	That's a cast iron tool, fellah! Welcome to the real optician's "lap"! ************** A good exercise- machine it convex to a predetermined ROC with your handy flycutter, and recut the concentric grooves to do mirrors. It'll hold the ROC far better than any glass or tile tool. Or you could also machine and grind it in flat for doing such pieces. Nothing like a good cast iron tool. Mark
