WOW! That is cool and a wonderful job. Ha, I would still be working on the bottom section! Truth be told, I don't think I would attempt the project. Cutting straight lines a 45 deg. angle on a scroll saw would have to be very difficult, especially the length of the cuts you were dealing with. Those cuts would even be difficult on a table saw because they are compound cuts,
Well done, Dick. I do not see where I could help you. Congratulation on a wonderful piece of art!
