Hey all, thought I'd share my 2016 Halloween project here. I finally decided to do one I've been thinking about for awhile, the Alien Xenomorph. The inspiration is mainly the original Big Chap design from the 1979 film, but it's a bit of a hybrid as I'm incorporating elements from the Alien Isolation and Aliens xenos, and possibly more.
As in my past builds, the idea is to make it so I can 1. Put it on/take it off myself, 2. Function at a Halloween party (including having a drink and taking a bathroom break), 3. Get around without being an overall nuisance, and 4. Transport it if needed without taking up *too* much space. In my past builds (Gears of War, Iron Man, Groot) I have attempted this as well, although my success has been limited.
For obvious reasons, I started with the head. First I should mention the ideas I considered and abandoned. I wanted to do the clear dome with skull and detail underneath, but I don't have a vacuum former or experience with acrylic and I figured with the size of acrylic I would need for the xeno's giant head, this was not the time to experiment with that. I also had intended to have the inner jaw/tongue be electronically activated, with servos for the jaw. I got the wiring working, but realized I just wasn't going to make it all fit in the head I built.
The plan began with using an old bicycle helmet as the base and building the head around that. I sawed off the sides as I wanted to make it as sleek as I could and still fit on my huge noggin.

I had originally intended to have layers of insulation foam and sand it down to the shape I wanted. I then realized it would be difficult to mount the helmet in, as I would have to hollow it out as well. So I switched gears and found a pepakura file somewhere (unfortunately do not know the author) that had a good base for the top 'dome'. I switched to EVA foam, as I have a lot of the puzzle floor mats left over from previous builds. The file also had a pattern for the lower part of the head, but I didn't like the way that turned out so I only used a few pieces from that. I made my own side panels, which I based off the NECA action figure.

I added in the cheeks and lip (from the scrapped pepakura bottom piece) and the top row of teeth (from my own hand sketch).

I mounted in the helmet. It is secured in place with zip ties, paracord, and hot glue.

I worked on the bottom jaw. The plan is to hinge this inside at the end. The base design is from the scrapped pepakura piece, with my own teeth and other modifications.

I added in the details to the top piece. I used a combination of different kerosene siphons for the middle assembly. The thick ridged tubing is sump pump hose... $8 for 24 feet and I'm using it in multiple spots. Also used some flex tubing, some braided cord. Some of the details aren't 100% accurate, but I feel they sell the original effect nonetheless.


And finally, here is the plasti-dipped piece in black.

I wish my dome edges had turned out a bit smoother, but I think the overall effect still works.
Tomorrow I'll post my work on the inner jaw and other pieces.
