Well, good news, bad news, good news.
the bow arrived today, but it doesn't look like it's gonna work. the edges on this bow have like a .25" (radius) rounded edge, and there's not enough material to just remove it and have it look right. I may still make up this bow anyway, and bondo the crap out of the handle (not the round edge, just the front where it's supposed to be flat) and have this be a functional replica or give it to my sister. It would still look great to the average fan, and way better than the pse snake that is being sold as a replica on the site I linked earlier. I'm a bit more anal retentive than that, so it has to be done right for me.
As far as I can tell, there's 2 props in the movie (at least). An aluminum bow, and a painted fiberglass or wood one. At first I thought it was just my imagination, but this picture looks too convenient to be just good editing. They probably also have one of each in the permanently drawn position. Some shots need a bow like that while others could just be drawn and fired. I read they had a regular and permanently drawn bow for the hunting scene at the beginning of the movie, so it's not a stretch to imagine they did the same here.
There is some serious sheen there.
Then, any time the bow is seen being drawn, it's clearly a painted bow.
So, not to be discouraged, I've got 2 options here. I can try to bend a non-functional bow out of aluminum, or I can cut one out of wood. I'm not going to blindly try bow after bow, and even this one I have now with a good number of pictures available looked right, but when I got it, it wasn't even close. Obviously, cutting one out of wood is not an ideal scenario, but if it's what I have to do, I'll put in the time. No sense making one that's half right and then redoing it later when I decide I'd rather have accuracy.
Also, I found someone to make a nice custom plaque for this that I'm going to send off to be signed.
So, that's where I stand right now. Either way, I'll be doing more research tonight and fully blueprinting the design that needs cut or bent. Heck, I could even make one out of fiberglass like I did my armor, but I don't see the point in that. It still wouldn't be functional.
EDIT: Here's my 1:1 template. Still not sure how I'm gonna make it yet, but I'm gonna give it a go
And there is the template vs the bow I bought.
