I found that it took 66 Aluminium heatsinks from CRT's to make a Kg of aluminium. YMMV
'Extrusion Aluminium' pays more than 'Domestic Aluminium' by about 40%
CRT tubes will explode if handled wrong, one single instance of this can be life ending, income ending or life changing. Do not underestimate the vacuum in a CRT tube.
I would put the TV face down on something soft like as couple of layers of carpet, remove the back of the case and cover the TV with heavy cloth and then thru it, grab the board on the end of the tube and wiggle it like its a cars steering wheel. Until it cracked and let air into it.
After that, its as safe as a very sharp oddley balanced 50lbs of smooth solid/sheet glass can be.
I tried to lever the band from around the screen off, while it still had vacuum in it.
Bad Bad Idea....
It exploded making a 12 foot diameter circle of sharp shards of glass about 1 inch to 8 inches long.
How it missed me, I have no idea. A true miracle really.
