Helix Construction, temporary cardboard supports

Carved out cardboard supports using the measurements for a 7mm subroadbed and test-fit the spiral ramp to them. Putting a ramp onto supports is really a two-man job. One man with duct tape can almost get away with it, as seen here... This thing really dominates the room now
