A follow-up to a post by pviser on 5-30-12 about a new Woodpecker product: Fibonacci gauges.
It is an interesting topic that got my curiosity...like "what are these and what are they used for?" Too cheap to spend $50 for a 24" gauge and even cheaper to not spend $2 for a plan out of my monthly allowance from LOML! After a lot of looking and review of basic geometry and trigonometry the concept became clearer so it was time to make one.
SketchUp was immensely helpful to me, but it played a lot of mind games with me because of the angles, etc.
And the result is...
The actual measurements over a full 24" span are (14 7/8"/9 1/4") = 1.608 vs 1.618 theoretical. Close enough for guvm't work.
I'd round the actual measurements up or down for convenience anyway. So a 6' long tabletop would be (72"/1.618=44.5") wide theoretically. It'd probably end up at 42" or less in my hands. That 1.618:1 is a guideline, but not a rule.
