I am aiming to build a hollow Pertwee era Auton gun hand from fibreglass.
I was wondering if any of you could use your experience to help me with the casting process.
After a look on ebay I could only turn up fists and female mannequin hands most of which were solid however I want the palm area to be hollow to accommodate the mechanism and fingers.
I don't have any moulding silicone but I do have alginate (although this Scarvia Fast Set shrinks considerably as it sets), liquid latex, plaster (I think I might bulk buy some bandages too)and fibreglass.
My budget is low so I went around searching for alternative reusable casting methods and came across the one in this video by Alex that caught my fancy although his 2-part method might not work on a bent hand.
I am thinking about coating my hand in latex to make a glove, pack it with cotton wool and then strengthen the keyed latex with plaster but would I still need to cut a seam into the latex to remove the slush casting?
Or could I remove the plaster mould casings then just peel away the latex, as if it were a glove?
The hand: straight fingers with a grips-all action man thumb.
Thank you for reading my wafflings.
