Helix Mockup, cardboard

A cardboard mockup of my proposed helix / helix area. Looking at clearances against the workbench, the supports, the door, the access hole. Moved the helix towards the wall, to emulate a 4" straight side, and trimmed the overly generous angled side to check clearances a little more realistically Helix over workbench, looking down to check clearances Note three pegs. Left marks radius 18.75, the outermost helix track. Middle is 4" from that and right is 5" from middle and so 9 from outermost track. Note third peg visible at 1.5' from table edge and so 10" from radius 18.75, the outermost helix track
