  • Reusable do-it-yourself molds

    Hey all,

    I'm trying to figure out the best way to create parts for a room in my maze.
    I'm building a giant birds nest out of bones, skulls, misc. body parts..
    My plan is to use spray foam for the actual pieces and I thought that I could use the same parts over and
    over again but I'm struggling with what to make the molds out of...

    Any suggestions??????

    Spray foam doesn't really work well in a mold. it air dries and molds tend to seal the foam. vacufom would be good, or latex bones from a plaster mold (very easy to make a plaster plate mold).

      your best bet is a silicone brush up mold with a fiberglass jacket. Forget spray foam, try a 5 to 8 lb two part rigid polyurethane foam check out Smooth-on they have all the materials and how to videos!
      I won't just scare you...
      I'll F#@% you up for life!

        Hardware store silicone

        I watched your U-Tube video on silicone mold...
        How well will that hold up??

        Do you think I could get 5 or 6 plaster heads out of a hardware store silicone mold??

        Also, thanks for all the info, man.. My plan is to build this entire thing myself & your tricks & ideas have been fantastic resources.

          the silicone molds hold up great, i hink I did 10 pulls, but remember mine was open backed.

            Silicone

            Doesn't seem like it would be impossible to do 2 halves...
            I'm going to try something similar to yours and get the hang of it then I'll try a skull...

            That real stuff is $$$$$$
