I have taken pics of the prosses I have used as follows.
I random carved it with a Arbortech carver they cut the slots at random on the Bandsaw.
I decided that the whole centre done with Pewter was a bit too much I am not sure but anyway I decided to create a ring so that the two areas of wood would set of the Pewter
At this stage I still had the other side to do so I thought instead of casting the ring in the piece I would make it separately and then fit it in the recess .With a separate piece I have turned a recess a little over the size I will eventually need to give me scope for trimming up
I have created a flat on the bottom of the mould so that I can hold it safely against the belt sander
