So far we have been trying to stuff a liquid cooling system under
cowls designed for air cooled horz opposed engines.
There are some real kludges out there with two rads and
a pile of spaghetti plumbing.
I am real excited about this new cowl. Perhaps we can find some
body that can make them and sell them. I mentioned it to
Will James but he is pretty busy.
-- Paul Lamar ...No rotor no motor.
Paul, I'd be interested in producing them if
there's enough interest.
Things are progressing on the Nc Mill, but slowly.
I'm currently
waiting on some precision machined parts which are
becoming a bottle
neck.
Anyway, we'll see if there is enough interest in
the mean time.

I think you would make money for years to come.
Will James charges about a $1000 I think for his cowls.
Cooling always has been a big hassle. The right cowl
would go a long way to solve that problem.
-- Paul Lamar ...No rotor no motor.
Jarret, I hope you do supply cowls. The problem is we are all
building different airplanes. If you could figure out a way to cope
with the endless variety, you would have a very good business. I am
not a composite guy so this suggestion may be unworkable in reality.
But what if you required a plywood pattern of the firewall with each
order and you already had made up the complex part of the cowl, i.e.
the nose bowl which would be the same for every rotary installation.
You could also prefab the belly scoop. Then it would be a matter of
connecting and blending blending the firewall shape to the prefab
stuff. Or just make the nose bowl and scoop and let the builder
worry about putting the puzzle together. I would be a customer
either way. Perhaps you could start with just a nose bowl with all
the right openings and see how the business goes. Jerry
Jerry, this has always been a concern when looking
at producing cowls. We know that
for the typical Rv series they are pretty close to
the same and for most models
we can inter-change between them. The issue come's
when people like youself
want a Tailwind cowl, the next guy wants a Bd4
cowl and his buddy is
building a Mustang II etc etc.. I've got some
idea's as to how to make this work
Being as my cowls molds would be built on a CNC
mill, I can easily blend
the tail section of the molds to fit various a/c
while keeping the front section
[even more than just the nose bowl] the same. As
Doc has pointed out, I think
$1000 for a cowl is a bit steep. In reality one
off cowls aren't cheap and storing
10 different cowl sets takes alot of space. A
typical production cowl mold,
when properly built, is 4ft cubed or more for the
bottom half.
I'm wondering if people would be interested is a
"fiberglass FWF package" ?
For this same price I think I can provide a
properly designed pressure recover
duct which will mate to the cowl and some standard
rad size's. If this can be
accomplished then we're starting to get closer to
a FWF package, accept our's
is more a collection of parts from different
vendors rather than just 1 company.
Pretty soon we could just produce a list of
components and where to
buy them and you'd have your entire FWF package.
Some food for thought..
Jarrett
Don't worry about the price. Speaking for myself, I don't mind
paying. Just be fair. The main thing is to deliver a good product
which I have a feeling you would do. Once you establish the ability
to deliver one off FWF packages, you will have a thriving business.
When will the mill be ready? It must be a monster to handle
something the size of a cowl. Jerry
Absolutely right Jerry though I might add don't take deposits if you can't
deliver promptly and then deliver on schedule. A reputation for good work
and on time deliveries would justify the cost.
