Recurve Bow Limb Geometry

I'm a week new to Fusion 360 (and CAD software in general) and looking to model this bow limb so an event simulation can be applied to it. I can't seem to fix the mesh geometry though. 

If anyone could point me in the right direction with fixing it (you'd probably have to look in the project linked, I can't quite explain whats wrong) it'd be much appreciated. 

Also, I've been trying to project the sketched limb profile onto the extruded spline but I've been having no luck, which lead me to just intersect it (which isn't ideal - I can't figure out how to make it the exact thickness I want). Any guidance there would be nice too.

 If I understand you right, you want to extrude from an object. If so, here is a screencast :
