"Recently someone posted a link to a picture showing how they had built a jig setup to cut the taper using what appeared to be a wood rasp.?
Jim, I picked up a partially completed plane with the spars pre-built. I didn?t think about the airfoil taper until it was too late - after the spars were in place and foam glued in (along with fuel tanks.) I used a hand plane to shape the spars, and while it is a little more effort than a table saw and jig, it produced really nice results. None of the pictures on my blog highlight that very well? because it was a small step and really easy to get right. Just do yourself a favor and sharpen the blade OFTEN. -Matt http://kr2pilot.blogspot.com/
