I have a huge CRT that i need to stabalize so it can be removed and trashed, ive left them in the garrage under vacuum and had one implode into 1000's of glass shards, is there a way to vent air in without breaking it all to pecies?

socket.
Same advice but I first make a hole in the removed outer casing and pass a small diameter steel punch , through it, and onto the that spot, a pip on the end of the neck of the CRT. The covering just in case what should be just a snmall hole should become a big hole - I've never experienced it but is a possibility.

and place the screen surface down on cardboard , not concrete, before knocking the hole in
Ummm... put the CRT inside a few layers of plastic trash bag before releasing the vacuum perhaps? If it breaks, at least it doesn't make a huge mess.

I used to take the old CRT's out to the desert for target practice. (This was in the 1960's before ecology was invented). In most cases, I just punched a hole in the funnel area and did not catastrophically implode. So, with the supreme overconfidence of an 18 year old, I aim for the face of a large round CRT from about 5 meters away. Upon firing, I was showered with tiny particles of broken glass. I also saw the electron gun flying over my shoulder. Fortunately nobody was hurt.

ha, something long and heavy. Line it up to the end of the neck where the plug goes on, look the other way and swing!
Works every time! :)
Do wear eye protection before doing this !
Just run a triangular file across the neck near the base connector and tap with the file, using it like a hammer. The glass will crack and air will leak into the tube.
This is the standard method of cracking and removing the old gun assembly prior to replacing the electron gun and restoring the vacumn.

Tape a Crow Scarer tightly to the tube neck light and retire.
It works for me!

while in a USAF PMEL lab,I saw a guy trying to tap loose a stuck scope CRT from a 500 series scope on a cart,and launched the CRT out the front like a torpedo,and it burst and threw glass all over.No one was hurt,though.

We let the vacuum out of old CRTs by puncturing the anode terminal with a sharp ice pick (actually a ground down Xcelite 'greenie') and a light tap. No broken glass and it feels cool when you put your finger over the anode terminal. Don't know about other tubes as all we have are Sonys.

Back when I were a yoof, and elf 'n' safety legislation was just some petty bureaucrat's eye-twinkle, we just used to take 'em outside, and remove the whole neck with a well-aimed kick ...
Happy days ... :-)

There are toxic phosphors and lead and the boogy man in some of those CRT tubes.

And all those bad things are still _inside_ the tube after the vacuum is let out. Or do you thing that the bad stuff escapes with the vacuum?

I am not an expert.They say Nature abhors a Vacuum.
So, I don't know,,,,,, Turn that vacuum loose,,, and what then comes out?
I don't believe there is any such thing as a perfect vacuum, (other than politicians) even in outer Space. cuhulin ........................... Sarah Palin Rocks! ...........................

Vacuum escaping...kind of like where the cold goes, don't you think?
