Armature Build

So I  have finally got around to the building and making section of my film. To start off I decided I would make the armature for my main character Ted. He will be the only animatable stop motion puppet in the film and the rest will be 2D characters.

To start off I printed out the plans for my character to scale so as i could cut and measure the components needed to the right size.

The armature was made using K&S Brass tubing, Circular tubing and twisted aluminum wire

I began by measuring the the tubing against my model sheet plans. The tubing is used to help create joints over the twisted wire by stopping legs and arms and chest bending where they wouldn't on a real person allowing room for movement at the knees, elbows,waist, shoulders, neck etc.....

I then cut all the tubing to scale

I filed all the tubing edges so they could slot together easily where needed and to blunt them slightly so as the would not scratch or cut the wire which would weaken it for animating 

This picture shows the tubing cut and placed on top of the plans to make sure they are the right size

I used two sizes of K&S tubing which could then be slotted into each other. I done this so that every limb was replaceable incase they broke or were damaged during animation. If that happened I could then replace the limb rather then having to build a whole new armature.

Aluminum wire was used to allow the armature the ability to move

Strands of wire were twisted together to allow movement while also giving it strength for animating. I done this by holding wire in a vice and twisting it using a drill to get clean smooth twist.

I measured the wire as I did with my tubing and cut it to size

I covered the wire in a shrink wrap tubing to give extra strength and help prevent wire getting scratched and worn

I used a two part epoxy resin to glue my armature together

Here is my was joints and rigging points glued together
