I use the build up method. What I would do is making the skull from a 2 part epoxy putty (eg Milliput, which is what I use). and then build it up with latex.
Hi, I would not use 2 part epoxy because of the weight-it's really heavy...at least not for the structure-maybe a thin layer to look like bone...BUT, I would first make the shape of the frill as a cardboard cut-out; cardboard like the heavy gray kind on the back page of a pad of paper...you know, like yellow line paper that tears off at the top. So cut out your shape-bend it a bit so it's not like a straight flat thing-it should bend back from the face area and then up a bit-then you could use some epoxy putty or better yet; some Celluclay (it's a powdered paper mache that you mix with water and wood glue)-this will stick to the cardboard great and dry with a really cool oraganic texture like bumpy bone...I used this technique for the crab monster in Sinbads 5th Voyage. Hope this helps!, best, Stan
When I did a Chasmosaurus, I sculpted the head in plasticine, made a plaster mould, then cast it in foam latex. Inside, there was a profile of the skull and beak cut out of 6mm ply, with a loop of wire running around near the outside edge of the frill. Armature wire also attached the jaw piece.
If you aren't going to get into the moulding and casting, probably go with something similar to what Stan is saying. If you have trouble making the complex curve shape of the frill with card, you could still make up a shape in plasticine to build the shape over. I would probably start with a layer of liquid epoxy resin over the clay, with woven fibreglass cloth, to get a thin but strong shell. Then build up in putty or Celluclay over that to get the texture. Once it is set, you lift it off the plasticine.
I used a technique similar to Stan's for a Monoclonius puppet. I drew the general shape of the frill on a piece of thin cardboard. (A old cereal box would probably suffice). I then cut the shape out with pinking shears to give the edges a serrated look. This was bent to shape and coated with a 50/50 mixture of water and white glue. While drying, I stuck on a thin piece of medical gauze on each side of the frill. After drying, I trimmed the gauze with pinking shears to match the serrated edge of the cardboard. I attached this to the model with rubber cement. After the rubber cement dried, a coat of liquid latex was applied to gauze to form skin and to further secure the frill to the neck. Here is a pic:
Stan, any chance you could post a photo of your creation ? Thanks.
Hi Steven, I don't think I can -sort of in the same boat as Ron, and the cyclops which he wants to share more pictures of...but we're under a "NDA" (non disclosure agreement). We can only refer you to the officially released photos from the film...The new trailer has a quick shot of the crab and cyclops battling...and from the same sequence a still shot of the crab is on the "Sinbad the Fifth Voyage" facebook page. When we are allowed to we'll be posting more pics and behind the scenes stuff...
Nice! Sweet Ron- I'm giggling right now!
@ Dan - you forgot the UUUUMMMMMMMmmmmmmmm!
It's just not as powerful without the UUUUMMMMMMMmmmmmmmm!
There goes the box office, now that we've seen this detail photo there's no need to watch the whole movie!
That "sandy claws" texture looks great in a big closeup! Some really nice details there, like the sharpened edge, and the little teeth on the lower mandible (or whatever you call half a claw).
How would you secure the skull structure to the wire body so it will hold effectively ?
