So, not bad. I didn't want to slit the balsa where it curved in toward the front; that, plus making it around the small-radius curves at the back of the form meant wrapping it pretty tightly. That, in turn, means that I now have a nice weave pattern from the Ace bandage printed onto the wood.
Not sure what I'll do about that -- "use filler" comes to mind, but I'm concerned about it slowly flatting out under the filler over time, leaving a print in the paint.
At any rate -- I was clever twice, and that was bad. Clever once in gluing up the wood nice and fast with CA, then clever again experimenting with heating the wood for bending by boiling it. Boiling water releases CA glue -- did you know that?
My wife was helping me wrap the thing; she suggested just wrapping the two pieces -- that worked out as well as anything. I'll need to do some trimming and joining on the bottom side, but it'll work out well. Overall, I'm pleased, and my Legacy will have a nice jet-style airscoop, which is an aesthetic that I like. (To the extent that -- if you can't figure out how it should look, make it look like a jet!)
