What a piece of wood! John you sure do a great job of takin pictures all along the way to keep us posted on your progress. Wish I was better at that.
Now about the bow (got ur pm BTW,) you got a ton of wood to remove. belly handle and sides, if you want. I would start with the belly and get it to floor tiller. Be extra vigilant around that big bend as a spoke shave tends to want to peel more wood off there than you want. Probably a rasp is best around that curve, both on sides and the belly. Once you get it bending evenly aroung that big bend teh bow will start coming together fast. Leave the limbs and the tips wide up to the end and then you can play with width or string alignment a little.
I'm curious, what weight are you shootin for and how is the concavity of the back looking now that you have the bow laid out.
Keep taking pictures and... try to get some sleep!!
