AZ tuned BSA Super Ten
Sent my BSA Super Ten to Allen Zasadny for some work….I can
not Emphasize how quiet this thing is now..Screw on LDC with
end cap to protect threads when not using LDC….Trigger is match grade
1 stage, and the fill adapter mod is a have to have….Cocking bolt
is cool too but everything else over shadows the knob….
Thanks AZ…..

Come on dudes. Give it a rest already. Those that don’t like it, don’t buy it… but you shouldn’t tell anyone else what to do if there’s no obvious issue.
This place is turning into a bitching and moaning pantywaste of a place to be. I like to keep up with every thread I can, to learn what I can, while I’m here… but having to wade through the shit is starting to suck.
hydroed as a unit and they passed for pressures generated by CO2 systems.
Mam, your glee is premature.
hardly a pass for the AZ mod.
Sigh. when are you guys gonna learn?? Life is not 2 separate bins, one labled “safe” and the other “unsafe.” You pay at the door and you takes your chances. Nuff already. Yes, I agree the thickness of the base does not allow for full thread engagement. But I haven’t taken apart one of these and wasn’t there something early on that said AZ does not thread these? He’s not an idiot. The best way to do it, if it had been me, would be to insert a base piece on the inside… the biggest piece that will fit through the neck hole… and have it mate via threads LONG enough to allow the full thread engagement heretofore addressed to the outside piece through a hole of minimal dimensions, to minimize compromise to the base strength.
Yes, I also agree any hole will weaken the base. That is a given. The question is not if that is safe or not. Holding a pressure vessel, any vessel, with 3000psi of air next to your face is not the best way to live to 100. The REAL question is, how much does it weaken the base? The only way to find that out is to test to destruction. Then run at half that pressure as your working pressure and you’ll be fine. Adam’s point is well taken, he’s coming from a slightly different angle. Fatigue stress and fracture propagation. That is always gonna be a problem and there is no easy answer other than to monitor it but not too many of us have access to an electron microscope. The tanks do not flex much, so that isn’t something that is on the forefront of my mind when I pressurize these things. The manufacturers have grouped this concern in by simply overdesigning and running more strength (and weight) than is necessary, to err on the side of safety and caution. So far it’s worked. How many tanks have failed due to fatigue stress cracks? I’ve never heard of a single one. For that matter, how many AZ tanks have failed? I’ve never heard of a single one. Would I use one? Probably not, I’m with Voltar, it gives me the chills. I have no doubt it is safe. But then, so are trucks and cars. But people die everyday when something or other goes wrong; it’s a matter of what you accept as a risk you are willing to take for the kicks you get outta doing it. Cost (i.e., risk of bodily harm) vs benefit (fun). This is not complicated.
What the hell kinda idiot says “Your banned” ??? If this was from a UK person, what excuse does he have not to know elementary grade syntax and grammar? Shouldn’t this be “You’re banned” as in YOU ARE banned??? Duh. Personally, I don’t mind being insulted, you’d have to wait in line for the privilege, but please, if YOU ARE going to insult me, do it in grammatically correct terms (otherwise known as the Queen’s English, for you wankers across the pond :))
aloha,

Don’t sweat it walt…AZ has made many of these and not a failure
yet…Doesn’t concern me….
NEXT SUBJECT…lol
Hell, I nearly got banned on AirgunAdvice for talking about LDC’s. Even though they have several people there making and selling them. They can talk about them all they want without a problem. The minute I brought up the subject, I was threatened. I was told that it was a forbidden topic on that forum. Yet 220Swift’s moderators are a sticky!
😕
This week I was again threatened for discussing Nitrogen fill tanks. These guys=mod’s are ignorant, fucking jerks. I say ignorant, because they openly prefer ignorance to knowlage. Much like many if not all of the UK Sites. As Mam-C learned the hard way. In fact, if they don’t know about it, It is forbidden to discuss period. Frigg’en pompass Idiots!

Whoa. Just walked in on this. Don’t want the shit all over me, that’s a lotta typing.

Well it seems that the quick fill mod has passed the hydro test….Might
not be AZ’s but, it works and it is safe…
Now all you nay sayers can publicly admit that you have no idea what
you are talking about and that you were wrong and AZ was right……..
Eye Candy CO2 Jet Car-Spirit of America

——————————————————————————–
I promised I’d post the pics when the Spirit of America Replica Jet Car was completed. This car is CO2 powered by two 20 oz tanks attached through the base of both tanks.
What makes this post on topic is there has been considerable controversy about whether this is an acceptable modification to drill and tap tanks with threads to accept Quick connect couplings. Because we like to make sure we are doing things safely we had the two Siamese 20 oz tanks hydroed as a unit and they passed for pressures generated by CO2 systems. The car was clocked at 68 MPH on a 32 foot tether making a 64 ft diameter circle in about 2 seconds. Total run time is just over 2 minutes. Larry Goddard is the builder with CO2 tanks provided by Mac1 and Hydroed by Ross Fire Extinguishers in Long Beach CA. The Jets Horn shape was generated from input from a good friend who worked on the Shuttle thruster development at Marquart.
Larry has some extraordinary toys including a paddle shift Ferrari 430 I’ve been invited to test drive when I get back from South Africa next month.
Larry does very clean work. He is definitely a toy lover and creator. To visit his home in Malibu is a delight and I do so as often as I’m invited.
He has some very nice airguns and is one of those guys that really enjoys his wealth.

I used to fill my UK “Condor” to 3500psi way back when and so did a lot of other people, with no apparent side-effects (still have all of my fingers and thumbs).
Oh no…Another renegade….I filled mine to 32 to 3,300 on a
regular basis….But then again I am known for being unsafe. I also fill
my SCBA to 4,600psi and I set my pressure relief valve at 4,800psi..I
don’t advise anyone to try this at home…Leave this to the
professional stunt guys like us…..
What? That’s unusual……Maybe they recognized your username
lol i tried but the bsa bastards wont let me in cock bags
This would be a relevant article

I am trying to find the article I read a couple years ago where they did microscope examination of scuba tank necks and found hairline cracks that occur over years. IIRC 8-10 years it can take for a hairline crack to cause failure.
I will keep looking and see if it is still on the internet.
Here are some facts showing sustained load cracking can occur but is very rare on a unaltered tank.

Tron, 3500 psi A/F tank? Does this mean that some are filling to 3500, or is this its max rating?

Although my response is somewhat redundent,
I Categorically concur…

Mam, your glee is premature.

Face it Walter,,If it held up to pressures of 50,000psi you would sitll say it
is not safe…
