Fibonacci gauges
With a little brass to keep all happy…

I got some wonderful wood from my friend Napoleon, so I was talking to me!
I wanted for a long time to make one of these Fibonacci gauges / golden section gauges, and now I finally had some beautiful wood to make it from.

I made two, one with brass points at the end, so it can make marks in the wood, and a brass ring for the leather string to hang it on the wall. One with holes, so the marling can be done with a pencil in the exact points.

The small one is made from Mahogany, and the big one from some ….. (help me Napoleon!).
The screws are book screws. They open them self’s, so they are not really good for this purpose, so either I will epoxy them together, or perhaps use some of the stuff the car mechanics use to hold fast bolts (some blue stuff in a tube), in this way they can be adjusted later if needed.

As always I was helped by a good pipe of tobacco, and my Veritas apron plane produced some beautiful shavings from the mahogany that I had to show you (look at the glow-wauuuuu).

If someone wants to make these gauges, here are a few links:

(To you my sweet Rivergirl, no I just can’t stop making tools – I will seek proffesional help soon I promise).

I hope it can be to some inspiration, even we have seen these a lot before,

Best thoughts,

Don’t think you need to seek professional help, after all, your work looks VERY professional to me.

ahh fibonacci, ... the genius that has been guiding symmetrical designs by man and nature. perhaps the cosmos reflects this sequence. when in “design doubt” seek an number or ratio in the fibonacci sequence.

beautiful gauges mafe.

dont go smoking the mahogany shavings in your pipe.

I think the “blue stuff in a tube” might be called JB Weld?

Very nice Mads. I’m putting this in my favorites. I wonder if pop rivets would work well on this? Anyway, This goes into my favorites. Thanks for bringing this to us.

The blue stuff is threadlocker, as far as I know (in french, we call it “frein filet”, literally: brake for threads)

Love the brass with the mahogany!

Thanks Mads, because of you I can cancel my FWW subscription. You are far superior and in FWW they don’t cover the TOOLS as well as you do. AND for a Dutchman your price is much better, FREE.

Try loctite for your book screws. And if you use the blue stuff you can take it apart later.

Wow… thanks, Mads…. yet another device I need to build. I’ve actually wanted one of these for a good number of years. You truly are on your way to jigmaker’s Saintdom… And please DON’T seek professional help…

though I can see it now… you standing up in front of the crowd,

‘Hi, I’m Mads Felding…’, (crowd responds in unison, ‘Hi Mads’) ’.... and I’m a LumberJock…..’ ha ha
