I made this at TechShop Menlo Park. http://www.techshop.com

I
 made many wax chicken feet and head trees because I wanted to make replicas in aluminum using the lost wax technique. I was planing on cutting them off the sprues (branches) and end up with metal chicken parts but they turned out so cool that I left them intact as weird freestanding aluminum sculptures in the end.

Step 1: Choosing Wax

I choose to play with beeswax and hard microcristalline, the paraffin wax I had at hand was way too soft but in it's hard state I think it would work. Mixing waxes is also possible I found.

Step 2: Melting Wax

In a double boiler melting wax is quick and easy. Liquid state is achieved without the wax smoking which means: Too Hot!

Step 3: Casting of the Parts

I poured hot wax into pre-made silicone molds of real chicken feet and a chicken head. In a few minutes they harden and you can take them out, allowing more wax to be poured in to make many replicas.

Step 4: Making a Base

I used a small cup and made a hole in the bottom to stick the main sprue into. I'm using a premade red french wax sprue which serves as a channel for molten metal to get to the object once the wax is burnt out of the mold. I filled the remainder of the cup with soft paraffin doe weight.

Step 5: Making Small Sprues and Attaching the Feet to the Base

Smaller sprues had to be cut to size and attached to the chicken feet. I used a soldering gun to heat the ends of the sprues and attach one end to the objects cast (the feet) and the other to the main sprue.

Step 6: Creating a Tree

Continuing to attach sprued wax chicken parts to the main sprue base a very weird tree started to emerge. These trees are now ready to be submerged in a plaster mold, burnt out and cast in aluminum! 
I had so much fun doing this. I highly suggest it! You can make a sprue tree with any object if chicken parts don't excite you as they do me. :)
Do you have any tips for making wax copies of things like how you did with the chicken feet? I want to cast my daughter's pulled tooth and need to make a copy of it. What's the silicon stuff you use? <br>TIA!
Very creative and an interesting object. You have good hands and work the material well ! Do you have any pictures of the (final) aluminum castings?
Creepy but wonderful!
