This is an example of what I was blathering about above with regards to profile plates. These are rejects, but they get the idea across. The lower profile is too long, it was supposed to be 3/8" from the edge of the cylinder to the nose of the airfoil, and I botched it. So once I like the look of the two profile plates tacked in place, I'll sheet the outside in 1/64 or 1/32 ply, build the outlet and inlet as needed, fill, putty, sand, massage, tweak until it looks like a speed cowl. Then make the parting plate, then lay up the mold, oh goodness what have I gotten myself into...
What am I complaining about, at least I didn't have to make the airframe.
