not help hold that bipod on.
Then I wire-feed welded that chunk on the forearm, about where the necessary parts were ground off. The bipod now hangs there, and bears a little weight. I need some pointers on what sort of spring was riveted inside the handguard as a catch to let the bipod come back off. Any ideas or diagrams, dear readers?

Revolver conversions I'd like to see
I've acquired a Dan Wesson 15-2, plain-vanilla medium-frame revolver with room for a 6-round cylinder of .357 Magnum.
The revolver was designed to allow the owner to switch barrels, from 2" to 4" or 6 or 8 or whatever. The barrel itself is a tube threaded at both ends, and it rests in a shroud that can be vent-ribbed, full underlug, and so forth. One end of the barrel threads into the frame, the other in a nut that in turn threads into the end of the shroud. A special wrench gets at the nut, and a feeler gauge makes sure that you put the barrel back in with the right gap between breech end of the barrel, and the cylinder.
The cylinder wouldn't be so hard to take out of the frame either.
So why not a conversion kit, with 5-round .41 Mag cylinder, and replacement .41 barrel?

inspiration from today's address by MG X, The Adjutant General
Do not forget that the United States became united, in a fundamental way, through force of arms. The force was publicly demonstrated, but the arms were mostly private property.
The United States' union was later given structure and form, indeed purpose, through argument in philosophies that were informed by bitter European experience.
Takeaways: establish and defend a free space by force of arms, then govern it with logical application of fact.
In that order.

Hey, Cheaper than Dirt!
thanks for following.
how about some Fiocchi 7.62x39 in case lots?
Or . . . Berdan primers?

Mechanical aptitude
Mlle Sklodovska inherited one of my older Windows notebooks. It since had developed a nasty wheeze in the CPU cooling fan. She was going through a can of computer air per week trying to get some foreign object out of it.
Then one night, it stopped wheezing entirely. And started issuing dire warnings that its CPU/graphics/wifi adapter/younameit was overheating.
Newegg sold me a replacement blower that would arrive in days, not the weeks that eBay's Chinese sellers promised.
I talked Mlle through taking the old one out and putting the new one in. Which involved taking off the back, and the keyboard, and the mobo, to get the blower out. Many, many M1x4mm screws.
Thank God no soldering. The ribbon connectors---trackpad to mobo, keyboard to mobo, wifi to keyboard---are surprisingly robust.
Yes, this is a rewrite of the G4 repair saga.
Mlle also knows how to weld with wirefeed and regular stick. And her coaches at youth smallbore are coaching her to move on to highpower. She wants a shooting coat for Christmas.

It's not me you have to worry about, updated extensively
I have now packed heat lawfully in Colorado, Pennsylvania, Texas, Georgia, Wyoming, New Mexico, South Dakota, Kentucky, South Carolina, Arizona, Florida, Missouri, Nebraska, Georgia, Alabama, Virginia, Arkansas, and Utah. Wisconsin. Ohio. Iowa.
No lives were lost.
The way things are looking, I will pack heat lawfully in Nyawk and Cahlifawnia before I become a grandfather.
Note that there are slackers: I'm talking about you, Nevada. And West Virginia.

a difficult mother to tie
Prusik loops formed from .065" string trimmer line. For use as tandem belay on a hauling system based on .105" trimmer line. The 105 is powerful s#17, it broke a rope cleat today.
Tieing these little buggers was a trial. Next time, I soak the line in water a day or more before knotting.

Lautenberg violation for her too
So an ubicam in the elevator may have captured for Eternity that Ray Rice's at-the-time fiancee spit on Ray. Then he decked her with that left hook that even NPR's metrosexual sports commentators commentated. Sometime after that, they wed.
Question no one is asking: Will Mr Rice receive the coveted domestic violence misdemeanor conviction that Frank Lautenberg says disqualifies him permanently from firearm ownership?
Question that I am asking: does Lanay spitting on Ray constitute an act of domestic violence as well, rising to Lautenberg Amendment violation?
No, the question I'm really asking is: has a man been Lautenberged by a DV conviction, given for the act of spitting on his domestic partner? Yeah, that's it.

Visited a Jack in the box™ today and was invited to take their survey.

A cop can find who accessed her driver license record but . . .
A highway patrolman stops a speeding cop, the cop launches a prick war against her, and she files "a public records request with the Department of Highway Safety and Motor
Vehicles. It turned out she was right: over a three-month period, at
least 88 law enforcement officers from 25 different agencies accessed
Watts' driver's license information more than 200 times"

a chamber cast of Anduril
I took a chamber casting of the Remington 600 known as Anduril.
At the neck of the cartridge case, diameter is .348". At the freebore, it is .312". After the rifling has begun, it's .310"
that sounds a bit over. Any ideas, readers? Is this barrel d00med?
Update: using my l33t Bene Gesserit training, I managed to slip the caliper on the cast just forward of the freebore, between the lands, and it's really .308" in there, and I'm not scraping Cerrosafe off of the casting. Maybe not d00med. But the very short magazine box plus the approximately .225" of freebore really limits bullets that will touch the rifling. Would almost rather have the barrel pulled, lop off one or two threads of barrel shank, twist it back in and have a new chamber cut with less freebore.
Update 2: gotta keep in mind that Cerrosafe expands to .0025" oversize after it has done cooling, in another 7 days or so; this cast was taken Monday afternoon. That expansion is on the same scale as my measurements tell me the chamber is oversize in diameter.
And we found SAAMI specification drawings. The freebore is supposed to be only about .08" long. That may be the only problem with this chamber.
