Reply to "Double Track Helix Question"

Dan65trainOGR Forum Member

Our Train club has a 4 track HO Helix. It's about 6 feet across at the minimum and rises 6 feet. Circles over itself about 7 times to get the elevation. The people who made it at the club used plywood cut in arcs and used long pieces of 5/8 threaded rod as supports. Probably around 20. That way they didn't have to be exact with their starting level and the finished level. Used a nut under the plywood arc and on top. To fine tune for the elevation drop and raise they adjusted the nuts up or down to get everything smooth.
