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.

Lifting the top of the mold to pull new part.15331 viewsLifting off the top part of the mold, you can see the new part in the bottom half.
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!
