RE: [TCML] CRT wire - harvesting safely

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Brian,

On older b/w sets, we used to hammer a screwdriver into the end of the
electron gun. This may be harder now as the necks are thinner. You probably
can remove the focus clamp etc and then the yoke if you are careful. In any
case, be sure to wear goggles or better yet a safety shield.
I did this with a PC monitor recently as I scrap out copper. I was surprised
that the yoke was wound with two sizes of Litz wire and was easily unwound
:-)I won't be scraping that out!

Careful is essential like most of the hazards we deal with. Anyone with
current vacuum equalization experience please chime in for my benefit too.

Subject: [TCML] CRT wire - harvesting safely


 

I managed to get the CRT out of a little old portable TV, with a 4 by 5 inch
screen, and it has lots of lovely copper wire that I want to get out and use
for a secondary coil.  I know these tubes are under a vaccum of sorts and I
will have to melt off a bit of glue and bend off some posts with pliers, so
should I pop the tail end of the tube before I start trying to extract the
wire?  If so what is the safest way to pop a tube or otherwise get at that
wire?
