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
