John Ferrell described a technique for obtaining air inlets/scoops. It looks
like fun for people who like new and different adventures in modelling. However,
I prefer my technique: contact Mike or Maureen Dunphy at Precision Aero
Composites [phone:(662) 462 5480, e-mail <a class="moz-txt-link-abbreviated" href="mailto:mdunphy@avsia.com">mdunphy@avsia.com</a> or internet: <a class="moz-txt-link-abbreviated" href="http://www.precisionaerocomposites.com">www.precisionaerocomposites.com</a>]
and order a set (3) of their Bolly NACA inlets. I plan to use a set on Tony
Stillman's new Panacea design, which Mike and Maureen will market and will
also be using a pair of the Bolly F3A carbon/kevlar wheel pants, which they
also sell. <br>

<div><font face="Arial" size="2">If you would like to dabble a bit in a
small glass project scoops are an ideal subject. Just about any epoxy will
work well. Check out the spoons available in housewares (avoid the kitchen
drawers unless you are batchelor or want to be one). You can make the mold
using a carved up spoon, play dough, paper mache,wood scraps, balsa or whatver
your imagination will provide. I like to hold the stuff together with hot
melt glue.Avoid polyester resin because it will probably get hot enough
to melt your mold. If you don't happen to have any suitable glass fabric,
scrap from the rag bag, or a handkerchief will do...these are not structural
parts. Use some kind of wax for mold release, I like paste floor wax like
I use on the table saw. Try to avoid a wax with silicon, it will be very
hard to paint otherwise. After waxing, spray with with hair spray.</font></div>

it out of the mold, you spent too much time on it!</font></div>
<div> </div>
<div><font face="Arial" size="2">When you do the lay up, wax the mold at
least 3 times, polishing each time. Spray liberally with hair spray. avoid
runs, they will require filling in the part. When you start the lay up in
the mold first paint it with a thin coat of the epoxy. That will assure
a passible finish. It takes longer, but small scraps of cloth are easier
to fit in place without wrinkles. try to make the fabric cuts at 45 degrees
to the threads, it will conform to the curves easier. </font></div>

Scoop-Making</div>
<div><br>
</div>
<div><font face="Arial" size="2">Decided I want to use a scoop on my
latest for crankcase/bearing cooling. I know where to locate it on the
cowl, but have no idea of shape, angle, if any "ducting" is needed. It
looks like the scoops out there just direct air based on their shape alone...without
ducting.</font></div>
<div><font face="Arial" size="2"> Anyone have any suggestions/ideas
on this?</font></div>
<div><font face="Arial" size="2"> What to make the scoop out of?</font></div>
<div><font face="Arial" size="2"> And how to determine what size
is "right" ?</font></div>
<div> </div>
<div><font face="Arial" size="2">Any insights much appreciated....thanks
in advance.</font></div>
