there is a template of the design I used for the blade... more or less
Ever just get bored and make something cause you thought it was cool and to see if you could? Well that's how this came about. I don't cosplay or anything but I do love making things. This was actually made a fair while ago ("finished" around Halloween time) I just now got around to taking pictures. Not the best pictures though.
For those a bit curious on the how it was done, I'll try to explain a bit. Obviously I started by gathering reference pics and making a template. (It's a very rough template, but I may upload in scraps. The main material of the bracer portion is made from plain old craft foam you can buy in sheets at any craft store. The foam is surprisingly more robust than you would think, and I have worn it for hours with no trouble.
The eagle and designs were cut out of the same foam and glued on. Originally I used hot glue, which holds reasonably well, but I found super glue works wonders.
The whole thing was then painted with several coats of black acrylic paint, which was watered down slightly. Then the design was covered in several layers of a metallic silver. I went with the black and silver as opposed to all silver as I though it looked more striking and more similar to in game.
The straps are just some cheap leather dog collars glued to the back of the bracer and then secured with another sheet of foam. They were a bit too long and had to be trimed down to the size of may arm with some allowance for changing size if need be.
The blade is something I had been tinkering around with far longer and it is kinda what inspired everything. It extends/retracts via gravity. It was too complicated at this time to figure out a method to extend/retract it. It took a while to figure out what to make it out of, but I ended up using the slats from a plastic blind. They were thin enough and strong enough to allow for the sliding mechanism.
The blade is in three segments, the blade itself, a middle segment, and the outer casing thing. This basically means it's a blade in a box in a box. The boxes are kept from sliding out of each other by little stops, kind of like you would find in furniture drawers. I have seen blades made from drawer slides, I may have to try that one sometime.
The blade is not really secured to the bracer and has no straps of it's own. It stays in place mainly by friction (which is something I mean to change eventually) The paint on it is very rough, and really just to give an idea of how it looks. I may go back and spruce it up later.
That's about it. Feel free to ask questions and what not.
