Air Bubble Holes15300 viewsThis is what happens when you forget to put vent flutes in your mold. Air gets trapped in corners creating a hole in the item being made.

Fresh from the mold15233 viewsThis is what the part looks like fresh from the mold. Since I lost my mold keys there is a little leakage around where the two parts of the mold join. The extra plastic is easily removed though - no big deal.

Cutting the excess in the filling hole.15401 viewsI always use a funnel type filling hole, as it makes it easier to fill the mold. Unfortunately this also makes a solid tab that keeps the mold shut when the plastic hardens. So here I am cutting the tab off so I can open the mold.

Pouring the plastic15287 viewsHere I am pouring one part A of the resin plastic. I'm using Smooth-Cast 300 from Smooth-On. I prefer the 300 series because its very easy to mix - 1:1 ratio by volume. It only takes 30-60 seconds of mixing, and starts setting up within 3 minutes. 10 minutes after pouring, you have a part! Its a fairly sturdy plastic, yet flexible enough that it doesn't shatter/break from an impact hit.

After measuring15165 viewsAfter measuring I pour the two parts into a non-wax paper cup. This stuff will pretty much stick to and eventually destroy most containers. Paper cups make a great mixing container that you can just throw away when you are done. I do the same when making the mold.

Stiring the gel.15256 viewsPicture Cathie took of me when I was mixing the mold gel. (bad Cathie!- my hair is a mess!) This is the hardes part of mixing the mold silicon. You have to mix consistantly for 3 minutes - brother - your hands will let you know that is a LONG time to mix by hand! I'm using a paper cup and a wooden paint mixer since both will be coated with the silicon and not be good for anything, its a good thing to use disposable parts. Also note the latex gloves and eye glasses. Saftey first!
