A word of caution
Remember, these are high pressure guns! More on this later, I have to get back to work right now.

I used 1.250″ OD 0.065 wall thickness 6061 T6 aluminum and by looking at Shooterjoe’s pic, the wall thickness on my shrould seems to be at least twice the thickness of his.
I know that the Condor develops a lot of power but, I can’t see the 6061 T6 Aluminum being too weak to use for the shroud, unless the barrel becomes ubstructed. With an obstructed barrel, any gun can split the barrel or shroud.
So, opinion time, is 0.065 wall thickness 6061 T6 aluminum too thin for a shroud? What thickness does everyone use?
Your ally tube is good to 1000psi and so is plenty safe for a shroud as the burst pressure is over 3,000psi
Reducing wall thickness reduces pressure handling.
I use sch 40 mainly because it easy to acquire 🙂

All of you have the same information that Tony does. He was thousands of miles away when this happened, Im the one who pulled the trigger. I realize you all don’t know me, and Im not an acomplished machinist as many of you are,but I do know what Im talking about.
I do think it split on a flute. The end cap and some baffles are still MIA, mabe on my neighbors roof.
This is no witch hunt! and do not misinterpret the quest for truth and honesty as one.
The tube is too thin, it is clear it split on a flute
The cause is too much pressure for the wall thickness in the design.
Because this is isolated as in the first published it clearly establishs teh weakness in the shroud. This may occur again and so in the name of safety and good design practice it is wise to get to the bottom of it. Then teh ‘methods to prevent reoccurence’ can be taken.
Venting the frame and tube is not the answer to prevent this as the pressure wall occurs too quickly inside that chamber.
I for one am thrilled to see open and honest discussion and do not see this as any witch hunt.
Thank you Tony for stepping up.

Sorry Tony, I didn’t realize this would become a witch hunt. 😕

I am ordering my .22 Condor next week. Have allready made the shrould for it. After seeing Shooterjoe’s shroud and reading Voltar’s comment that he uses 1″ schedule 40 aluminum pipe, I am wondering if my shrouds wall thickness is too thin.

No shit! My DRO sometimes gets a mind of its own. Sometimes while I am machining everything is going along just fine then I look up and the readout is not what it should be. If I did not pay attention it can go down hill very fast. What I learned is in some scales moisture can get in there and make them go whacky. So I hit it with a hairdryer and they behave again or at least until the humidity is up 🙄
It really would sucks if you moved your DRO .005 and it really did .015. Been there and done that.
You know how while machining sometimes stuff will move a hair and sometimes a hair is to much.
I shattered a 2 1/2″ diameter drill bit once…it was about 18 inches long when i started and ended up about 4 inches long…the table moved about .005 and thats all it took 😆
Thanks Tony,
My shroud from you is no problem for sure. I am willing to bet the fluting pushed the edge to thin.

Okay the mob can go home now….LOL
It’s the closest ive got’n to seeing the insides of one of your shrouds. 😆
I may have to buy one just to get a better look.
Ive had silencers n shrouds shoot off over into my ( very understanding ) neighbours yards in the past.
How we laughed. 😯
Thanks Tony. Send it to CSI Miami. They can figure anything out in under an hour and thats with commercials.
This is an isolated incident and I will have to investigate futher.
Tony
Thank you for claiming it, I for one feel better that it’s one of yours, that means it’s only one out of possibly a thousand built so definitely an isolated incident, and it will be addressed.

Tony
oh, good, thankyou Tony
The material is too thin and I’m betting he is on the verge of tank dump.
I would rec’d you recall all shrouds made this thin with flutes on Condor class guns at a minimum.
glad no one got hurt
Walter…..
That is my shroud. It has been returned to me and I am still trying to figure out what happened.

Tony
Tho i have had my share of fuck ups.
I ( and i mean we ) are only human.
Later all.
I completely agree with you 100% my only suggestion to those out there that want to make there own moderator or are currently producing them for sale it is always a good idea to use a thicker wall on the tubing to protect the shooter from possible injury or possible death.
I believe the individual that did produce this moderator should come forward not to be lynched but to re insure the people that have bought them that they are safe and have nothing to worry a bought or to offer a recall on that current run of possible bad tubing that is just my opinion.
Not guilty.
I am still testing mine, before I start to sell them.
semper fi.

Why do you think Im on the verge of a tank dump? What would cause this?
