Hoop Chart

A little hoop mathematics.

Figures based on 1" diameter tubing and spiral tape at an angle of 37 degrees and the spiral repeating every 4.25"

This calculates a distance of one spiral being 5.28" . It will require three 1" wide tapes slightly overlapped to cover the hoop.

All dimensions are in inches apart from the total length of tape required for each hoop.
