"ztirffritz"If you're shooting through a cinder block then you're definitely pushing your luck with that gun. Accidents can happen, and they happen quickly.

This has got me thinking. I got two pcp airguns in my bedroom, filled to 200 and 300 bar behind a gun cabinet with a glass door facing my bed, probably not a good idea lol I will be looking to buy a good solid guns safe for my PCPs from now on.

As a fellow teenager who loves airgunning I completley understand your urge to build and tinker. I enjoy tuning my pcp's and seeing how they work. I do a lot of resaerch before I even consider to degas and tune them.
As you can see the airgun community is full of experts in many fields around engineering, but do you see any of these guys posting info on the pcp's they built? No. It is because nobody does it. Pcp's are not the place to try and devolop your BUILDING and MACHINING skills. Why do you think the pcp's that last a lifetime cost what they do? It is because people who have decades of experience spend years to design and THEN test their guns. 
I understand that you dont think the pressure of your pcp cilinder is dangerous, but ask yourself. If it can propel a led sinker through a sinder block, then it will easily propel a piece of your homemade pcp right through your arm

Adults in the airgun world have never been fond of children and now I understand why.

My son outshoots me off-hand with an open sights all the time and I am fond of him. What triggered "daddy mode" in most of us adults over here is not the fact OP has already done something really dangerous, but the fact he is clearly able to do that in the future if he continues the same path without investing into deeper research of the matter. And I don't think this forum is the right place for such researches.

Nope...not a social experiment of any kind. I guess this wasn't the best forum to ask questions about home made builds.

I guess the reason it doesn't seem like the plastic pipe exploding is that dangerous, is because I've had it explode before. And all it did was a loud bang and a little scrape like an airsoft pellet hit me and a nick in a cardboard box nearby. It just didn't have shrapnel speeding off in all direction at hundreds of fps. The farthest piece bigger than a half inch wide landed a mere 15 feet away.

There once was a guy who put a single round in a 6 shot revolver, spun the cylinder then pulled the trigger......it just clicked.....guess it's ok to try again?

Than go ahead and tell manufactures of products like ceiling fans that we should stop using their products, because maybe the blade MIGHT come off and hurt somebody. There's a difference between not happening at all (your example) and happening in a manner with a fairly predictable outcome.

For goodness sake if it weren't that way that demolition engineers would be guessing and hoping that the amount of dynamite they used to take down part of a mountain will yield the same explosion next time. The scientists who built the atomic bomb didn't know what the outcome would be when they detonated the trinity bomb, but they knew what the outcome would be when the blew up little boy.

Outcomes in the field are generally predictable. Damage sustained from the outcome............not so much. I'm not saying if it exploded again I would get just as lucky and not get hurt, but same thing, same pressure, same temp = same explosion.

Okay that didn't seem to make sense but whatever.

You really should stop countering peoples concerns with the danger aspect they see by citing useless examples of car crashes,falling off bikes or rolling out the wrong side of the bed.You seem to want your tinkering and experimenting validated by members who collectively have hundreds of years of experience in use,manufacture and modification of HPA equipment.
You have not recieved the praise or advice you were thinking you would find on this site and now continue your childish hissy fit.Give it up.I think the only way you will see the danger in your pursuit is visit to the ER.
All the best.
