2 cataract removals of 2 types in 2 hours.

[Electronic M]

Wednesday I finally succeeded at doing an RCA type cataract removal (finally!...the victims of my earlier experiments were stacking up), and to celebrate I did a Zenith type too in a new way. The both came out of a moldy TV shop basement, and the RCA was holding disgusting water from there in the gaps in the glue (tip the tube or pry on the safety glass and it would run through those cracks like some kind of putrid vascular system). I had to get that out to be able to clean it well enough to allow it in the house. The edge bits came loose easy and in big chunks, but the center was on there as good as ever. I had to do the typical sun + wedging method, but by the time I was done preparing that the sun had set, and I had to rely on a 650W photo flood lamp to heat it...It worked great! About 15-30 minutes with it wedged, and the lamp heating the heat collecting garbage bag was all it took to get it to let go. There had to be 1/4 cup of water/dissolved PVA juice in there! One thing that is interesting is that the safety glass appears to be turning into what some glassware collectors I know call 'carnival glass' (that rainbowey look)....It may not be reversible, and I may have to discard that safety glass.




I did the Zenith tube without heating it in the sun or under the lamp. I merely turned on the lamp to see and quickly cut the glue with No. 15 guitar string before it heated. It was fast and easy. I was happy to not need to heat it (that lamp smokes if you let it run too long), and even more happy when essentially all the PVA rolled off cleanly by hand.
