Excellent, Dave! Do you have any suggestions for particular acrylic and sealant products and sources?

I think there has been discussion about replacing windows, maybe applicable to Montgomery 15's but I can't find it on the photo site and am having trouble downloading the entire history of this group to search, so I'm going to be lazy and ask here. I assume I'd need to fabricate them, so, some questions: 1. What is the best material, type and thickness, for example?2. What is a good source for the material, including tinted gray?3. I hope I could duplicate the shape of the old windows with a pattern bit on a router but wonder if that would melt the material to much. Any suggestion how to cut them out, bandsaw and a file?4. It appears the windows are beveled on the inside of the edges and creating that bevel could create a melting problem like cutting the windows out. What is a good way to create this bevel? Any experience and suggestions are welcome! David GrahBishop California
