Nick wants to hear from any reader who has constructed a helix and asks:

“I want to build a helix, but am having difficulty getting comprehensive information. I have, however, discovered it will need to be a minimum diameter of 5 feet. I have also discovered that hardboard (subfloor sheeting) is the prefered substance to use. There are several schools of thought as to shape, risers, etc. So, the question is – Are there any plans for the construction, or will it BE, mostly trial & error?”
