The mouth mother mold is also made with the plaster of Paris wrap. I make a two piece mold for this.
As you can see to silicone mold fits into the larger portion of the mother mold and then the small fits on top. A rubber band will hold the mother mold together and then I can slush cast the mouth.
One thing I did on this mouth mold was to leave the brass pivot tube in the mouth when I first molded the mouth. I did this so I could cast the pivot tube in the mouth at the same time I cast the mouth. This is a time saver!!
