So, I'm hitting a bit of a brick wall. I want to get a life cast done of my head so I can make a plaster mold for mask making. However, I'd rather get it done by someone that knows what they are doing. Whether that means a professional who does this for a living or someone who doe sit as a hobby but has done it enough times and gotten good results, either or. But I can't find someone in my area that does that. I even reached out to local college art departments and they unfortunately didn't do that kind of work. I'm certainly willing to pay for the supplies and for the time. I don't know if there are some keywords I could try to search for and I just can't put it together or what. I'm in SE Wisconsin in case anyone just happens to know of any groups in the area.

I've done my fair share of face casting. The way I've always done it, we have at least a team of three. One leader, an assistant, and a mixer. Once you start, it goes very fast. I'd love to help, but I am in TN.

For my own 'HALP' issues: I've begun to seal the foam for my Fenn costume, and I'm using white plasti dip for the white parts. But I've discovered to my cost, that sharpie bleeds through white plasti dip.

Does anyone have experience with this and experience with how to avoid it happening?

Knowing nothing about that foam, would it stand up to a rattle can of killz oil based primer? Because that stuff should cover up sharpie.

Not that this will help a bunch now but I usually swipe off sharpie as much as I can with a little acetone before I paint my pieces to avoid exactly this. Would wreck your sealant though I think.

You can remove sharpie with an alcohol wipe, which is much less likely to cause associated damage than acetone. I don't know if it would do any good at this point though.

I ended up buying some rustproof oil based brush primer which seemed to do the trick. Then I tried to airbrush the base coat on and something in the way the white plasti dip interacted with the remaining open pores in the foam and a new and untried white paint just faaaaaaaaaaaaaart. Ended up looking like something with leprosy so I wiped it all off and went to primer first. Then tried again, same result.

Fortunately I had just enough white rattle can left to coat the relevant areas but thus far I have hosed up more airbrushing than I've succeeded with on this loving costume.

Me, a year ago: now, future self, you are going to have to focus on this project and work continuously probably all year to get it done.
Me, 11 months ago: does about a month's convulsive work then stops until like january
Me, a month ago: get the gently caress on with it
Me, last week: *still playing computer games*
Me, this week: just take it gently, don't be hasty, slow and steady wins the race, etc
Me, today: LEEEEEROOOOOOY JEEEEEENKIIIIIIIIINS

I think I should still be able to unfuck thisbut it's not going to be trivial.

E: update: managed to mostly unfuck it, certainly enough to consider done aside from one remaining component.

2. Use the latex mask to make a hard "positive"
3. Use the hard "positive" to design whatever you're making

Hello!

I am making a mask for my fiance.



Six-ish layers of papier mache have been laid down over a beach ball to create the core of our Emil Mask. With that complete, I've cut out holes for the mouth, nostrils, cheek dots, and eyes. The eyes could probably be a smidge closer together, in retrospect. Also, it's maybe a little TOO large? We went with an 18" beach ball whenever a 14" probably would have been fine. Still, that's...nitpicking, in my opinion.



Crayola Model Magic applied directly to the papier mache core is shaping the lips and mouth.



Next, I'll be rounding out the shape with a layer of paper clay. After that, I'll be setting some pipe insulation foam around the "neck" area (both for comfort and support), lining the mouth and other holes with black nylon fabric, lining the eyes with white nylon fabric, and building up a few other minor details. Once that's figured out, the exterior will be smoothed and painted.

We'll also be mounting an internal fan to help with ventilation as well as an internal speaker or two so that Emil's theme goes with him wherever he travels.

Updates to follow.

So I am working on a small project where I need a material that is:

1. Pourable into a mold (like plaster)
2. Becomes ridgid (like plaster)
3. Is fairly simple to work with (like plaster)
4. Is paintable (like plaster)
5. Is not brittle (not like plaster)
6. Is relatively lightweight (not like plaster)


Does anyone here have any ideas of a material that may meet those requirements? Maybe some kind of plastic or epoxy or a resin?

I use a semi-rigid urethane resin for roto-casts of masks. If what you're doing isn't huge/thick it could be a nice cost-effective material. Lightweight and paintable plastic.

The actual product I get (cause I have a store nearby) is Smooth-On Smooth-Cast 65D (white in color).

Yeah, sounds like a job for a two part resin, probably a urethane. But rotocasting something that size will be a tough thing to do.

Though, if you can work this into two parts rather than one and are willing to use something that;s a little more work, it really sounds like a job for GRP/fibre glass.

Thanks a bunch for the advice. I am going to look into both.

I did some experimenting with Smooth-On Rebound 25 platinum cure silicone. I'm amazed how simple, durable, and versatile that material is.

Also just a heads-up this is not for theatrical or cosplay stuff but I figure for this kind of thing this thread is going to be full of knowledgeable people. Plus I honestly am fascinated by some of the projects people are doing here. I'm a bit of an artist trapped in an engineer.

