    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!

    Can we pour concrete in the molds or do we have to use different silicone?

    Tips, you didn’t keep the silicon in the vacuum chamber for long enough and if you don’t want bubbles in the resin once you’ve cast it then put the mould into the vacuum chamber for 2 minutes with it running, give it a top up with more resin if needed and 2 more minutes in the chamber and it’ll be perfect! Happy casting

    if you want to calculate the volume of the object you're casting, you can fill a tub with liquid and submerge the item into the liquid and measure how much the water level increases. the difference is the volume.

    Pressure curing the silicone after the pour is (in my opinion) a better method. I use Moldstar 20T and with a 6 minute pot life, running to the degas chamber takes away precious time from a low viscosity pour. Pour your mold and then place it in the pressure tank. The pressure evacuates any air bubbles while the silicone cures. I realize that in this case, the lightsaber may be too large to fit into a pressure tank but this may be a useful tip for molding smaller items.

    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...
