Thanks, gentlemen.
Stickman - I heated the curves into the tips with a form, clamps and heatgun. Was originally going to go with a heavy curve, but once I started curving the tips, I liked the very subtle look better.
Mohawk - I used loctite gel super glue for the tip overlays and for gluing on the arrow rest. I have a hard time getting the surfaces perfectly flat to mate, but I made it work. I'd imagine you could wrap part of the overlays with sinew if you're worried about them coming off. Little extra insurance never hurt.
