This is why I like watching your videos on RUclips +Steve Ramsey; I have never heard of a "Fibonacci Gauge" til now and this video is almost 9 years old. As soon as I get my table saw working correctly, this will be a most have build.
As a math teacher, I love that you used the clips from "Donald in Mathmagic Land." Side note: I don't know how stiff those rivet joints are, but it might be a cool addition to replace one with a bolt and knob so you can tighten the whole thing in position when you make one measurement.
Or stick a washer in between the wooden arms
Hey, I've used this video as inspiration for a mroject with my students. I teach geometry at a Philadelphia Charter HS, and I lead a project where every student leaves with ove of these to keep (not out of lacewood, mind you). Keep up the good work!!!
@welchclae Go to the link in the description box. On that page there is a PDF and a Sketchup file.
@Geissler745 Yes, but it's a dry rain...
These would be handy for artist to have. Especially those studying Phi as a ratio in art history.
That said, there is no reason you can't make others that have fractions scales to make scaled models of existing measurements. Ones in 1:3 and 1:4 might be useful (they'd also scale things by 3 or 4 if you start with the small jaws).
I also think it'd be nice to make callipers that always point to the center of the span for dividing things in half.
Correct ratio is: KLAATU! VERATA! NIK>>kough
The link to the template download isn't working at the moment.
Thank you. This is an excellent tool both for drawing and woodworking design.
Wow! Pretty darn helpful! I always knew the off center proportions were nicer but leave it to math and the Greeks! Great video
Thanks stevinmarin!!! I´ve just made my Fibonacci Gauge after I watch your video.
Greetings from Brasil.
Watching you're older vids... dude u have always been funny as hell!
@gunhimdown Yup
please, template?
Hello Steve, love this but I tried to follow the link to your page but it said the page doesn't exist. Is it no longer available? Please advise a mere mortal from the UK.
I'll definitely be making one of those, thanks for the vid.
Tried to find the drawings on your site and couldn't. Can you make this available again?
I love your enthousiasm !
now this one i might try, it would really help me! am i able to do this without any of those mechanic tools?
Hey Steve...Great video...Two questions - what size rivets did you use and what size holes did you drill? Thanks for the great videos!
Thank you for this great project Steve.
Numbers are fun :)
Im going to make one of those. If u use the gauge for the say lenght and width. how do u determine the right height??
Your video was fun to watch, you have a great personality! Rock On!
Ever thought about making a sector? Really cool and useful tool.
now this one i might try, it would really help me!
really handy to know considering the price of these on eBay for some reason I can only buy one from the US at $14 but it's £10 p&P so £20 for something I can make for less than £5 this video helped a lot
Hi Steve!
I share your admiration of the Disney cartoon about "mathemagic." I thank you for bringing that to others' attention and for this primer of golden ratios.
For your info, PHI is pronounced "fee" and the ratio is 1:1.618.
Hai, your template link is not working. Greetings Rob.
it just so happens I hav a few scraps of lacewood laying around my shop looking for a project....this is it....if I am not mistaken, I have a WOOD magazine with the plans for a fibonacci guage as well as several mathmatical formulae concerning the deapth of drawers. I will see if I can dig it out.. Thanks for the podcast.
+Steve Ramsey Do you know the source of where to get thos Rivets? Since this video, I've been on the Hunt, I never really knew what they were called. I've got some Knives that need Repairs and I'm interested in Building one of these Gauges for myself.
really cool vid! great info
Yep i sure do remember Missing Persons! Destinations Unknown was one of their best songs, Spring Session M. Remember the US festival?
I didn't find too, the link doesn't work. Please, I'd like to make one.
@Eric333333333 Ha! I almost did! But I suspect I am far from phi.
Where can I get the rivets that were shown?
Appreciated! It is still available. Thank you for sharing.
Link does not work...
Fun and great video!!!! well done sir ...
@RemoteHogg10 I'm not sure what size they were, but you can get them at Leevalley (dot) com
did you by any chance use lace wood??
