WoW !!! I have done glass for 2years & have not attempted anything round because I'm no good at math, trigonometry I couldn't do it, unless I good get a copyright pattern. You are a true artist all the jigs & working out & also making it work as a light, I'm in awe & inspired, thanks for sharing 😊
Again, thank you for the comments and the complement. I'm very happy to hear you enjoyed watching the video. One does not need to be "good" at math so don't let that hold you back. There's lots of good RU-vid videos to help with trigonometry and math specific to the situation.
Out of an abundance of caution I prefer not to show how the electrical wiring is done. That said, I used a 6" long tubular shaped LED bulb in the soft white spectrum. I get different shaped patterns depending on the shape of the bulb. Its very interesting.
