I have a question as well regarding this topic as well, sorry Zep...
I guess we will bot have to wait for an answer.

Can you pull helmet parts ie. shell with a 5 HP shop vac, or will you need a high vac system?

I havent made my own helmet before, but as far as sculpting it, thats pretty hard in itself to make sure both sides are symetrical and looks good. Ive seen trooper helmet molds made from MDF, but the face plate was made in several sections, rather then one whole solid chunk of MDF. I guess you have better control that way, because for instance, you have the "eye" section of the helmet. You start on the left eye, from the outside of the helmet, to half way through the bridge of the nose, and from where the top of the face plate, to just above the "mouth". You can accuratly measure and sculpt that one section, and just reverse the measurements for the right side eye. You would use this method for the rest of the face plate.

Another way of sculpting the helmet, is to sculpt it from clay, and make a plaster mold of that, and form a solid plaster cast from that mold.

Pulling a face plate I imagine can be difficult, just because of the dips and details you need to produce. However, if your using HIPS, you shouldnt have too much trouble so long as you have vasaline, or I use baby powder as the releasing agent.

From what I learned, you will only really need a high vac system if your using ABS just because of how difficult it is to work with.

Hope this helped.

90% of a costume is in the face, and the stormtrooper helmet is no exception. Gotta get that right, or the whole costume suffers.

There have been several makers make their own from clay. Master Replicas makes one that is a 3D laser scan of an original. Andrew Ainsworth, the original maker of the trooper helmets for Lucas back in 1975 also sells them. Many of the 501st use a helmet called a TE, ABS-80, and others cast from an original helmet.

I've been working on a new helmet sculpt but yet to have a useable mold. Dome and back, ears, and the face is all that were used originally.

Recasting is a big no-no in the replica prop communities, regardless of origins, so filling a kit with plaster and forming that is not considered a good thing, and will get you black listed among the replica prop/costume circles unless you own the original prop or have permission from the original prop owner.

Could you clarify that part about owning the original prop?

Do you mean that if you own a movie prop or a purchased replica, it's okay to make a copy or two for your own use? (A "fair use" kind of thing, like backup copies.)

Or do you mean that if you own the original movie prop---not a replica---it's okay to recast it and make a fair number of copies to give away and maybe sell, so long as it's not enough money involved that Lucasfilm's lawyers come after you?

It's my understanding that Lucasfilm tacitly approves of small-volume high-quality replica sales, because it promotes the Star Wars fan culture without costing them much---but if you went into mass production, they'd be all over you.

I'm not a huge Star Wars fan myself, but I'm curious about the culture. (Don't get me wrong, I really liked the first 2 1/2 movies... I'm just not into the all-out fandom thing, about anything.)

I'm curious about the proprietary attitude towards molds and things.

Being from a free software and open-source hardware background myself, I'd sort of expect that committed fans would start giving away their sculpts---saying PLEASE copy my shapes and make more, as long as you keep the quality up, and preferably produce more stuff for others to use freely.

That way, armormakers could share libraries of shapes, and everybody wouldn't have to sculpt the whole thing. If a few people did some very good arms, and a few people did some very good legs, and a few people did very good breastplates, and so on... then everybody could have 3 or 4 versions of every part, to assemble suits that REALLY FIT almost everybody---at least, to the extent that S-M-L-XL clothing "fits" most people.

There are several versions of that idea that people apply to software libraries, books, circuit designs, various machine designs, etc. One is just to declare things public domain. Another is to impose restrictions like not-for-profit reproduction, where anybody can play. Another is just cross-licensing---you can copy my shapes if I can copy yours---among a limited number of players.

I'm kind of surprised that stormtrooper armor hasn't gone that way, and wondering why not.

A very few people with a scanner or a CNC machine could save a lot of people a lot of work, and get better results.

I'm guessing that one obstacle is that for a lot of armor makers, there's a desire to do the whole thing, single-handed, and show off a tour de force. Or maybe there's a concern that if there's clearly an organized consipiracy to make it easier to make the stuff, the lawyers will crack down...?

