| Okay this is the last part we will make a mold of. Notice the wax cup in the background. I do not recommend mixing stuff in the wax cups. Use plastic ones if you can. The reason is that when you are scraping out the last little bit of silicon, or resin, you will pick up some of the wax... I will be using wax cups... But as noted with the Beer, don't be like old ILAF... |
| Insto-presto.. the parts are wrapped in clay. What I am trying to show here, is build a good clay base around your part... up to the parting line. This is how come we can see half of the feet and the little white connectors. On the right you can see that I used the open bottomed electrical box, but only a portion of it. You do not want to pour more silicon than you have to. So I built a clay wall to contain the silicon to a portion of the box. Also note that there is clay sealing the box to the white plastic base. You do not want silicon leaking out of your mold box. |
| Just another view. Notice there is no vents or pouring holes (which would be pieces of wood or plastic). Right now you need to decide how you are going to pour in the resin. I could pour into the little white connectors... I would need some dowels to get positioned for this... But I have thought about pouring from the sole of the foot... This will reduce the need for vents..... almost. |
| Here once again is the head. Basically load the bottom of the cup with a layer of clay (thin), attach a piece of clay to the base of the head and stick it in. Center the head, so you have plenty of room between the cup sides and the head. Make sure you leave enough room above the head to cover it completely... at least 1/4". |
| AH!!! See the little pieces of wood dowels on the tops of the white connectors. Even though I plan on pouring from the bottom of the feet, I want to make sure that I can create a space for any air bubbles to form in the space created by this wooden rod. It will mean that I have to clean the connectors after each pour... but hopefully we will get good feet. That is more important than a bit of clean up. |
