Thanks. There has been a lot of effort into this machine. I want to get the lacquering out of the way while the weather is good.

Looking forward to testing the completed chassis in September.

I must agree, a labour of love for sure. I too look forward to seeing a picture!

I finished the cabinet this evening. Two coats of lacquer: first coat, 400 grit wet and dry paper rub down, second coat, 600 grit paper followed by 0000 steel wool. The cabinet looks quite respectable now.

Before I head back to the chassis testing, I have run into a problem with the shadow mask. The black rubber surround seal has melted and amalgamated with the shadow mask. I tested removing a small portion at the corner with alcohol aided with a razor blade. The alcohol dissolves the red-brown paint. I dare not use the razor as it easily scratches the paint.

Any suggestions how to remove the rubber without removing the paint?

This may be a shot in the dark.

With the Motorola 7" VT-71 sets, that gray rubber CRT surround molding will easily be removed with plain water. Have you tried that? The RCA rubber may not be the same rubber type.

But water, in sparse amounts, might work; might not.

The water works! It takes a little soaking but it dissolves the rubber without disturbing the paint!

Thanks for this. Lesson I keep relearning is to try the simplest things first.

Excellent.
