GR8HUNTER (Tony) jogged my memory on the Fibonacci gauges I made and never posted. They set the golden ratio for a pleasing appearance to a project. I use mine quite a bit especially on tops and cabinets. I have two of them . The last photo is the small one and it was the first. It is made from walnut and is 8" long and has pop rivets for pivot pins. The larger one is 17 1/2" overall and is made from Pistachio.

Haven't seen a Fibonacci gauge for a long time. Do you find it useful? Here's a link if anyone want to make one: https://files.woodmagazine.com/wp-content/uploads/pdfs/sites/49/2021/10/26/DP-00522a.pdf
To me, pop rivets sound scary (without the snap & crackle) for establishing correct pressure... be an issue if it was Lautrec... never considered them when I made mine... nor did I know about Chicago screws. I opted to make mine out of (surprise) 2 laminations of 3mm MDF. Each of the layers permitted me to recess both the countersink bolt head and the nut to permit pressure (re-)tweaking,
I used a wingnut on one of the fastener sets to lock it down... hate loosing settings between operations.
If your first cut is too short... Take the second cut from the longer end... LBD
with the pleasing aspects of the golden rule its surprising that the standard common as house brick does not conform, but the frame of our rectangular light switches does ...just a bit of useless trivia.
be Thanks you for all the informative comments. Hi Rick, I use mine at the drawing stage unless the project has to conform to given sizes by the customer.
Hi Alex, for my good gauge, I made brass shoulder nuts and common pan head screws for the pivots. The first on was practice!! Hi Rick, the idea is the things you make with the bricks are to made to the golden rectangle for the best pleasing appearance.
