so, I primed and painted it last night, but the paint didn't want to sit right for some reason. So, I re-sanded everything and I'm all set to paint it again. I did snap some pics in the meantime though.
I wound up hand filing most of the arrow rest in the bow (the bow follows the cutout in the grip) and the notches for the bow string. The notches came out 95% perfect after some cleanup, which I'm fine with since the string will cover a good portion of them. It's also not a very fun project to file through .25" aluminum, and that's really the only reason they aren't 100% perfect. Usually I have no problems filing matching geometry on parts, but the thickness coupled with the weird angle made this one really tough.
I did make the bow cutout flush with the handle cutout. I just never took a picture of it finished I guess.
Now, be careful if you compare the last picture to the promo pic I posted way above. The grip is totally different in the promo pic. In the movie, on the edge of the grip that traces the arrow rest, the further up the bow you go, the more radiused the edge of the grip becomes. In that promo shot in the first post, it's totally flat edged there. That's not the only difference, but it's the big one for sure.
and that's where I sit right now, ready for a repaint.
Oh yeah, the bowstring pictured will not fit this bow, it's just there for show. The actual string will pull the bow tighter together and will be all black, just like in the movie.
EDIT: Also, I am probably still going to have a grip 3d printed. I just wanted to make up this wood one so that I can include pictures of the "finished" bow when I send my plaque to get signed. I'm not going to epoxy it in place until I'm sure one way or the other. I just have to tweak my model a little bit to match with the bow, and everything should be good. The wood grip was also a very easy piece. The whole grip including remaking it (drilled the arrow rest hole after shaping it instead of before, then the drill bit splintered out the top) took less time than making 2 of the string notches.
