Chris is off in the land of D/L gliders right now so I'll try to answer this. He sanded the top shape of the spar on the edge of a sheet and then sliced it off the sheet at the width required. After building the wing frame he sanded off the bottom corner of the spar to get the elliptical shape.

  Isn't DT a Wright stuff design, is there a downloadable plan ?

  Ehrn I want to make odd shaped spars, I make a jig with a bit of razor
  blade set over a channel cut in a hardwood block with the blade tilted
  at the angle I want. Works for me, my mentees made equilateral
  triangles and right triangles for their towers that way.

  Built up a practice prop with the formed plastic blades, used quite a
  heavy plastic sheer, cut two 1 1/4 x 4 1/4 blades, nounted them on
  bamboo spars and used 1 1/2" of 1/8 aluminum tube for the hub, weight
  came in at 3 gms.
