new brooch in progress

I started on a new brooch yesterday. Currently I have at least 5 brooches in progress, including this new one.

I started with 1/2" thick aluminum, and milled it down to about 3/8".


After I milled the metal to the right thickness I cut out the shape on the bandsaw and refined the shape with a belt grinder.
This is the pattern I will carve after I have the overall shape finished.


The piece will be sort of domed. Here I am about to start grinding it.
This is where I am at right now. I will post more pics as I work on it.