Hi Steve. I enjoy your videos. I made one of these gauges yesterday. A quick, fast & fun project. Have you thought of incorporating the design into your logo?
+Ken DeHaas where did you got the plans from? As said in the comments below, the link is not working so you may have a link or a drawing?
@Sodabowski Quoting Malibu Stacey: "Math is HARD!"
Vc tem bom gosto! Eu também gosto do som da Missing Persons... Trabalho sempre ouvindo new wave ou new age...
what is the measurement of fibinacci gate please?
@RUIuiuiuiui This is a project you could most definitely make with hand tools!
nice
what if you want to make a bigger furniture say a sofa for a small room like the one Mexican houses built wich is very very small and need to be proporcionate to the house. So it dont look to big acording to the size of the room wich is always the case here
I Just Subscribed to your site after watching this video, so that all said: My name is mike; as always, thanks’ for taking the time to make this video! And I support this site. ~M~
Ps; Look forward to watching more.
wish i had "scrap" lacewood!!!
Golden mean: 1:1.618
This is the ratio of any two consecutive Fibonacci numbers. The larger the numbers, the more accurate the ratio. Fib numbers are numbers in a sequence starting with 0. It is a progression of the sum last two consecutive numbers. 0,1,1,2,3,5,8,13.... etc up to infinity.
PLEASE ASK IAN where he bought his Boston screws! Even Lee Valley (specialty hardware store in Canada) never even heard of them! I ended up using wire (from stripped down twist ties from a bunch of broccoli) and 8 two-holed shirt buttons! I could not find Boston screws ANYWHERE in Vancouver, BC after carefully drawing out the pentagon with compass and straight edge and labouring over matte boards to cut out my 4 caliper arms. Sheeesh!!!
Thanks for the Donald Duck reference! Just what I needed...I want to get my grandson interested in math! But, first the Chinese Abacus (the Japanese style one is harder for a kindergarten kid).
Education AND a project!! Bonus!
Can't find the template on your website. why is it so dam hard to get plans for one of these?
Could the Fibonacci sequence be formed by the spontaneous absorption and emission of light?
All the info I can find says that this process is formed by the quantum wave particle function Ψ of quantum mechanics. When this is reformulated as a linear vector ǀΨ (t) > the two previous vectors are added together to form a new vector this forms the Fibonacci sequence 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ∞ infinity!
This is an invitation to see an artist theory of the physics of time!
What is sketchup
love your truck
Very excellent sir !!!!
Steve, does the golden ratio please the eye naturally, or have we been trained to choose those ratio's to like the most because every bugger has been using it to design stuff for eons? I've downloaded the drawing anyway Steve thanks. Call in for a brew if you're in the hood. Manchester UK
I was just thinking this. A system always works and i guess since its all around we have trained our eyes to it. We just like consistency.
It is naturally pleasing. That’s the whole point.
Okay I give up, where do I find the rivets you used to assemble the parts?
They are called compression rivets.
You have good taste in music. Great video.
+1
Anybody got plans with the size in the metric system????? (I'mm from germany and i always have to think how big your projects are....)
Sebi Land search for fibonacci gauge or phi calipers in google images. You will see a nice, clear and simple illustration for measurements.
Just use imperial side of your gauge, I do the same sometimes when I need. (Metric system in Brazil)
www.goldennumber.net/do-it-yourself/
@sappha58 That would be nice.
@wdworking Show-off!
@Buzzsawman Yes! Wood Mag is the best. Check out the related video over there ---->
"Fibonacci Gauge" by RUclipsr, "sonouhuru". He does a way better job at explaining Phi and how to use the gauge in your designs.
That is if u express th sin^-1 in radian.
Its not so suprising that u could find a relationship between an angle (54deg) (expressd in rad) and phi when "radian" IS simply an expression of that angle as a "slice of pi". (-; In other words, in ur attempt 2 relate pi as a calc on phi, u essentially inserted pi into ur calculation. That seems so no-no (-;
Yes, sin54deg=1/2 phi, and also sin18deg=1/2 of 1/phi, so naturally 18 in rad is 1/10 of pi. (just as 54 in radian is 3/10 of pi)
This is kind of irrelevant, but what was the song playing around 6:40??
