How to release the vacuum in a CRT safely

[AshTray700]

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?

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.

You know what? This guy's just trying to be funny. Hey Curtis, why don't you
go suck a dick, you asshole.

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.

I have a bunch of old long flourascent light bulbs I want to get rid
of.I reckon I will call that Waste Management phone number 601 - 960 -
0000 and ask them what to do about them.

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.
