Making a Simple Silicone Mold for Epoxy or Urethane Casting at Home

In this video, I am making a silicone mold for epoxy casting. The mold that I am making will make a custom screwdriver handle which can then be put on anything that you might want a screwdriver handle on! The silicone that I am using is Smooth-On Mold Star 15 Slow. This is a relatively bubble free silicone. To be even more sure that the silicone mold will not get bubbles, I ran the uncured silicone in a small vacuum chamber.

Can I use a polyurethane part to make the mold? I have electric longboard sleeves that I'd like to start making at home instead of ordering from China

That was some cool stuff that I liked. I am a guy. Well done.
