Question

Making and casting mold from stuff in your house.... Help! I'm trying to cast a mold of a propeller because one of the broke on my rc plane.

Answer 1

There are lots of things that will make molds from materials you can find around the house or buy cheaply.

Check out this page at my site for all kinds of materials, from polymer clay to glues, etc., to more conventional molding materials:

(if you'll have "undercuts" in your mold, you'll need a mold material that sets or dries flexible)

Answer 2

You'll need something to take the mold. Alginate works well. It's a cold setting gel-like formula. You pour it over the object you want to make a mold of. You layer it with plaster strips and let dry (Actually, it'll warm up, and cool again. Then it's time to remove the alginate).


Once you remove it, you fill it with your material of choice

Let dry overnight.


Remove


Viola, you have a mold. A positive and a negative.
