Is resin an option for the mold you have ? I would be happy to purchase a resin copy to help fund your project if possible.
Sorry, It's an ultracal 30 mold, which I'm pretty sure is limited to Silicone and latex, and I've heard bad things about casting the two materials in the same mold, so I'm limited to silicone.Is resin an option for the mold you have ?

I want to make the resin skull, but I don't have enough money so I'm waiting on that.
Huh, that's actually not a bad idea. Water based or oil based clay?You can get resin and fiberglass for relatively cheap at Home Depot. I made the fiberglass skull for my raptor by lining the inside of the mold with a very thin layer of clay and fiberglassing over the clay. Then just cast a latex or silicone skin and it should slide on the form and fit perfectly.

EDIT: Actually, I'll probably end up lining the inside with a few layers of aluminum foil topped with wax paper and making tape instead of clay, so I don't have the headache of mold cleanup again.

Hi.
if you need some funding to finish your work, I Have a customer in the UK who will buy one off these heads in silicone from you :eek
He is building a wrangler jeep replica from JP1 and I made the light bar & custom lights for him.
he would love to have a raptor head to go with it..!!
if this will help you out let me know by PM and i can show him you Raptor Head.
Also I would not Do lot's of casting in your mould until you have casted a master copy
This is Important to protect from future damage.
Chow.
I do want to make a master copy as soon as possible, since I can see a few more air bubbles popping up after my two casts. What materials would you recommend to cast in for a master copy?Hi.

Would the plaster not bond to the Ultracal 30 I used to make the mold?Kinglee's advice is sound.
The first thing i tend to do now is make a plaster version, when my mould is ready. this is the master copy, so if the mould gets damaged, you can make a new mould from that.
Treatment of the mould and master for release and protection, varies depending on the materials used
I tend to use fine casting plaster which provides great fine detail and hardness. You also get a 25kg bag for less than £10 ($15) .
The masters also look cool on a display shelf
The clear coat was to make it easier to release from the mold.Wow, the texture is really good. Can I ask why you decided to clear coat it? Was it just to protect it while you molded it?
This is how a jaw mech could work from inside the raptor body.

You have a string , a pivot point, and a spring.
You pull the string, and the mouth moves open on the pivot point. The spring returns the mouth to it's closed position when you stop pulling.
Great sculpt, and pull of the JP Raptor head!
I'm actually from Stow, too. I just go to Kent for school.Awesome work man! Looks like it is coming together nicely!
BTW, I just saw you're from Kent. I'm from down the road in Stow. Just thought that's kinda neat.
Well my next major step was to create a foam core, nothing too exciting. Now I need to order more silicone to repair the seamline.Oh I see, they are showing the one in the same mechanism with two components, for second there I thought they were two mutually exclusive solutions to the jaw mechanism, thanks.
The cast is looking killer, whats the next major step you need to undertake?
