It's finished! I finished my hickory recurve! It's not the best bow in the history of the world, and sure, some things could've gone better, but in the end I'm actually pretty happy with how the thing came together. It's not going to be given as a gift as originally planned, but it was good practice.
Final specs:
-65" nock-to-nock
-43# @ 28"
-limbs are 1.5" wide tapering to less than 0.5" at the tips
-about 1.5" of set, but 2" recurve more than makes up for it
-working handle (I put a layer of rawhide on the belly of the handle section, and built a wood handle on the back of it, then slicing through the riser wood down to the rawhide in 1/4" intervals to allow the riser to bend with the main wood of the bow. I don't recommend doing it this way, but it works.)
-the tiller is a little off, though that's partly a visual trick due to the larger part of the handle sitting on the lower limb
It's a really sweet-shooting bow, and I learned a lot in the building process.
