Progress is slow. The master wax pattern is placed in a flask (used a 10 oz soup can)
The investment (plaster) is mixed in precise proportion.
Then the molds are degasseg in a vacuum chamber on a shake table.
And cured at room temperature then baked in incrementally higher temperature to solidify and to melt out the wax (lost wax)
flyingtractors1:
Now while the mold has been in the oven, I found time to work on other essential parts - the nuts and bolts of it all. Three sets will be needed. I could have purchased these components commercially; in fact, I do have some on hand - 2-56 threads at 1/2 inch long. But I am after an authentic look like an old vise in the barn. So I've decided to make my own hardware of square head bolts and square nuts of silver since I don't know where such can be found and wanted the total experience.

The casting of the master pattern went well.
And when the mold was broken open it revealed a good cast. It looks a little crusty but will clean up nicely.
Next comes the creation of the rubber mold for the production of soft wax patterns.

progress every day. The rubber mold turned out good, and nice soft wax patterns resulted.
