Fibonacci Bowl

[JayMan72]

Hey all.

I just completed my latest project.

I based the feature ring on the Fibonacci Sequence.

The main wood is Katalox.

The feature ring has 6 pairs of book matched Fibonacci Sequence pieces. These are comprised of Bocote, Aspen, Wenge, White Oak and Gonco Alves. The spacers are also Katalox.

The floating bottom is a piece of book matched Ziricote.

It is 12 inches across and 3.5 inches tall.

Finished with 6 coats of Friction Polish.

Thanks for looking.

An intriguing fact is each of the subdivisions produces a golden rectangle. This sequence is so interesting, there are several groups that study it and there is a quarterly publication dedicated to it. And it all started with rabbits...

 

[Jack A.]

Close but not exactly. The ratio between successive Fibonacci numbers approaches the golden ratio as the numbers grow larger. They can never be exactly equal because the golden ratio is an irrational number (can't be expressed as a fraction) while the Fibonacci numbers are integers, so their ratios are all fractions.

 

[JNCarr]

Yes, it's an approximation equal only at the limit. In fact the golden ratio can be proven to be the MOST irrational number!

Beautiful work... great job!

Your joinery is masterful And - a unique creation in the use of Fibonacci!

1. Excellent execution and finish!

2. Woodturning - for most - is about the pleasure and use of general principles ( i.e.- Fibonacci, Golden Mean, etc..) is not about strict adherence and advance math. While there are exemptions - those are far and away a smaller portion of turners. I personally enjoy seeing all things turned.

3. The confluence/interference of math and good form: (THIS will start a rock throwing contest if not taken in the spirit intended - which is observational WITHOUT judgment.) The French Curves as you can buy at Hobby Lobby, Michaels, or Amazon - do not have an "ugly curve" on them. A fine chain is an unbroken curve when the ends are held in each hand, allowing the chain to drape via gravity and unimpeded by contact with anything. Using these two items to pre draw a shape or to "sight across" can/will help anyone seeking to make aesthetically pleasing shapes. It is only one component of woodturning - *BUT* it is the first thing the brain recognizes, the eyes see, and if done well - compelling the hands to reach for or to touch the turned object.

Form, Fine wood, Finish. The 3 tenets of artistic turned objects.
