February UFO Sightings in the Workshop

 I've been getting way behind on bloggage again.  As usual it's because I'm completely buried under an avalanche of UnFinished Objects in the workshop.

So in order to give you an idea of what I've been working on (instead of sitting down and actually writing anything worthwhile) here's the latest round-up of works in progress...

First up, there's this pair of alien taxidermy mounts that I've decided to dust off and drag toward the finish line:

The Xenomorph head is a leftover from Jazmine's magic wheelchair project (LINK) which we built years ago.  I've been wanting to mount it on the wall ever since, but hadn't gotten around to finalizing the sculpt for the neck and shoulders.  

The massiff was a 3D sculpt by Sean Fields that I printed and molded years ago, but it was overcome by events and I never got around to sculpting out the mouth parts to go inside.

Now both of these are going to get finished pretty darned quick.

While my 3D printers were sitting idle, I decided to have one of them turn out a Gungan skull:

This has started me on a kick making all manner of alien skulls.  More on that later.

Next up, I decided to dust off my giant pet bee project and tune up the parts for molding:

Banana for scale, but I ate it.

On the subject of completely random projects, I decided to make a 1/12th scale model of the MkII PBR (Patrol Boat, River) like the US Navy used in the Mekong Delta in the Veitnam war:

This is the same kind of boat that was made famous again in the movie Apocalypse Now.  I'm not sure what prompted me to start this project, but I'm at the point where I need to install jet drives and radio control gear and it'll be ready for sea trials before I finish all of the armaments and details.

Getting back into my usual cosplay lane, there's this beauty:


This is the Horde emblem worn by the forces of Hordak, the villain from She-Ra.  His top lieutenant was Shadow Weaver who wore this emblem on the front of her belt.  So now it's up to Rachel to get the rest of the outfit together:

Also on the subject of cosplay projects, I'm nearing completion on my Warhammer 40K Techpriest build:

The collar and backpack are fiberglass since they'll have a lot of other parts mounted to them.  That said, my first raw cast copy of the backpack weighs about twice as much as I was aiming for:


So the second copy will probably come in around six pounds or so.

Speaking of changing the subject, I was thinking of other ways to get more out of the little alien vagrants I brought to Neotropolis last year (LINK).  So I decided that I needed to scan their parts and print them in miniature:


The heads and hands will be grafted onto some tiny dolls I stocked up on:


I've been approved as a vendor for Neotropolis, an upcoming cyberpunk-themed immersive event down in the Mojave desert.  So I'll be opening an alien pet store and now I need hurry up and generate a whole bunch of little alien critter props to sell on site:


We've launched a Kickstarter campaign to cover the initial material costs (LINK)

And I'm making new pests to hunt down as an exterminator once we get there:


Stay tuned for more on that.

BATTLECAT! Xuan's Magic Wheelchair

A while back I posted about the build we did for Meredith's Skeletor Throne we built on behalf of Magic Wheelchair.  I mentioned a the end of that post that we actually ended up building two Magic Wheelchair costumes in the shop simultaneously while the Magic Wheelchair team in Portland, Oregon cranked out two more.  

I suppose I was feeling a bit cocky when I said, "Skeletor's throne will be easy.  Give me another one too."  But that one ended up being the Battlecat we built for Xuan:

To see how it came together and some photos of the happy kiddo after the reveal, read on...

Genestealer Update 25: A Very Handy Critter

When I last posted about this project, we'd almost finished sculpting the hands. 

