After all of the tests Ive made with silicone, I came to realise that a solid silicone body just would

be too thick which would make the joints unable to bend for animation. With this in mind, I decid

body from silicone to foam, with only certain body parts being made of silicone, eg. Head, Arms,

sculpted the majority of the body in clay, and the armature was inside, this meant finding the knee j

lower legs so I could keep the clay on the feet and removing the clay from the rest of the body to g

After removing the feet and lower legs, I took photos of the body shape so I could re-create

I removed the last of the clay and cut a large square of upholstery foam, on the foam I placed a ca

previous body shape with the armature placed on top to make sure where everything wo

After I had drawn around the card, twice, making sure the back piece was drawn in reverse, I cut th

out using a scalpel.

With the two halves cut to size, with a little excess for safety, I drew around the armature, making

cut gaps to allow the alan keys to slide in so I could re-tighten any joints during anim

I cut a shallow groove where the armature drawing was so that the armature would fit snugly inside

room for unwanted movement on the inside of the foam.

After the first half was cut to shape, I cut into the second half so that the armature would fit perfec

halves when they are stuck together.

With the two halves snugly ready for the armature, I placed them together to make sure everything

I pushed some rods through the front piece, making sure they were in line to the joints that I would

I knew that heat melts this kind of foam, this is why I used metal rods that I would be able to heat. T

taking too long, so I selected another rod, held it into the end of my soldering iron so it would heat

temperature, then I would push each rod through with the hot rod to melt little holes all the way th

create access points, that way each of the rods already excising was acting as a guide for th

These images show that the holes were successful and in all of the areas I needed them. The gaps le

the screws for the alan key to get to.

Once I was happy with all of the placements of the armature and of the holes, I used some contact a

two halves together, not sticking it to the armature itself though to avoid damage. Then I weighted

would be firm and left it to set.

drew a basic body outline and started sculpting into the foam.

With a basic shape starting to take form, I used the clay arms and legs as guides to how thick I woul

leg areas. I then drew on some guides and continued sculpting.

The larger sections of foam to be removed were done so using a scalpel, but the smaller neater tri

with scissors. Image 34 shows how I would test if there was too much foam fat in the way to be a

character or if he would just bounce back to the t-pose.

This is the stage of the foam body now. I will go ahead with making the silicone body parts before

give me a better sense of scale and proportion, also, I will know better if he needs to go on a bit of

purposes with the foam interfering with the joints.
