[R-390] Filter Repair

[quartz55]

OK, I tried stripping a long piece of 1/2" hardline and razored off a long piece of foam to the center conductor.  It's a bit narrow and somewhat stiff and cracks when I bend it tight enough to go around the copper cup.  It may have to do.  I'll try a couple pieces if I can get it to wrap and glue on the cup.  I wish I could find a piece of 1/2" tape of the stuff.  I found the Gortex stuff, but couldn't find anyplace to get some samples and real buying of the stuff looks like $$$.  Plus PTFE does not glue very good.  I have strips of PTFE, but it's not expanded, just hard strips, but it's flexible enough, but again glue doesn't work on the stuff.

I did try some packing foam PE but it melted immediately upon giving it the heat gun.  That wouldn't work.

Got news of herniated disk and nerve impingement today, so laparoscopic surgery in the plans next week.  Ugh.  Layup time may extend through the summer, but not flat down, just walking back into life.  I was wondering why my left leg hurt and felt so weak.