Doing it the other way seems cooler, though. There are simple techniques you could use to come up with useful variants of other people's armor, like a "stretch" version for short tall people. (Run the casting through a bandsaw to slice it thin, then stack it up again minus the kerfs to make a "short" version, or put little spacers between the layers, and fill in with Bondo to make a long version. You'd still have finishing work to do, but you'd capture the modified shape pretty accurately.)

For people who are somewhat proprietary about their molds, there are weak versions of this that might be useful. For example, you could let somebody recast your stuff, but ONLY to make a shorter or longer version. They couldn't sell the original shape, only their variant, and only if they give you rights to their modifications so you can sell those too, and fill out your product line.

Has anybody heard of people doing any of this stuff?

Wow, Paul thats a tough one.

Take as an example: Let's say you made a piece of art, all unique and original. People loved it, and you were asked to make copies of it for sale. All within your rights. You sell a few of the copies, and a few months later, you see someone selling copies of your art on ebay! You don't get any recognition, or compensation. You are P.Oed.!

Thats the rub with recasting. It gets to be more of an issue when dealing with popular icons like Star Wars.

Over on www.theRPF.com sort of the grand-daddy of replica prop groups, the code of conduct in this 'gray marke't is this: if you own the original, screen used prop, you are allowed to make replicas of it. If you buy a replica, and make a copy of that, and do so without permission from the original artist/ owner, then this is considered 'recasting' and is considered unethical, and by some, stealing.

So, one may ask, what is the difference, recasting an original, and recasting a copy? Well, it has to to with ethics. Take the trooper helmet. TE, aka Trooper Expert, who bought an original screen used Star Wars stormtrooper helmet. Paying more than the cost of a new car for it. He then spent time and effort making molds. He then vac formed it, and made replicas that he sold. These were very limited in availability, and were of top quality. About as close to the screen used one as you would likley get. Later on, TE even spent the cost of a house to buy a full, screen used set of armor! And did the same thing. He made molds, and sold copies.

All, ok, to the replica prop communitity. TE had an original, so he was ok to make copies. George Lucas and his lawyers might have a different opinion, but thats not who we are talking about here.

Now someone comes along, and buys one of TE's helmets. He then makes a copy of it. Then sells them on ebay for about 1/2 TE's asking price. This 'recaster' is out for a quick buck. Did not incur much in the way of expense, and did not have permission from TE to make copies. Each helmet sold was one less that TE might have.

Wait, it gets better...

Star Wars props were, many times, made from scrap, and bits of junk left over from once commonly availalbe parts.

An example, the Stormtrooper blaster is a British L2A3 Sterling 9mm machine gun with a WWII US Tank spotting scope, a German analog machine counter, and some rubber strips added. I bought all these real-world parts, spending considerable time and money tracking them down. I have made molds from these parts. I sell these from time to time on this site. I take offense when I sell a kit to someone, and a few months later, find that same person selling recasts of my kits. This unfortunately is part of this hobby, and happens from time to time. That $50 kit, cost me a $1200 to make! The recaster, cost him the $50 kit, some silicone and some resin. I'd have a pretty low opinion of him. After all, I own the original parts! Even though these were not ones used on screen, they are however the exact same type of parts as the ones used on screen.

No fair use, no open source agreements., that I know of.

Lucas owns the rights to all things Star Wars related, and cracks down from time to time on blatant violators. In many cases, no licensed version has ever been offerred. The costume community is a recent phenomenon. And the Lucas Machine allows these small time, cottage industires to survive, just as long as it does not cut too deeply into his profits!

Technology has a lot to do with it. Also, there is a weird 'honor-among-theives' at play here as well.

If someone were to make G-code CNC CAD files of these things, and all you needed were a home- CNC mill, it might be a tad different.

An example of this is the open source G-code for making your own M1911 or AR15 receivers. Israel Franco's CAD drawings of the trooper armor are the only ones I know of, and these are for reference use only.

Ethics.
