    Frank Ippolito joins us at Adam's shop for another step-by-step tutorial in prop making. This time, we learn how to make a two-part silicone mold that we can use to cast resin copies of complex objects. We demonstrate the technique by duplicating a lightsaber prop made by Adam!

    Here is a better way to judge how much silicone you use.
    Weigh your clay. Before you start know how much clay you have. Clay up your part. Subtract your leftover clay from your start weight. This will tell you how much silicone you're going to need. (roughly). For the second half. if you weighed your part. Weigh your mold and part. Subtract your parts weight, and thats how much you need. Or weight the clay you took out if you didnt leave a cavity under it...

    Registration points are important but you don't really need this many. Now, that shouldnt be confused with a ridge or edge. Ty pically youll use a registration every inch or two, but a small ridge all the way around is important if you don't have a lot of waste silicone on the sides. When there is not a lot of waste silicone on the sides you may get bleed out of resin. With a cut ridge all the way around, your resin is less likely to bleed out.
    Why does any of this matter? Sometimes your mounting piece is not clay. sometimes you mount something to a board or something hard. And you'll need to glue down registrations.
    The wavy line typically is more for bleed out than for registration.
    Smoothon is very susceptible to inhibition, (I didnt bother looking to see if mold star is plat or tin which determines the susceptibility) so the krylon helps to seal the clay and part in case it has sulfur in it. I typically use Alumilite or Polytek as their silicones seem to be more resistant to inhibition.
    The only real critique here is the amount of silicone they used.

    That was fascinating. One thing I especially appreciate with the questions that simplified things especially for people like me to help understand the process and what's need to achieve the end result. I've never used resin before, cause I never thought it would be available or easy to use since I've tried making arts and crafts the harder way. After watching this video, the ideas and possibilities are pouring in so fast to the point where I'm getting a head ache. Now, it feels like that all things, art and crafts feels possible and endless.
