Jan,
Thanks for the information. When I was a boy, I remember a family trip to upper New York state. We visited the Corning Glass museum, a fascinating place. As a demonstration of how flexible glass can be made, I remember a constantly moving spring made of glass. While developing a lens cover for locomotive headlights (which could withstand the temperature changes), one of the engineers brought one of the light covers home. According to the story, his wife tried using it for cooking and Pyrex was created.
Glass has been a major material in my quality of life: eyeglasses, camera optics, fiberglass insulation (invented in Newark, Ohio, near my grandchildren's school), Pyrex, Corning Ware, and Corelle dishes, fiber optic voice and data transmission in my work at the telephone company. The list goes on. Soon to be added to that list will be a Pyroceram platen.
If the two ends of the Pyroceram platen piece are not slightly rounded, I plan to soften any hard corners with a diamond paddle. Based on only a gut feeling, I believe that may lessen the wear on the back of the grinding belts.
I plan to use epoxy as the adhesive to hold the Pyroceram to the steel platen. Any thoughts on adhesives?
It would seem prudent to order a spare platen through Steve. Following Rupert's suggestion, I may order two and shorten one to allow more convex grinding near the wheel.
Thanks, all, for your thoughts.

ps I realize a custom sized piece of Pyroceram is an unusual, specialized item, which makes a larger sheet smaller. I expect it to be expensive, and am not complaining. Three pieces of Pyroceram cost about the same as the basic Viel (without motor). I think the Viel is a real bargain.
