Some shots of modeling the clay. I have been using a product that Composits One puts out called Permoplast that I really like. I use a heat gun to soften it and then run various sized sockets over it to get the desires radius.
A shot showing how strong the core cell laminate is. I'm about 190# and the thing does not flex at all. There is only one layer of 1808 on each side of the 5/8" core cell.
A shot showing the 3/8" lip that Hermco and Kneedeep are talking about. There is a clay bevel on the underside of it so the glass will contour up and over this to form a recessed pocket.
The mold is ready for wax and PVA now.
