Golden rule calculator, Fibonacci

I quite often use the golden rule for making projects and have found these formulas useful . When I want a certain size, and have one dimension (Width, Height or Length) I'm going for, I can plug that number in which will drive the other dimensions needed. Putting this into a spreadsheet makes it a piece of cake!

Known dimension = H, W or L

HEIGHT = H, Width = H x 1.628, Length = H x 1.628×1.628

WIDTH = W, Length = W x 1.628, Height = W / 1.628

LENGTH = L, Height = L/1.628, Width = (L/1.628)/1.628

i only use one rule for making projects thats,there are no rules.i design based on what looks good to me,but those formulas are great for most people that cant visualize a finished project,

Well believe it or not the concept of,... it doesn't look right, ... is an visual application of the Fibonacci rule anyway.

To prove it to yourself draw a few boxes on a sheet of paper in the 2D realm or 3D if you want, and the choose the one which looks pleasing to you. Ignoring of course making a box for your Barrett M92
Then measure it, and you will find that it will be very close to the 1: 1.62 ratio !

Amazing stuff eh!

I made a Fibonacci gauge but like you I don't use it much, .....well sometimes I do just to remind me of what the Fibonacci theory is and how it works!

And I guess people (outsiders) look at us and wonder what the fascination in woodworking is!

rc if you saw my process for designing and building youd shake your head and laugh.most projects are a simple sketch with some basic measurements at best.i design and build 90% in my head.the time some guys spend doing sketchup ill have the project half done.thats just my way,i dont recommend for anyone.

In most cases the only drawing I do is after the fact so I can remember how I did it if i need to repeat the project if I have given it to the family. I learned my lesson big time making Maloof kids chairs!

Hey rc, pottzy is upset because no one has designed a Fibonachi gauge for bowls.

I made one after inspiration from Dave Polaschek

I've visited his home more times than I've used my gauge… and he wouldn't even answer the door to let me in.

Correctamundo pottzy... all the commoners have bowls, it's the elite that own and can solve puzzles… most accept being puzzled by a puzzle but few can accept being puzzled by a bowl… unless you're a cricketer line Shane Warne!

No way Jose and that's with a capital "J"... cannot stand the three of them… K, K & M... just typing that makes me cringe at a "&"!
They're about as funny as an impacted wisdom toot extraction without anesthetic… and I had one extracted that took 2.25 hours… yep… but I had the funny juice so the first 2 hours was ok… it was the last 15 minutes when I became "immune" that it hurt big time!

Benny Hill was crass… in a good way… they are just crass. I wouldn't watch them even if they were in a XXX... add another X and I'd still boycot (not Geoffrey), however, Warnie by himself, maybe!

Thanks for postings. Formulas like these, much like cookbook recipes, a great jumping off point for inspiration and individualization.
