This weekend is a bank holiday here in the UK and as always that means it's time for some serious work to get done! And that means puppets! I've taken the plunge, I've made the leap, Clara is finally underway!
Come on, I'll show you. Maybe I'll learn something :)

The lower face has been removed, and will be moulded as a separate piece, allowing for replacement animation to take place. For those of you who are unaware, replacement mouths are used extensively in stop motion animation, to facilitate a characters lip-sync, or talking, with a minimum of fuss. Essentially, the puppet's head is one large piece that remains the same for each frame, whereas the bottom area of the face is replaced in each frame with a different mouth shape.... an ooh mouth here, an aaaah mouth shape there; a smile, a frown, whatever.
I set about making a two-part mould of this head piece in much the same way that I did before. Learning from my initial go, I decided upon a more intricate seam line that would allow for easier removal of the piece and ensure no undercuts.
To both test the mould and begin production on the lower half of the face, I decided to take a casting of the mould with a much lighter plaster (as it was the only thing I had to hand) so that I could have a hard positive of the head, against which I could sculpt the lower face.
The first casting didn't go well. While the mould was nicely lubricated and removal of the plaster piece was fairly easy, the hole through which I filled the mould conjested and fooled me into thinking the mould was full when it was still half empty.
AGAIN!
The second casting suffered the same issue, and although her nose was lost in the removal process, I did end up with a usable cavity on which to sculpt the lower face.
You can see her that I have left of any mouth details, as this blank face piece will be moulded and cast again and again in plasticine, on which I will sculpt the individual mouth shapes.

A word of warning, sculpey will float in plaster if you do not glue it to the bottom of your mould box. I found out the hard way :)
A couple of quick casts later and I had something approaching completion, of the moulding process anyhow.
The final pieces will be cast in newplast plasticine and theres a lot more work to be done in designing and sculpting mouth shapes, but hey, we're building puppets and we're underway!!!
Thanks for dropping by
Josh.
