This will be a very interesting thread, one I will be checking on every time I am here. I still get cold chills thinking about working with big sheets of glass, so I admire your willingness to tackle this.
Thank you Hoppy. You bet!!! that's why starting with 24" X 18" sheet (biggest one I have). Keeping my fingers crossed and see how it goes. If it turns out well, may be bigger ones and advanced tools in future.
