I would agree it should be less expensive, and probably adequate
structurally.
But doesn't the bend in the piano wire in the hinge make it difficult to
remove?

I also used the hinge and nutplate method on my RV.- It worked very well,
was inexpensive and only took a couple minutes to remove the whole cowl.

I used nutplates and screws to attach the top cowl.
I take off the top cowl then just pull the pin and the bottom is off.
This method is used a lot by the RV folks.
This is a fairly cheap way to do it.

Thanks. I reviewed the relevant area of the video, and looked up the
fasteners
on the Internet. You're right on both counts: they look like they'd work
better, but it looks like enough to do the XL would cost $300-$400.
However, unless I come up with something like looks like it would work, tha
t
may be the only choice.

| Subject: | A little Help! Muffler -Heat Muff |
Hey folks,
I would like to make my own heat muffs for carb heat and cabin heat.
Dimension are not much of an issue however, can someone tell me what thickness
Stainless steel I should use?
>From some reading I see it is 304 Stainless that is used and in some cases is
Aluminum. Does it matter?
Yes I am trying to save a buck, but want to make it only once.
Thanks,
Rich

Hi Rich,
I wouldn't use aluminum for this purpose. The exhaust gasses get
around 1400 degrees F, and if I remember correctly aluminum melts
around 1000 degrees F. You might wind up with a puddle of aluminum
in your engine compartment.
I don't have easy access to my airplane right now, but I would guess
the thickness of the muffs from the Jabiru FWF was around .020 or .025 inches.

Somebody better tell Aircraft Spruce. http://www.aircraftspruce.com/search/search.php?query=heat+muff&search=1
CESSNA TYPE HEAT MUFF
Heli-arc welded aluminum muff with rustproof stainless steel fins for clamping
to stack.
HOMEBUILDER'S HEAT MUFFS
These superior quality heat muffs are made entirely of 6061 and 5052 aircraft grade
aluminum, offset from the center to clear the close cowling of most homebuilts.

Rich,
I assume you're talking heat-muffs averse mufflers here. For conveying
heat from the muffler to the cabin, aluminum is fine for a heat muff.
I used .025 and wrapped it to a hinge joint. If you're doing mufflers,
you need a .025 or better stainless as the temps recorded 3 inches or so
from the exhaust are near 1350 degrees. You'll probably make two sets
to get it exactly right, so don't scrimp on bought material.
