Topic tags/keywords: question lathe

Does any one know how you would use a Fibonacci Gauge for Wood Turning? Like what would you make the ratio of width to height? Wide part to narrow part of a vase? I saw a video once where the turner put the gauge up against the piece he was turning, but I could not see what he was comparing? He did not go into any explanation either.

Anyone know how it would work in relation to turned pieces????

Thanks, JIm

I would consider using it to mark where you would cut grooves in somthing like a table leg. You might get away with using it for turning a bowl with and depth maybe?? However the use of math would save you from using the gauge. I’m not a turner and I don’t know a lot about the Fibonacci Gauge.

Have you heard about the golden mean? It’s all about proportions – 1 to 1.618 – which most people find pleasing to the eye.

For example, if you use the gauge when making a box, use all three arms for the length of the box and two arms for the width. Looking at your projects, I think you can do it intuitively.

Let me know if you want examples – I’m too pooped to do math tonight.

Yes, if oyu want the next Golden Value Higher, multiply by 1.618…
... if you want the next Golden Value Lower, multiply by .618…
Bowl Diameter x .618 = Golden HT. (depth) I would think…

Jim, it is a good measure to think about as long as you have a logic approach. It doesn’t suit all circumstances but can be applied in turning.
I have used it for small turnings like tea-light holders and screw top boxes.

I mostly use mine like a skew, but can also use it like a parting tool.

If understand rule of thirds or breaking size of elements into thirds Fibonacci gauge works well on most turnings. On large bowls and hollow forms may exceed capability of your gauge unless flip-flop.

You can open or close your gauge on a piece of wood mounted on lathe to show you length, width, and height of an element in relation to other elements. You can measure points of gauge with a ruler and record them in mind or on paper.
Russ explains rule of thirds, with bowl as example. Use your gauge to determine dimensions for your project.

http://www.woodturner-russ.com/Design-2.html

Open gauge, measure & mark where want stuff to be, turn and check with gauge. What no math required?
Other than using a ruler to measure points on gauge and wood guess not.

Do not need the quage to figure thirds, but does make it easier and fun to play with. So just have fun with it.

I really can’t see it working for turning, all bowls would look basically the same, just look at your own turnings Jim., each one artistically made to suit the dimensions of the particular blank. For the likes of furniture, buildings etc. it’s magic.

You can still use a scale for large projects. The Fibonacci gauge is used for design meaning you could have an option of drawing before you build, using measurments to put your ideas to wood.

Rude Osolnik taught about breaking projects into thirds to arrive at a pleasing lines, balance and proportion in everything you turn. While a Fibonacci gauge not necessary will speed thing up on a lot of projects.

It took me longer to download plans and make my Fibonacci gauge than learn how to use it. Fibonacci gauge for more than just bowls. So, whether turning bowls or spindle work; change proportions simply opening and closing your gauge. If making a lot of same items do not change settings.

Marking out major dimensions along length, of spindle turning project provides proportions. Depending upon size of wood and design features checking circumferences may or may not change gauge.

Regardless size of bowl blank can mark off three dimensions bowl body, inside opening, and diameter of base can mark on or off lathe using your gauge.

Taking a gauge to the lathe with wood mounted and little help from pencil & ruler vice checking plans or drawing makes life easier. Give it a shot.

I think it might make a bit o sense, but, I’ve never heard of it being used in turning, to my knowledge. I’m not a super-practicing turner tho. I just turn a little here n there.

Woodturners that make them, leave hanging on wall or on a shelf in their shop 99.9% of the time. Dummies like me found out will give you great proportion if use it once in awhile. No, do not use it daily but does make me look and feel smarter hanging on peg board in shop.

Hi Bill. Mine sits on the desk with the 3 corner square and circle templates and the protractor where I do all my designing. I’m an old fashioned designer- no computer in there I had a vessel planned and wondered if I could use it on that to make it a good looking piece so I asked the question and I like the answer with the rule of thirds for turnings!!.............Jim

Thanks for the link Wildwood. I like the explanation and diagrams
of thirds in wood turning, very informative.

Here is a nice article on “Woodturning Design,” by Laura & Barry Uden providing good read.

http://www.westbaywoodturners.com/tutorial/pdf_files/Woodturning_Design.pdf

Of course no mention of a Fibonacci gauge, but do discuss various ratios and formulas for arriving at good design. They do not mention design software, but don’t say not too use it. Can buy a plug in for sketch up which says will help you draw up a plan.

http://www.turnedoutright.com/woodturning-products/modelling-woodturning/

I can spell sketch-up and that is extent of my knowledge on software.

Many woodturners do not worry about golden mean or rule of thirds, elements & principles of design and produce pleasing balanced forms. Too many wrapped around the axle worrying about design and listen to people that just talk about it.

Yes, I like and use rule of thirds on some turnings but not all because, just a mental exercise for me with ruler, dividers, inside, outside calipers and pencil no big deal.

Just get yourself organized however your comfortable with whether need detailed plan or design on the lathe with your tools.