Hi Steve! I have a question for you, i dunno if you'll ever see it, but one can hope. Q: Why are you so awesome and hilarious?
I could not find the plans on your website.
Click on the link from above. It is there, because I downloaded today. 2/22/22
it would have been nice if you had mentioned the various lengths of wood you used.
R'Lee Serratt 34cm, 34cm, 21cm and 13cm.
Tks Steve.
Really enjoyed this one of yours Would it be possible to get the email of Mr. Waltinberry address for the brass rivets that you use
thank you I am from Mexico and hardly anybody knows abou it I always wanted to get me one
It is 1 to 1.618
there's all types of metallic ratios, you should try a pair of plastic ratio calipers.
Please, what type of wood used?
I want to answer at the earliest opportunity
Its called lacewood.
Note that you could have had your answer immediately if you had only paid attention to what was said in the video.
Hey Steve, I have a challenge for you. How about making something that will fold newspapers and band them? Can it be done with wood? I had a few ideas but they went in the round file. (I'm just a beginner woodworker).
okay - I'm going to build myself some of these and use them to build better CIGAR BOX GUITARS !!!! Thanks for the GREAT IDEA !!!!!!
@prenosilj124 Yeah man. 2x4s.
Thank you for giving us this info. I wanna make some now. I've got pop-sicle sticks.
;-)
@howtomakewallets RUclips knows all...
It is 1.618......
I have that movie, I love it!
Anyone have an idea what these rivets are called? I can't seem to find them at stores.
They're rivets used for attaching knife handles to knife blades. Ask for rivets for knife handles.
+Jeff Meyer A MUCH more affordable alternative are the exact same rivets made for brake drum assemblies and you can get a handful at any auto part supplier for a couple dollars. They're metal so lacquer them but they shine up and would work too.
Cutlery Rivets
It is 1 to 1.618... or just 1 to 1.6
I found it...it is the November 2006 issue of Wood. ..It wasn't hard to find. .the issure is pictuered in the list of additional information down the side of my screen. I knew I had it somewhere. I NEVER throw away a woodworking magazine....one of these days my house is going to collapse outward from the weight of the magazines.
I would like to download it but no exist!! :O
hi ramsey
But may i add--ANY two numbers as a starting point converges on phi in the same way, and basicly just as quickly!
But seeing that u r likewise somewhat fascinated by this subject, pardon me for presuming to lay this one upon your fertile mind:
1/(any phi^odd) = (the decimal portion of that phi^odd) !!
(any phi^even) = 1/[1 - (the decimal portion of that phi^even)] !!
Such elegance!
(,;
good work steve how come you never replyed to my pms .did you see i mentioned you in my chopping board vid....
cheers sam
when i made mine it turned into fugazi gauge. i messed it up some how :(
Dude! I not only remember, but I had an album by missing persons. Remember those?
Credit card dimensions are actually 85.60 by 53.98 mm, so their aspect ratio is 1.5857725. The "golden ratio" (phi) is 1.618.
visually appealing, not mathematically appealing
Depends on how high the credit limit is. ;-)
I miss the old Steve Ramsey videos.
Rivet number 2: Uses pliers, Someone's thumb hurts? :P
hehe, thanks for sharing this video! Interesting fact about the credit card too!
I just made Fibonacci calipers for my brother (who I'm flying to see for Thanksgiving) and was looking at it thinking: I wonder if they're going to let me carry this on the plane?
Great
i think its something that we do without thinking
like marching in step with others
You a genius
Ya gotta love a guy that includes both Donald Duck in Mathematical Land and Sketchup in a 7 minute video.....
@JoeCubicle You are now excused from class.
@specialks1953 Well, you see, math is a simple matter of...wait, what. Beer? Oh yes, beer is the basis of all modern culture and...wait, what were we talking about?
