Looking to put a heat blanket on the top of the tail fuselage. Obviously from the pic the tail pipe will be touching the top of the fuse in
this plane (BD-5) due to modifications recommended by others. The pipe its self will help hold the blanket at the very end but as it
moves forward what would be the best way to attach it. I know epoxy gets soft with the heat. Would a resin mix work
if applied like it would be if you were adding a layer of fiberglass, then lay in the heat blanket instead? Ideas ??

Thanks

Aluminum tape

I've had a lot of luck using RTV silicone to hold heat blankets in place . Just lay a bead all around the edges and a few beads in the center. I used to use aluminum tape but found that after a year or two it would let go leaving a sticky gooey mess.

I've had the same problem with the alum tape. Don't want to stick real good, even with prepping the glass, then the heat does in the glue.
Now the high temp RTV silicone,,,,,, haven't tried that

Thanks.........

+1 on the High temp RTV. Have used it for years on installs.

Yep, as Dean and Jim said, high temp. RTV silicone. Get it at your local auto parts store...

Here's what to look for:
Also, use the search feature to find my article entitled "Fabricating a thermal blanket".

Automotive high temp RTV works great just clean/prep the surface. The aluminum tape doesn't work that well the automotive version of the aluminum tape sticks much better than the stuff you get from bvm/dreamworksrc.

What I like even better than RTV is Permatex Copper Spay-A-Gasket.

It's normally used to position automotive engine gaskets and hold them in place. Use it like contact cement. Just spray some on the ceramic blanket and a light mist on the fiberglass, wait half a minute and press the blanket in place. You can get it at most Auto Parts stores.

After installation cover the ceramic blanket with aluminum tape.

I've done this on several planes, and it's held up well. I am a bit concerned about your pipe touching. It's best to have some air gap around the pipe. Maybe you should invest in a smaller diameter pipe.

I sandwich the the heat blanket with HD aluminum foil (heat blanket inside and aluminum outside). The aluminum foil helps the heat blanket to holds its shape and then use the RTV silicone as Jim stated to attach the fuse.

Works real well....

Just do what the BVM rep says , they had it figured out a generation ago .

I just use the heat shield paint, put wires in split plastic loom, paint the loom with heatsheild paint.

Harley,... Never read your tutorial, but I will read and take note ... I learned that by having several BVM jets over the years...
