I've had a CarveWright carving machine for years that I've made many carved signs etc. I've always wanted to carve something and then cast the resulting carve. I finally found the time to do it and will try to illustrate the process for those who might be interested.
I started with carving the address plate in HDF (high density fiberboard).
I next place the carve face up in the bottom of the casting flask and pack with casting sand.
I then flip the flask over and apply the top part of the two part casting flask. Chalk line powder is added to keep the top half from sticking to the bottom half. Sand is then added and packed in the top half.
