dorg, great stuff man. scout casts are looking great.
you be able to give me a quick how to on the best way to make a mold of a head with no neck? gona make casts of my jango/ clone head and not sure how to go about it. appreciate any hlep when you get the chance.
I dunno what Dorgs's solution to that is, but what I do is I make a clay "neck" by sticking a lump of clay under the head if it has no neck, then you pour the mold. When you remove the clay you can either:
A) use mold release (professional stuff, or just vegetable oil or vaseline) and make a second part of the mold that fills where the clay neck used to be
or
B) don't make a second part of the mold, just when you cast it, if you're casting it solid (not recommended) don't fill it all the way up, or, if you're rotocasting (spinning the mold while the resin sets so it makes a coating over the inside surfaces of the mold, which makes the cast end up being hollow and more bubble-free), then you just rotocast it and dremel off the extra neck part.
I hope that answers your question... If you mean how do you set up a mold around a head without a neck, well instead of sticking the head straight into your poured mold upside down, you put it on a blob of clay, right side up (not upside down) inside your mold container.
I'll post diagrams soon if you'd like.
EDIT: Here's a diagram I whipped up, hope it helps!

1- just the headsculpt before casting
2- the blue area represents a blob of clay stuck underneath the head to provide support
3- the mold box is constructed, represented by white lines
4- the silicone is poured over the head in the mold box, the silicone is shown as pink
5- After the mold has cured, the mold box is deconstructed, leaving only the mold itself with head and clay inside
6- The mold is turned upside down, and the clay is removed (scraped out)
7- The opening of the mold is widened with a knife, creating a funnel shape. Some form of mold release, i.e. vaseline or vegetable oil, is applied to the silicone to prevent the second part from bonding with the first part of the mold
8- The second part of the mold is poured, represented by a lighter pink than the rest of the pink silicone
9- Once the second part cures, it is removed
10- the original head is now removed
11- Resin is mixed and poured into the mold, represented by a light yellow color
12- the mold is not all the way full, and the second piece is put back
13- the mold is rotated by hand while it sets, covering the inside with a thin layer of resin.
14- here, the resin has finished curing, with the light-yellow cast head still inside the mold
15- the second piece of the mold is removed
16- The cast head is removed from the mold. It is shown side-by-side with the original. You now have a hollow replica of the original.
