I was surprised that my hands weren't shredded by the incident. It would appear that they shielded my face from harm. I only had two small cuts in the palm of my right hand-the one that wasn't holding the paper towel.
Judging by the spray pattern the glass made-it looks as if most of the force was directed towards one side-luckily out of our direction. The shadow mask was shredded, I was surprised, it was made of pretty thick metal, like the kind you would need metal shears for. That certainly worked in our favor as well. All that is left now is the gun assembly, and the orphaned safety glass-in case anyone needs a roundie safety glass.
I wished that hot knife method had worked. But this type of pva was not heat sensitive AT ALL. We got the wire deadly hot, and just for the heck of it, blowtorched it just below the melting point, and it still did absolutely nothing to the worklight-softened PVA.
Now, I have another 21fj that is cataract-free. I have that installed already, and I had a miserable picture on it. All but the green gun tested as bad. After letting it cook at 8 volts, the other two guns came up, and now I have a crt that tests largely good, with excellent tracking.
But now I had some arcing in the hv cage, and I could only crank up the hv to just under 20kv....
