Dead CRT disposal?

[Boobtubeman]

Yeah, i was drilling the anode hole out to stick a cord through it. Yeah, you guessed it... was attempting a lamp, folks did it with booze bottles, so i figured what the heck?

Unfortunately, the glass cutter i used didnt cut the neck right and i scrapped the project..

So... did i open a can of worms, anyone attempt this or SUCEED???

Let me know if you figure out how to cut the neck cleanly (hot wire maybe?). I have a couple of dud oscilloscope tubes that could make nice lights.

Today was the day - I had myself wrapped up like a mummy, although nothing dramatic happened. First I sharpened up an upholstery regulator(basically an ice pick) and gently tapped that into the HV anode. The anode metal seemed rather soft, and it appeared that the point of the regulator seemed to be helping keep the pinhole sealed. So I agitated the regulator around gently and could then hear the air softly hissing in. I also had a couple clear plastic bags wrapped around the CRT, so those were possibly dampening the hissing sound. Anyhow, mission accomplished. I really appreciated everyone's input. Not so scary anymore.

It would be cool to see what happened to the picture if you had the CRT running at the time!

I've had the UNpleasure of seeing that happen... I had just finished doing setup on a new tube in a CTC-81 back in the 80s, and I let the back cover slip down while I was putting the screws in... A gentle hiss, and in a few seconds, the neck flashed blue, and then the HV started arcing all over the place as I yanked the AC cord out of the wall. The customer wasn't in the room, so I got away with saying "Seems to be a problem with the new CRT... Back tomorrow with another one no/charge".

As far as self-protection for while you're trying to de-bond safety glass to remove cataracts, (or busting a tube to discard if it's compromised or if you're concerned or inexperienced), I wear motocross gear including chest protector, kevlar pants, and helmet with neck roll & stone-proof goggles.

How awful! All that work setting up not to mention the cost. You were very lucky that you were alone when it happened. An easy mistake to make, I did similar to a colleague's TV. I hadn't really started to work on it, but the back was off and I knocked the back of the CRT and heard the slow hiss. I felt terrible until I priced what the repair would have cost and realized it was a no goer anyway. Still, it's an experience that's not easily forgotten..

After I aired the 21AMP4 I wanted to salvage it's connector, so I whacked at the neck with a small hammer. Could not believe how hard I had to hit it to bust the neck off.
