Casting the Earlham Castoroides, Part 6

Ray and I took it a bit easier today, only working 6 hours instead of the 10+ we’ve done every other day. Even so, we managed to get a lot of work done, particularly on molds.

The first task this morning was to make plaster and fiberglass mother molds for the cranium (above) and mandible (below):

Thin-wall molds such as these require a rigid mother mold to help them keep their shape when filled with liquid resin. Once the plaster dried, we flipped each piece over and prepared it for pouring silicone on the other side:

We also flipped and poured the second side of the molds for lumbar vertebrae 3-7:

…and the left foot:

Tomorrow we’re planning another full day, and we should be adding a number of casts.
