Stone Torso Mold


I searched through the archives for anything about this, I apologize if I missed anything.
 
I'm working on a Begins chest and back piece that I'll be casting in latex but I've never molded anything larger than a full bust.

I'm wondering if it's the same approach as masking a two piece mold of say a cowl?

I was hoping to dwell cast, but I'm thinking this would be one heavy beast to have to drain when it's full of latex and probably still too heavy to have to keep rotating around to slush cast.

Is there any other method that you pros use?

I'm aware of fiberglass, silicone molds for urethane and whatnot, but I have to stick to latex right now.

Like you said, you can roto it with force (watch your back when lifting), or do brush up layers.
 To make the mold easier for slush casting it, take your time making the mold itself. use PVC pipes for the support and burlap as well. It wont be as heavy as you think it will be if you take care in doing lighter layers that are more reinforced, rather than a huge stone civil war wall mold.

Fiberglass, silicone and urethane molds can be used for latex as well. It just takes much longer to get a finished piece. If your going to use plaster and you make it thin, it loses the advantage of being able to suck the water out of the latex so you have a heavy mold that isn't very absorbant, which is the whole reason for using plaster in the first place. It will be more absorbant than the other materials but you will still have to paint it in in layers and dry it for a few days.

If you do make a thick mold that its fully sealed you could pour in the latex and let it dwell you could have a finished piece in about a day. But it will take alot of latex( probably 15-20 gallons) to fill that volume and will be very heavy, and difficult to work with.

Thanks guys, I'm thinking about brushing or slushing layers in each of the mold halves separately then joining the two mold pieces together before the latex cures. Hopefully I'll be able to fill in the seams and have the torso in once piece.
