I've been learning to engrave metals and its all about scrolls in that medium so I've seen the Golden Mean discussed a lot in those forums. So when I read about it and all the math came up in the discussion smoke started coming out of my ears and I had to back off. But I asked my daughter with a MA in fine arts about it and she had learned about it in school. It's kind of like the Supreme Court trying to define pornography " We can't define it but we know it when we see it!" It's like one of the other posters said, "now we know why somethings just look better than others!" The cool thing is seeing how it occurs in nature.

That's the truth!! LOL Something just seems off it the curve isn't "continued as Paul Burnett said. Now we know why. I've still not experimented with the Curve posted above. one thing I notice is that you can use just the curve closest to the center of the spiral and it's the same shape as the entire thing. That means that the curve could be sized up and down without having to do a lot of editing in a program.

maybe I'll start with slug cats. :D

You might want to look up another subject Burnett discussed in his free tutorials. Hogarth and his lines of beauty.

You can make your own "Gloden Mean" calipers, which I suppose you could scale down to make a set to allow you to lay out your Sheriden patterns if you were working freehand rather than from a template.

Available via Etsy: http://www.etsy.com/...ers-small-114cm
A New Zealander makes 3 sizes of metal calipers, look pretty nice too. Not a bad starting price either.

Hmmm... $45 shipped. I just couldn't do that. I would rather try to buy American anyway.

Thanks though! I appreciate your looking out for me! :)

No problem. If you discover and American craftsman that makes a quality metal set, let me know. I've searched and there just aren't any.

Tell you what... I will ask Black River Laser if they can. I know they cut and engrave metal, granite... and a bunch of stuff.

I recently asked if they can make a set of "sine wave" rulers. Something with a nice undulating line....in various frequencies.

I'm not fond of math either. It's not something most of us would go hmmm that's beautiful because it's in proportion... or has golden ratio spirals. But when we don't see the proportion or the spirals aren't right.... we notice something is just "off" about it.

Luckily you don't have to be a math wiz now. I've had a template maker fix me up with some spiral templates. I got them yesterday and boy are they helpful!! It's a set of 8 templates for about $20 shipped. I spent some time yesterday fiddling with them on paper with colored pencils and wow... so easy to make scrolled designs!

There's another post that is about the template maker... http://leatherworker...11

Art has to fit Divine proportion(Golden ratio or Golden spiral) or you will have to violate it in such a way it is obvious of what your doing. If not the piece of art doesn't look right. Basically everything in nature fits the ratio 1.618033......... Pine cones, sunflower seed pattern, number of branches on a tree, number of leaves, circumference of the earth, planetary orbits, planetary distances, there are stock market prediction algorithms using this and the list goes on. It is an amazing phenomenon.
The math isn't as hard as you think it's like this:
Starting with zero add the numbers on either side of the =.sign Then divide the smaller number over the larger number. This can be done quickly on a spreadsheet program
0; 0+1=1; 1+1=2; 1+2=3; 2+3=5; 3+5=8; 5+8=13; 8+13=21; 13+21=34; 21+34=55 etc I have attached the spreadsheet to see how it works.
