A Bundle of Studies and Doodles






In order from most recently finished today (top) to older (bottom): some select doodles, studies, and permanently unfinished works from the past couple of years. I never share all of my art, especially since much of it is simply studies, however I wanted to highlight a handful of the drawing and painting practice pieces I've done as it's been a minute since I've updated this page.

Alien Cosplay 3.0 - Build Log

I have created a new Alien "Big Chap" costume to wear at 2019 Dragon Con!


The entire build has taken several years due to life events hijacking my project, however after months of hard work and plenty of failures, I finally have completed my animatronic Alien costume. This is the 3rd alien costume build, and the first "real" cosplay I have attempted to solo build after learning more about cosplay fabrication methods from my friends and peers.

This costume was built upon the amazing Pilerud Cosplay's RPF progress photos, which were made freely available back in 2017. While he does not include a "how-to" or step-by-step for his costume, he has plenty of WIP pics and videos that show the components broken down to their basic parts. He was also very open to answering my questions when I reached out to him online.

His patterns helped me realize just how I can shape and form EVA to create complex organic props and armor. But while the basis of my alien was built upon his plans, I did several things differently, including re-shaping the tail, changing the chest and ribs connections (which need another revamp), overhauling the patterns for the dorsal pipes to include a bend, and using epoxy resin vs. polyester resin + woodglue to coat the props. A lot of this build was also trial and error in figuring out what would work best for ME based on the materials I had access to, and my own understanding of manipulating them.


Cat nephew Calcifer providing moral support

I cannot thank the support of my friends at Overworld Designs and MakingItUp enough, they were very supportive of me and this build over the years and I would have never known where to start had it not been for them introducing me to all of the different materials that I have used in this costume! They also only made fun of me a few times for working on alien costumes for 5 years!

And finally, I want to thank my amazing mom for being awesome and helping her adult daughter sew her weird monster costume's neck piece, hands, gloves, and nylon connections. I also want to thank my dad for giving me an extra hand in mixing the plaster for the dome mold and for assisting me in dumping gallons of boiling water into a giant dye tub, and not really questioning it.







FAQ:

How long did this build take?
I started this project years ago, however scrapped a failed build as I was learning materials the hard way as I went. Due to infrequent opportunities to work on the project, life events, and my own laziness, this took me about 3 years to complete. You can build this in less than 1.

How much did this costume cost?
For my own sanity's sake I have stopped keeping track. The epoxy coating, the PETG domes, and the EVA and pink foam were the main components of the costume that took a lot of money upfront, however all of the tools, glue, paint, and smaller components added up quickly overtime.

I would estimate over a couple of grand was spent, however this was due to my own inexperience working with certain materials and scrapping a previous build. You can do this cheaper if you know exactly what you're doing and if you have access to many of the necessary tools already.

How did you make the clear dome!?
The dome was vacuum formed out of clear 0.08" PETG plastic on a large-format vacuum former machine run by the amazing folks at Studio Creations. They were enormously helpful in guiding me towards creating the proper buck for my build and I could not have achieved the clarity on the dome that I did without their advice. The buck is a huge (and heavy!) plaster cast that was coated in EpoxAmite and sanded and buffed to a glass-smooth finish. You can see the forming in action here!

Can you see?
Yes, but not easily. I can see out of the skull eyes, and down through the bottom of the jaw. I need a handler for this costume, especially since it is warm, I'm wearing heels, and my head/chest/tail stick out from behind me and take up extra space. I have no peripheral vision.

Can you breathe?
Yes, I have small hidden slots along the sides of my costume where my face is that allow for more ventilation in my helmet, and there is ventilation under and through the jaw!

Is the tail permanently attached?
No, the tail can be disconnected separately to a mount plate under the suit for easier storage. My cosplay can be broken up into the following individual pieces: head, neck cover, chest, dorsal pipes, suit, gloves, glove cuffs, tail, and shoes.

Can I buy the costume/are you taking commissions for this costume?
No, but I would be happy to share my experiences with building this costume and would be more than happy to answer your questions. I do not do any cosplay commissions since this is just a side hobby for me.

