Creating a Hard Helmet


:help I've looked through the archives for hours and hours and I can't find anything that seems to answer my questions.

Okay, so I'm taking a whack at making an Iron Man helmet, and I've never done anything like this before. I've got as far as making a plaster mold of my head, but I don't really know the best ways to proceed. My understanding so far is that I need to sculpt the helmet in clay (Super sculpty?).

First question: Is there a "best clay" for a project like this? Has anyone ever heard of Permoplast? I have a bunch of old permoplast oil based clay and it's pretty firm, but I don't know if it's just because it's old or if it is supposed to be like that.

Second Question: There's a lot of info here about resin and latex, but does anyone have any advice for molding this in plastic?

I've been told to just get a certain type of liquid plastic that will form to the inside of the final cast as I swirl it around then harden, but that sounds a little iffy. Any advice?

I didn't really know what section to put this in. Thanks for any advice Bros!

I'd recommend going over to the dented helmet forum to look at how a few of those guys are vacume forming plastic. That might help you along a little more.

Firstly I'd suggest a chavant clay. I like NSP medium. You warm it up a little and its easy to work with and then it'll harden just a little for the finer details and such.

Next, as far as molding, theres a fairly basic rule that you want a hard (fiberglass/stone) mold for soft casts and a soft (Silicone) mold for hard casts. For a helmet your going to want to make the mold in silicone.

And as far as the final cast, I'd suggest fiberglass. The plastic method your speaking of (I believe) is referred to as roto-casting and can be difficult if you don't have an apparatus to do the spinning for you.

Sounds like excellent advice so far. Thanks.

Archytextural, what is the dented helmet forum you speak of?

NewBat, do you know why silicone molds are used for hard casts? Thanks, I think the archives might be able to get me through the next few steps.

If anyone else has any advice for a first timer I'd really appreciate it all.

You want a hard mold of soft casts so that the casts can flex and pull away from the mold and you want a soft mold for hard casts so that the mold will flex away from the final piece.

And you might want to try it on a smaller scale. Maybe pick up one a mini-head and sculpt on that...just to get a feel. Monstermakers.com has one. And people like Chavant. I use Kleen Klay on what little I've done. Pick up a bit and see if you like what you're doing first. Don't go out and blow a small fortune on 50 lbs of clay and figure out you don't want to put up with the bother.

Sorry, I assumed you hadn't done anything before.

Good assumption, I've never done anything before. Thank you for the clarifications guys. I'll be sure to include some pictures when I've made a little more progress. BTW, I looked around at a few art stores for "chavant" clay, but I couldn't find it. Is this an online kind of purchase?
Thanks again brothers!

Monstermaker.com sells Chavant clay, I think it's $6-7 for 2 lbs. I also like the NSP medium, it's nice to work with. Monstermaker pretty much sells everything you need for sculpting, moldmaking, etc. Good luck!
