Q:

A word of caution

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

Now that I think about it if the wall was too thin it would just tear until the extra pressure was released…

This thing tore right around the outside diameter at the full thickness of the metal… 😯

If this was a common shot then many more shrouds like this would break or at least split along the fluting…

The huge bang is not something normal for these rifles, so the hole had to have been plugged or there was a combustion of some sort that ignited left over oil or something in the barrel or shroud.

Sure there is lots of air moving through the barrel but if it were so much that it could continue to rip the shroud past the original tear and into virgin metal we are definitely talking a little something extra to produce that type of energy…

It’s just too much damage for one normal shot, even from a Condor…

YW

Thanx crackin, you the man !!!

mmmmmmmm mmmmm, Sawtime agrees, that shroud was seriously shredded, at least no one got hurt physically,wasn’t exactly good advertising campaign either.
Accidents happen and this thing was an accident we will probably never know :10 :18

The one flute was milled too thin, I dont have the measurement but feel there is a little more to the story to have such a catastrophic result.

Tony, any thoughts on the failure?

Possible to get the dimensions from the split?

Interesting looking guitar you got there, son. You been tryin that new fangled rock n roll?

There is no way that was caused by “dieseling.” The air entering the shroud is expanding rapidly not compressing.

It is possible to get a small diesel effect from a pcp but it takes a lot of pressure and a slow to start (moving) pellet. I once cleaned my barrel with a very wet with oil swab and than shot at maximum power with a very long and heavy slug. I got a little smoke out of the breech when I opened it to reload. Meanwhile, the shroud was getting wet from condensation as the air leaving the barrel was cooling from expansion. It is not unusual at all for condensation to form on the shroud when I’m putting a lot of rounds through the gun. It just gets cold from all the cold air coming from the barrel.

quote Anthony266:

That is my shroud. It has been returned to me and I am still trying to figure out what happened.

This is an isolated incident and I will have to investigate futher.

Tony

There are several views that something strange has happened…. I agree and perhaps has been a dieseling detonation…

If the owner has used any mineral oil or petroleum product to clean or lubricate the barrel and pellets … then an explosion can occur through self-combustion of excess oil to be submitted to the relatively high pressure inside and outside the barrel.

This would be sufficient to make the effect we have seen here with this shroud.

The manufacturer would not be guilty then… .

I would love to know how thick the wall is it looked around 0.075 to me

Any updates Tony?

how about thickness measurements?

Walter…