I would love some feedback on a thing. I've been working on a rendition of the Smart Pistol from Titanfall, and printed a model that was based off a rip of the in-game gun. I made some very precise fittings for things like switches, batteries, and other electronics, because I intend on adding lights and sounds to the thing. That said, I'm concerned it might be a bit too narrow around the rear slide. After some early assembly and holding it, it feels good in my grip, but it's just that visually it looks fairly narrow. Making the model thicker and reprinting would take ages, because it's not just a simple matter of widening the model out and reprinting. I'd have to rebuild all the inside cavities to be the right dimensions again. Still, I want to get this right...

I filmed a quick 50-second video and threw it up on Instagram to show the dimensionality, because I figured video would more accurately convey the thing over pictures.

it doesnt look thin to me. I think once you attach the slide latches and all the other junk it will fill out. Don't second guess your work, it looks great from the back.

e: on the other hand, you could 3d print a shim of a few millimeters thickness if it's really bothering you. I've shot plenty of pistols and there's not a set width for bodies of guns, and it varies wildly from model to model.

BANDAIDS DON'T FIX BULLET HOLES

That looks really good. If you want to reference with a real gun design, the smart gun is basically a 1911 with some added flair. The 1911 is also a slim gun, because it doesn't need to be thicker. Glocks and other designs have beefier slides because of the lock-up mechanisms need more space around the barrel. Also, the 1911 has a single-stack magazine (it is wide enough for a single column of bullets) while glocks and others are usually double-stack (the magazine is wide enough for two staggered columns of bullets). The trade-off is more capacity for a chunkier grip, something you don't need to worry about with your prop.

In short, your current design looks really good, and also looks to be sized about the same as the gun it is based off of. I say stick with what you've got.

I cant justify getting good boots made, but I want something more substantial to wear than rope sandals for helping a friend vend at a couple pirate/renfaires this summer. I figure it's probably just easiest to make something I can pull on over an old pair of ropers to look like knee boots.

I bought some from Amazon that look to be the same model. The charge doesn't last all night, but does last awhile. Maybe like 3-4 hours. I was most annoyed that the button to change the lights can get hit just by walking around normally. So it'll either turn on when you want them off, or change from the color you want. The design could use some work.

I was styling it yesterday, and the fibers were lovely to work with. Thankfully I'm playing "young" Pearl, whose hair isn't quite as ridiculous.

Also, since this didn't get any responses last time: I'm still looking for somewhere to buy an ENORMOUS (in terms of cap size) wig.

For Otakon, we were pressed for time and had to work with a normal girl's wig, and it looked fine in pictures, but it was bunching up and trying to escape off his head all day. No amount of bobby pins would keep it in place for more than a few minutes. So, I'm trying to find a better option. Does anyone know of a cosplay wig manufacturer that sells particularly large-circumference wigs, or of a way to modify a small wig so that it fits a larger head?

If you're looking to do it on the cheap, you can approximate something out of costuming materials using proper lacing methods, maybe plasticard or similar, or the plastic plates made to his specs, although those are more meant for SCA level heavy contact fighting than costuming. The Japanese enthusiasts of the SCA have a forum with a lot of good discussion posts on making this sort of thing.

Unless you've got a lot of dough to drop on fancier materials like real leather and thermoplastics (Worbla, Wonderflex, Terraflex, etc) I suggest you go with EVA foam. It's the stuff gym mats are made from and you can buy sheets and rolls of it in various thicknesses anywhere from the thin, brightly colored sheets Michaels and Hobby Lobby (kids section) to the industrial mats at Academy Sports and Harbor Freight. It's cheap, you can shape it with an iron/hair dryer/heat gun/stovetop, and you can layer pieces on top of each other to make ridiculously cool shapes.

First, you'll want a mannequin or dressform approximating your body shape. You can buy them or make your own out of cling wrap and tape.
http://www.keabtium.com/the-best-duct-tape-dummy-tutorial/

Also go to the dollar store and buy a bunch of cheap poster board so you can demo patterns and see how they look on your body before tracing to foam.

Here's a site full of tutorials on how to make foam armor:
http://www.hardscrabblefarm.com/costuming/index.htm

Here's a blog post that covers things like making patterns for individual pieces:
http://rydain.org/basic-armor-patterning/

I can personally vouch for this technique of strapping the armor to your body reliably:
http://www.wmarmory.com/?p=1380

I used four thicknesses of foam to make my Commander Shepard armor, and I'm in the process of redoing a few pieces for improved mobility. Also because now I (almost) know what I'm doing now.

Google results tell me to use Sintra, cut measured strips, and do a fancy weave with shoelaces. Budget is important, especially because I've never done anything like this and when I ef it up I don't want to be out too much money (gotta spend some at the Con, after all). Historical accuracy is not at all in the cards... I want to prance around in something inspired by Legend of the Five Rings at their big release party. Inspiration from this guy, but vaguely; I've no intention of trying to recreate this.



Related, if anyone is in Los Angeles and wants to help...? :haw: I'm off to Burbank Plastics tomorrow to ask about material. They advertise for industrial needs and cosplay! They know their real audience.
