<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>

<DIV><FONT face=Arial size=2>If your model is not destroyed taking it out of the
mold, you spent too much time on it!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </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>

down).</FONT></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><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any insights much appreciated....thanks in
advance.</FONT></DIV><FONT face=Arial size=2>
