Nylon and epoxy sux.  no makey, all brakey. 

I'll have to figure out a mechanical means to get that slinky on top of the other coil.

Nylon... not sure what the glue/solvent is that will work on nylon.

The old Airdux material was styrene, which is nicely miscable in solvent. Perhaps styrene or even acrylic which is also able to nicely disolve in solvent??

Of course one might consider Nylon screws?

Use a hot glue gun. I have been using that method to repair BC 610 coils and have had no problem. Hot glue is basically hard wax and seems to be RF transparent. It will booger most anything in place.

Timmy,
          Call me over the weekend to remind me. I have plenty or 1/4" thick polycarbonate or acrylic (lexan) I can cut some pieces to size for you and bring them to the fester on sunday. I know this stuff glues fine with epoxy, I use it to repair coilz all of the time. (or bring me the whole coil and I will do it and send it back to you)

Hot Glue = bad   any place where any heat could happen.

Polycarbonate and lexan, acrylic all "glue" best with a solvent type cement.
So if ur going between any two acrylic type plastics, get some solvent cement out of the hobby shop. The stuff is almost instant acting. (Acetone will work in a pinch, iirc)

Epoxy is ok, but really doesn't bond to a smooth acrylic surface.
If you want a decent bond there, it would be best to seriously rough up the mating surfaces - like with a rough file - so that the epoxy has more surface area to bond and something to "grab".

Also epoxy doesn't do well in a higher temp environment - it gets soft.

Weld the nylon with a solbering iron.

Looks like you are trying to glue Nylon to FRG (the green blocks on the original coil).  They are not close enough chemically that a reasonable solvent or epoxy based adhesive will work.  Likewise the thermal welding of the nylon.

You'll need to make support blocks of different material. Bacons offer of lexan or acrylic blocks is a good idea.  Tyou may have better luck with bonding the acrylic to the FRG.
Alternately you can get 1/2 inch thick High Density polyethelyne stock at stores in the form of cutting boards. Cheap enough and easy to work and generally good at HV and RF ( I used them in Tesla coil applications). High temps is a problem but in an antenna tunna where you want your coils to remain cool, this is no big deal.

As a last resort, there's always the nylon/non-conductive hardware some others have mentioned.

Good luck OM.

possibly drill holes at the ends of the nylon and the edges of the cut-out and use 4-40 brass screws and a small 1/16" thick strap at each end to bolt the support to the green material. Alternately, use small cable ties there. Small hardware might be your friend.

thanks for the suggestions all. Got a hamfester coming up Sunday, I think we will find something down there that will work.  Slab, I'll call you to give reminder. I"M PSYCHED!  I feel like I did back when I was a JN - always something new, something to do, a fester to go to.
