Yeah, high pressure oxygen changes things a LOT. If you've ever seen an oxygen lance at work it's sorta scary. I don't think there's anything one of those won't cut through, and usually like the proverbial hot knife through butter. The concept is stone simple, just a hollow steel tube that's consumed by the high pressure O2 blasting through it, which when you think of it sounds a whole lot like sby rotorhead - Airgun Rendezvous Main Forum
Real pretty piece of work there, I like that all-white-metal look, and the bull barrel shroud looks appropriate to the piece. That's mahogany on the stock, isn't it? You know, that action looks like it could pretty easily be a long-barrel pistol with the right stock, sorta like the Victory series.by rotorhead - Gary's Galleries
Basic impact physics there, velocity trumps normal expectations every time. If you tried to hammer those slugs through your lead billet with a claw hammer, you'd just automatically assume it's impossible...and at hammer speeds...it's not. Add another thousand FPS, and those slugs would go right through 1/8" steel, add another thousand FPS on top of that, and they'd paperpunch 3/8" of regularby rotorhead - Airgun Rendezvous Main Forum
C'mon now Gary, don't go giving them any ideas. On a slightly more serious note, a couple of jobs ago I flew a civilian EMS helicopter that used a liquid oxygen dewar instead of high pressure bottled gas to supply medical O2. From a pilots perspective it was the cats meow, you only had to change it every three or four days instead of topping off the tanks every flight or two like you have to wby rotorhead - Airgun Rendezvous Main Forum
Yeah, I hijacked this thread and I'm not letting it go until you meet all my demands! Let's see, I want...uhm...let me get back to you on that one... Didn't I just read somewhere here that the function of the valve return spring is basically to keep the valve assembly from falling into the reservoir in the even that all the air pressure is discharged?

I think I like the personal narratives best, showing how and where and when people use their airguns and other tools. To be honest, I don't think there's been a post here that I DIDN'T like, but then I'm not that picky about free entertainment either. It beats the heck out of a bunch of teeny-boppers-at-heart discussing the intricacies of "Dancing with the Lost American Idol Survivors" or whateveby rotorhead - Airgun Rendezvous Main Forum
Pretty good basic description there, though of course it neglects the one small question about how you got that cork into the bottle to begin with. I've pushed a few in myself over the years; just never on purpose, and rarely in one piece. : ) It's got me to wondering though. PCP airguns have been built in enormous sizes in the past, in the form of "dynamite guns". Some of them had bore sizesby rotorhead - Airgun Rendezvous Main Forum
That looks like a huge batch of dowel pins for assembling swedish puzzle furniture. I guess if you keep adding rings, you'll eventually get to the point where the limiting factor is the slug protruding too far out of the muzzle when it's loaded.by rotorhead - Airgun Rendezvous Main Forum
I think that "clamshell gun" was pretty stinkin cool....FWIW. : )by rotorhead - Airgun Rendezvous Main Forum
I still think that you should make the hole down the middle of the barrel an option. If you charged twice as much for "full thickness" barrels with no bore, the safe-queen-only crowd would doubtless gladly pay the extra money to gain the cachet of having the "most exclusive model" of your work. You'd save a bunch of time too, since you could then also skip all those invisible and unnecessaryby rotorhead - Airgun Rendezvous Main Forum
Thanks for the link, those were some great photos! As an aside, I imagine that just a regular sheet of window glass would be an effective splatter shield unless you were shooting at steel targets, and perhaps even then some tempered sliding-glass-door type glass would probably suffice. It doesn't have to be on a moonless night either, just a dark area in the immediate vicinity of the target.by rotorhead - Airgun Rendezvous Main Forum
Hmmm....that wooden bolt looks like a very handy ammunition type. If you should somehow miss, just run out and grab it and you can use it to beat the target instead. ; )by rotorhead - Airgun Rendezvous Main Forum
It's a no-win battle with the "authentic antique" crowd. Their ideal collectible airgun is always one that's never been fired, is in perfect condition despite it's age, and most importantly...was made by someone who's long dead. That way there's NO chance that he'll ever make any more and upset their comfortable little apple cart as far as rarity goes. It doesn't matter if it never really worby rotorhead - Airgun Rendezvous Main Forum
Say....are those custom slugs available in mirror-finish chrome?by rotorhead - Airgun Rendezvous Main Forum
Personally, I could hardly run away far and fast enough from a project like that. It's got liability written ALL over it, in capital letters. Not just the legal liability (which is bad enough) but also the potential to damage your reputation and standing in the airgun community. Just a few reasons: Even if you did for some reason agree to restore it to original working condition, it wouldby rotorhead - Airgun Rendezvous Main Forum

There's some show on Dish Network that features a couple of guys playing around with a super-high-speed camera. The setup for each shot takes WAY, WAY longer than anything they'll ever film. The camera they use is all-digital and only records like ten or twenty seconds at something like 20-30 thousand frames a second. You'd think that synchronising things would be impossible, but the way theby rotorhead - Video Library
Yeah, duct gophers are hardy stock allright. Apparantly they're remarkedly resistant to whiplash as well. It's be interesting to see some side-by-side comparisons of duct-seal terminal effects by different Barnes rifles. Say, perhaps, like a Chief Justice. Gee...wonder who's got one of those?...

Good to see the Squire 45 out seeing the light of day again...wasn't that one of the first of the V-twin series? The Woodsman looks like a carbine next to it, or is it more like a trick of the camera angle?by rotorhead - Airgun Rendezvous Main Forum
I particularly like that folder with the damascus blade (or is it wootz?, what's the difference anyway?). I'm surprised that you can get such deep relief with the acid etching, it looks like engraving.by rotorhead - Airgun Rendezvous Main Forum

Isn't that stuff called "swarf" ? How the heck did they come up with that name, anyway? In addition to being a genuine PITA when it gets wrapped around chucks and centers, it's a reasonable substitute for razor wire.by rotorhead - I'm just sayin'
There are two kinds of shotgun shooters who can claim 1MOA accuracy with slugs. 1. Those who use premium quality rifled slug barrels with attached telescopic sights...and 2. Liars Just because it's mounted on a shotgun action doesn't mean it's a smootbore these days, at least not here in the U.S. Most pump action and several types of semi-autos have easily interchangable barrels.

How about a primer on scuba tanks for the absolute beginner? What kind, how big, how do you fill them up, how long do they last, what's the different kind of connections, air line setup, that kind of stuff. I've worked with compressed gasses in tanks for welding and aviation use, but I've never been a scuba diver or owned a tank myself.

Phenolic is still used for control cable pulleys on many small aircraft, and I've seen it used for control pushrod bushings and similar applications on light helicopters and other aircraft. When the aircraft manufacturers and the FAA find something that works, they stick with it...sometimes forever. ; ) You could say that they're resistant to change, but that would be a massive understatementby rotorhead - Airgun Rendezvous Main Forum
And speaking of smoothbores, how hard is it gonna be to talk you into some duct-seal carnage photos starring the .62 barrel while it's still set up, Jerry?
