09 Plaster Production Molds Nº 39
Today I carved the spare. Plaster is homogeneous. That means there is not any grain, or hard and soft spots. I used my paring knife to carve the spare. That is the only tool I used. I started out by carving each end of the spare. One end is small, and the other end is larger. I followed the layout lines I made yesterday. Click on any image to enlarge it.
Once the ends of the spare were carved to the lines, I worked in the middle. As can be seen in the image below, I worked from the middle, out to the side lines. The important thing is to maintain draft. Good draft means not having any undercuts which will cause the spare to stick in the mold.
I carved one side of the spare, then the other side, using the same method.
The small end of the spare looks like this, from inside the mold.
The large end of the spare looks like this, from outside the mold.
