One of the final pieces of the puzzle was the small plastic piece that fit around the edge of the mask that faces the CRT. This is to give a nice appearance rather than just an edge of sheet metal. This piece is "J" shaped with the smaller side visible from the front of the TV. I tried several times to find a suitable piece of plastic to no avail.
I then thought of a small piece of silicone fuel tubing that is used on R/C airplanes. This tubing is translucent in color and very flexible. Hmmm......
The stuff I used was 2mm I.D. and 4mm O.D. I had to split is down one side. I made a jig so that I just inserted the tubing into the jig and I then just pulled it through. Perfect!
I then slipped in onto the mask, cut it to length, and then used some medium super glue to hold it in place. This worked out very well.
