Hello,

Would it be reasonable to accomplish the weight reduction by making a series of more or less flat bottomed holes in the back of the blank? I'm thinking of a drilling tool that would be a tube with a semi circular flat bottom. Maybe turning in a drill press with the glass under a slight upwards spring pressure? And appropriate grit and water of course.
