RCA cataract removal

[Radiotronman]

I agree that the clear silicone and clear double sided tape is definitely the way to go. If you do it neatly it will look just like new. Here's one I did last year.

It's not terribly expensive, it would bond the entire safety glass to the tube, be completely clear, and - I imagine - offer some implosion protection, as versus nearly none that the bead of silicone around the edge offers.

I looks like the orig system was to install the glass, use tape to seal the edges and then inject the liquid thru a small plastic port. Not sure how the glass was maintained a consistent distance off the CRT face. I did a quick of a 20x20X.1 volume of 40cubed inch, about 22 oz. Not sure if its sold in bulk for that kind of delivery.

From what I can find, cps stands for centipoise, a measure of viscosity.

Maybe fasten the glass back on using a few small evenly spaced pieces of double sided tape, then follow up with a fine bead of caulk around the outside to seal the dust out, or maybe even just use clear tape. I highly doubt silicone caulk will add much implosion protection. I'm thinking avoid the whole caulk mess.

I just use the foam tape, single side sticking, go all around the glass (not the crt) and use packing tap to hold it in place. The foam tape spaces the glass off the crt, keeps the dust out.

Another Dave here....I was in a hurry and used what I had which was white silicone. I will be re-doing the attachment as it did spread inward so that it was seen at the sides of the 21" round tube.

Tom has the right stuff - GE clear silicone and I just bought some, maybe because I'm working on a GE

Just got through doing the RCA Colorama with the Zenith style halo. I used a heat gun, and about an hour and a half of my time. I had to force the wooden pieces in between the glass, and amazingly, nothing broke. I got the glass off just fine, with LOTS of heat. And yes, the green stuff smells like burning piss. I'll take the RCA style any day over the Zenith style.

No need to run current through the guitar string or heat it....I've done cold guitar string zenith cat removals, and they work as well as hot does. Interesting that the heat gun method works, but I would still not recommend it due to the implosion hazards involved in the heat gun methods uneven heat...I've had RCA CRT faces crack from being unevenly heated by the sun so I'm a bit less of a fan of heat based cat removal methods than some.

I've always thought it smells exactly like a brand new out of the box inflatable pool toy....Magnified by like 30X.

Happy memories of my youth! Every time I get a whiff of that smell it reminds me of when we went to the Sinclair station to gas up Mom's car in the 1960's. They used to give away inflatable Dinos with a fill-up.

What did you say about implosion? I took care of that prior...
