Re: Tutorials? sorry, I know this question might get a bit old...


WOW, I love these threads, get to see everyone's different take on things.

Blackbat, as far as I'm concerned, a box mold is just that, a box is made around the item, silicone is poured into it, let cure, and that's it. Like what drgnfyre did with evilgenius' batarang. Anything above and beyond that would be a support shell, jacket mold, etc.

As far as wall's it's generally at the widest place, but you have to watch for undercuts and adjust slightly from time to time. If you look at the pictures in this thread (]azbat costume), you can see the seam running up the sides of the head.

Also, as a general tip for walls, you want them to be as smooth as possible, completely perpendicular to the sculpture, and flat where they meet the sculpture. This cuts down on seam clean up dramatically.

Any time you spend on the mold will save twice as much time when it comes to cleaning up the casting. You can also see where the dividing walls were in the pictures here (]click here).

You can probably find more information here at
]monster lab since mask making/cowls are primarily the same.


Pat- go here, ]links to FX supplies and more. I broke it down in sections, LOTS of links, not all specifically bat/cowl related, but supplies for FX in general.

As for cores and foam latex, foam does shrink, quite a bit in thicker sections. I've never seen or personally heard of anyone using a core in a slip/slush casting process for a mask with the exception of a friend adding a part so he could make the back of the mouth solid, but it was small and didn't seal the mold.

If you were going to cast a solid cowl in urethane, silicone, or foam latex, then it'd be the way to go to have it form fitting and move with the wearers face as much as possible. If you were going to do that with a cowl, for anyone interested, I would make 3 registration points, the eyes and a thin wall just inside the mouth area.

In other words when it comes time to mold the sculpture you would leave those stone to stone (or whatever the mold is made of) I can add more in that's confusing anyone.

Already lots of great info in this thread, so I'll shut up for now.

Tom

Thanks for the links bro. :)

Or, you know what I just realized Tom? I'm just a few miles away from FX Supply([sign in to see URL]) here in Utah. I remembered you mentioning them in another thread. I could probably get most of what I need from them.

Come to think of it, one of my coworkers has connections to that place, a friend of his dad made him a latex prosthetic for last halloween. So if I want a lifecast(which I will), I'll have him hook me up.

I didn't realize how close to home some of my supplies probably already are. :)

So... What are "undercuts"?

And do you have to make a wall for each half of the mold?

Undercuts are places where the sculpt would make an angle under itself that might be hard to remove from your mold. For example, if you were to sculpt a mask where the nose hooks downward at the tip and the underside goes back upward, this is an undercut.

As for the [sign in to see URL]'s only one, and it goes across the sculpt from side to side. For example, if you were sculpting a mask, it would start at one shoulder (like the right side), go up the right side of the neck, up the right side of the head, across the top of the head, down the left side of the head, down left side of the neck, and end at the left side of the shoulder, just like in those pics on the page I linked earlier.

On a bat-cowl, would that wall be routed over the top of the ears or behind or in front of the ears? It seems like it would be tough to build a wall right over the top of thin, sculpted protrusions like that.

like the song says..."pimpin ain't easy but it sho is fun" emoticon

never having made a cowl, but lots of odd things, I'd say best bet would be to stick with going over the ears, especially if you're doing a long ear. trying to clean clay out of tight spots like that can drive you :cookoo quickly.

If you sculpt in a firmer oil, wax based clay you might be able to put some water based behind the head and lay it back, then stuff some support underneath the clay to help. like this (but on the back so you don't mess up the more detailed front half)

then make your wall in clay like so

Pat, see, ask and you'll find something in your own backyard. if you do happen to go out there I need some MSDS and tech info for the files on the breakaway bottle blend, they've been a little slow on getting some out here.

I likely wouldn't be doing this for a couple months, but if youre still in need of these things by the time I go out there I'll check on them for you.

great, thanks Pat.

Also, the mold walls there have a gutter cut into them, you don't need that for masks/cowls. I made a urethane mold off of that and use those in urethane and silicone. If you use them on stone molds they may lock together.
