Tesla Coil TC4I was my second coil, made from plans found on Gary Weavers site. I went through numerous pages and his seemed to be one of the better and more complete sites. This was the first coil we used in the Haunted House (Agnes wasn't complete yet) It was put behind a hand built electric chair with a live monster in it jumping at the people. I must say it was one of the better rooms.
