Default How to release the vacuum in a CRT safely

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?

drive a small screwdriver blade into the hole in the end of the CRT 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.

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!

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.

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.

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!

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 ... :-)

You shouldn't breath/inhale whatever is inside of those tubes.

Yeah, vacuum is dangerous to...uh, breathe?



You can see what it did to him.

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

Swing a piece of wood or a hammer across the neck while looking the
other way .
