I agree. Someone
Great info. I guess my point to the original question/comment was the designed
material was not easily found or within a reasonable price. The drawings still
shows .005 stainless and asbestos on the firewall. Maybe this dialog will
bring about some sort of addendum to the drawings with a
We're NOT certifying under Part 23. The info I provided was in response to a

I should probably clarify that the exact type of aluminum doesn't matter
much, given that it all melts at about the same temperature. I'm guessing
Tony recommended 2024-T6 because it's a little stiffer than most others and
would look better, but if you've got any kind of .015" aluminum around,

I am pretty sure that you can get thin galvanized at Home Depot. Any
local sheet metal place should have it also. I got a 4' X 8' sheet of I
think .016" when I redid my Sonerai and Starduster firewalls. I think
it was something like $30. Aluminum will not block a fuel fire for very
long.
How much is the Stainless and Fibrefrax firewall kit ? Virg

FYI. Neither wicks or aircraft spruce carry .005 stainless sheet or any other
size below .015. I found a specialty supplier in Ashland Oregon and they want
$63 per sqft. A touch spendy for me. Fortunately I have a piece coming from a
generous KR builder. So for the other new builders out there,
Wicks or Aircraft Spruce, Virg

Hey guys,
Over here in the Netherlands we are bussy with the fwd deck, canopy frame and
the aft deck. If I am looking at the next stage we have to think about the fire
wall. We have made the decision to go for an 100 HP engine. Did any of you make

Hi folks,
I have a question. I've been using T88 epoxy and decided to try
Aeropoxy PR2032 Resin with
PH3660 hardener. I glassed a part of my elevator with it three days
ago and, although it has
set up and no longer tacky, it is still flexible. I can still indent
it with my finger. Is it
McMaster Carr sells various thicknesses of thin stainless steel. I used
some .005" for some of the "NACA duct" protection from exhaust heat that I
put under those ducts. See

.005" is $42.05.
Also, a 2'x3' piece of
Some folks asked where to get Fiberfrax. See
http://www.aircraftspruce.com/search/search.php . I think I used 1/8", but
1/16" is supposed to work fine. I guess that's another reason my plane is
heavy, although fiberfrax is a tiny fraction of the weight of stainless
steel, and that was my
Hmmm that is true, though I do have a real small tank too so there is alot
of weight savings there. Guess it all depends on several factors. I guess if
I was going the two place route I would worry more about it as tyring to lug
300-400lbs of humans then every single pound saved counts.
I won't
