Taking off from this BRILLIANT 'ible http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ I have started making silicone molds on the cheap and thought I would share. This is incredibly simple and fast and can be used for a ton of casting ideas...
Here is the podcast I did on it:
The basic instructions are below....
Step 1: Materials
You will need:
- SIlicone Calking (the stuff that stinks like vinegar or acetic acid) I have a calking gun but you can get smaller tubes of it at the hardware store
- Mineral Spirits (this is just paint thinner but somewhat less toxic than the rest. NOTE: you can use white gas or camp stove fuel but be CAREFUL if you do use that. The advantage of white gas is that it will cure the mold faster and the mold will not smell like mineral spirits after)
- Corn Starch
- Latex gloves (or what ever kind you like)
- mixing sticks
- Bent nail
- Something to cast or mold
- Small box
- Mixing cups
- Wax paper
- Play dough
Step 2: Prep the item to mold
- To prep the item for the mold cover it with Vaseline (if it is a bit goopey use a blow dryer to melt the Vaseline and smooth things out).
- Next cut the bottom of the box out and place it on a piece of wax paper
- Get some play dough and fill the bottom of the box with a layer thick enough to cover half the figurine (don't put the figurine in yet this is just setting up the base
- Press the figurine into the dough and make sure to cover 1/2 of the figure
- Vaseline the dough and the figure (if it is a bit goopey use a blow dryer to melt the Vaseline and smooth things out).
