feather cut

[spbyrum]

Thanks, Matt.  I have not tried that, but it sure sounds easier than the
way I was trying.

Try a larger harder wheel.  I'm trying to learn, too.  Wings are not too
bad.  Stabs ok, too.  I tried cutting a vertical fin.  That didn't go
very well.  The big difference between root and tip along with the very
short span make it very challenging.

Steve,

There should be a way to use simple geometric principles to cut a very
sort span, highly tapered wing such as a fin. Have you tried anchoring
one end of the bow down, and only moving the other in a circular
fashion. The anchored end will basically serve as the center of the
circle. Depending on where you place the foam blank within the circle,
you should be able to cut a very high taper and short span wih extreme
accuracy.

BTW, this is true for all tapered wings, except it becomes somewhat
impractical for wide chord wing tips, because the circle center is
sometimes 10 feet away from where the cut is made.

Just an idea for you to mull over