My friend Jeff Santos had done most of the sculpting on the upper hands:

And my friend Walter Welsh had done most of the sculpting on the lower hands:


After letting the incomplete sculpts sit on the backburner for a few months, I dusted them off and gave them some finishing touches prior to molding. Here's all four finalized sculpts sitting on the bench:


For molding each one had a parting wall built up around it with water-based clay:


Then one side was given a thick coat of epoxy-based gelcoat:


All of the hands were handled in the same manner, so I'll end up showing photos of them interchangeably:


I was very excited to be back to making progress on this project:


Once the gelcoat had set up, additional thickness was built up using Plasti-Paste Epoxy:


When that had cured, each piece got a couple layers of fiberglass added on top. Then I flipped them over, removed the water-based clay parting wall, and applied a healthy dose of release agent to the resulting flange:


The process (gelcoat, plasti-paste, fiberglass) was then repeated on the second side of each hand sculpt. Once the second side had cured, bolt holes were drilled in the flanges and the parts were pried apart. The bulk of the oil-based clay was picked out with wooden sculpting tools* to prevent doing any damage to the details on the surface of the mold. To get the last residual bits of clay out, the molds were placed in front of a heater to soften the clay:


Then the surface was scrubbed with isopropyl alcohol using a chip brush with the bristles cut down to make an improvised, and totally expendable scrubber. Once the molds were free of clay, it was time to place the powermesh reinforcement. This was basically just a simplified glove:


Of course, the Genestealer's fingernails are longer than mine, so I had to snip the tips:


Then the powermesh glove was placed on the mold core:


And the mold was bolted back into place:


Once they were bolted securely, I added a bead of hot glue around the edges just in case anything might want to leak. Then the molds were ready to go:


To make my life easier, the molds were strapped to a couple of buckets to keep them upright:


Then I used a syringe and quite a bit of time to inject the molds full of Dragon Skin silicone tinted with Silc-Pig pigments:


In this case, I used equal parts red and blue with just a tiny speck of white pigment to make the plurple genestealer skin shade. The parts will get additional paint treatment before I call them finished, but they'll start with a solid plurple base color. 

The next day felt like Christmas** because I got to unwrap these beauties:


The silicone had cured in the shape of the original clay sculpt with a hollow inside in the shape of the hand armature.  The power mesh reinforcement is captured inside the cross-section of the rubber.  Platinum cure silicone like this is prone to splitting if there's even the tiniest tear, so the mesh prevents the tear from propagating through the rubber.

Removing the silicone cast gloves from the mold core turned out to be a bit of a pain, but once I'd added the claws (cast in Task 16 rubber), I could't wait to try them on:


So far so good:


The three-fingered upper hands came out great as well:




All of the claws were glued into place with Sil-Poxy silicone adhesive.  It's basically silicone glue.  Strong stuff. 

As long as I was mixing and pouring plurple silicone, I went ahead and cast a pair of knees:

While I was on a silicone pouring roll, I also poured the tail:

So now I have hands, elbows, knees, and a tail:

I've been making it a point to make the rubber parts in order of complexity.  So the first rubber pieces we made were the little flat fleshy bits to go in the forearm, bicep, and thigh windows (LINK) because they only needed simple, one-sided molds.  Then I went ahead and made the elbows which required two-part molds with a core inside.  The elbow mold was a pretty simple thing.  The tail and knee molds were basically the same.  The hands were a bit trickier, but I think I've manage to nail them.

So the next thing will be a slightly more complex mold and much bigger.  This will be the waist and hip section:

The armature is printed and layered up with epoxy and just sitting and collecting dust for a while now.  The next step will be to add the clay layer so we can sculpt out all of the skin texture.  Then I get to make the biggest mold of this project so far.

Stay tuned...

*The "wooden sculpting tools" were mostly the broken ends of popsicle sticks.
**Incidentally, it actually was Christmas day.

NOTE: when I find a product I like using and I mention it in the blog, I make it a point to add a link so you can buy it on Amazon.  This is an associates link and if you buy something using one of my links, I get a small kickback for the referral.  Even if you buy something other than the thing I link, as long as you got to Amazon from my link, I'll get a few nickels out of it.  So if you need to buy something from Amazon and you want to do me a favor, click on one of the links above (or this one LINK) and do your shopping from there.  It helps make me feel like it's worth the time invested in writing the blog.