Have you done other cosplays?
Yes and no. This is my 3rd cosplay, however this is my first "real" solo build after doing work with my cosplay friends and absorbing a lot of knowledge from them. My last 2 cosplays were also aliens... I just really wanted to get a version with animatronics working. I'm ready to do something else!

Tools:

I used a huge variety of tools to make this costume happen. While not all of these are necessary, some of them certainly made the job much easier for me for the methods I used. I won't list off every tool that I touched for this project, but some of the more notable ones are:

Hot Wire Foam Sculpting Tool
- Basic block sculpting of the head

Boxcutter
- I carved the majority of the head base with this when I needed more control, as the hot wire cutter could very easily cut away more than needed

Power Drill Large Sanding Drum Bit
- For smoothening out and sculpting the pink foam head base

Large sanding drums for a hand drill were used for sanding the pink foam base sculpt

Rotary Tool/Dremel
- Sanding bit for majority of small EVA foam sculpting
- Tons of other bits for various sculpting or drilling work

Leather Double Cap Rivet Tool
For mounting the leg support tail straps to the aluminum plate (allowed the straps to pivot)

Large Rubber Mallet
- For hammering the aluminum butt plate/tail mount into shape
- For hammering the double cap rivet into the aluminum plate for the extra leg support straps

Belt Sander
- Cheap Harbor Freight sander for large EVA piece sculpting and smoothing the teeth sculpts

Sewing Machine
- Stretch needles for the 4-way stretch fabric
- Heavy duty needles for nylon strapping

Giant Plastic Tubs
- For plaster mold pouring using my cheap risky method
- For dunking PETG domes into dye bath

Duct Tape Dummy
- For modeling the morph suit as I glued details to it

A duct tape dummy or dress form is invaluable in making sure your patterns are correctly sized and shaped.



Animatronic:

My main reasoning for revisiting the Alien again for a cosplay was to finally accomplish the moving jaw mechanism. The only electronic components to the head involve moving the tongue; the outer main jaw is puppeteered by my own jaw. This means that when I open my mouth, the chin elastic straps pull down on a wire that pull down on the prop jaw. A smaller elastic strap under tension pulls the jaw back closed. This means that the head is NOT actually supported by my chinstrap, but completely by tension against my forehead with helmet padding! Without enough padding to support the head, the jaw strap cannot work.

Animatronic tongue schematics. The push buttons were replaced with limit switches for ease of use.

When the mouth is open, it triggers a limit switch to turn on power to the tongue mechanism. Once that is on, I can press another limit switch with my tongue to make the alien tongue move. The first switch prevents the battery from running constantly and saves me power at the convention. Pressing the second button moves a servo in the back of my head that pushes a brake cable all the way towards my front and pushes out the tongue sleeve over a tube. Pressing the button with my tongue frees up my hands from having to operate the animatronic and it also makes for a fun story when explaining it to people.

Not included in this video is the E-Z Connector that I eventually used to connect the brake cable to the servo horn.
Without this connector, the wire would get caught on the horn after some time.

My original plans for the tongue were to be powered by an Arduino, however even the small micro-controller was more than needed for a simple servo sweep motion. I moved away from the Arduino design after consulting with Pilerud Cosplay on his own mechanism design that used the servo tester instead. I feel that with a simpler controller, the build is more solid and I do not have to deal with the servo jitter caused by the Arduino.

For more schematics and photos of the jaw mechanism, check out my download link at the top of the post!



Storage:

I store my entire costume in a large rolling toolbox. I decked it out with a few custom laser-engraved aluminum data plates, and a spray-painted logo. I highly recommend the rigid toolboxes for storing your costumes all in one place! They are available in different sizes depending on your needs, and the hardshell frame is perfect for protecting your cosplay during storage and transport.



If you took a pic with me please send me a note I'd love to see it! And stay tuned here or at my Facebook or Instagram for more details on this build and future builds! Thanks!
