that story reminds me of my post about "hillbilly frank".he cut the band of a magnavox crt to use in something else.he fired the set up and after a few minutes,i heard a blast like a grenade.the set exploded in his living room.he was on the phone with me when it happened.i have cut off the ears on a magnavox crt but never cut the pressure band.though it didnt pull the nails from the walls,it did leave pieces everywhere.

Why was the band cut off during rebuilding-heat expansion issues?

Yes, when the tube goes into the over the band has to come off because it has to expand or it definitely will go off in the oven.

so I guess the follow up question would be, if a bonded glass CRT has the cataract removed, then why would the CRT not implode upon removal of the bonded glass? Can a band be added to a tube that had the bonded glass (guess before the removal takes place) to be safe again? if so is there a procedure/tools/tension mearuring device that should be used?

Because the glass is just glued to the front of the CRT, it does not impart any tension on the face at all like a band does.

besides the band or safty glass is there a difference in the contsrution of the two?
What I am getting at is "should" a band be added to a CRT that has the safty glass removed. If they are the same basic CRT just one uses bonded glass and the other has a band, then it would seem that a band should be added if the bonded glass is removed. |

when i was about 11 years old me and some of my friends were playing around in a house that had burnt down months before we went in it..
the roof had collapsed in several of the rooms. and there was a large tv in the living room. the case was real wood and i remember the screen looking grey and not black like moden screens.. the tv was atleast 32inches.. we were throwing rocks at it trying to break it.. after all we were kids and the tv was glass... i was throwing big rocks or chunks of cement at it.. it was only scratching the screen.. my friend threw a small rock at the screen and BOOOOOMMMMM!!! it was a amazing sound.. it felt like sombody hit me in the chest. i actually moved alittle from the sound it made.. it was louder than the artilary shell fireworks.. it was definetly something i didnt expect to happen. |
