I've got the lost magneto wire welded back in the 4K filter, but as I say, it's a #34, not 40, and the bobbins installed and glued.  But what the heck.  Anyhow, I'm pretty tired of it today, I've need to cut some more foam PE from the hardline. I find it's easier just to take the soldering iron to fasten together the pieces of PE, RTV doens't stick, but then I'm using 5 minute epoxy to attach the PE to the filter bodies and the bobbins in the copper cups.  I've got all the dimensions for all this stuff and I'll list it later.  But here's where it stands now.  I notice the bobbin wires seem to have lost some of their covering, so I'm going to mask them and spray them with some enamel so they don't short out when I install everything.  It's just a matter if getting it back together now and see if it even works.  I'm sure soldering those #40 wires on the end caps is going to be challenging.

I haven't been looking foreword to winding any of those bobbins, but hopefully between all the old filters I have and the broken ones, they can be re-used.  They don't seem to be different at least between the 455 models.
