Golden Mean gauge

Jewelry Discussion
1

Came across the Golden Mean gauge while researching the Fibonacci
Sequence and Golden Ratio relationship (for my jewelry design).
http://www.goldenmeangauge.co.uk/golden.htm Does anyone use it on
their day to day operation and if so, how? Also, do you have a less
expensive source here in the US? The aforementioned website in the UK
sells it for roughly $90 US (too rich for my blood :wink:

Thanks.

A coincidence-- today I was making some canvas stretchers for my
daughter to use for some paintings and mentioned the golden section
to her as a way to size them. A while back on Orchid I
mentioned proportional dividers and the thread ran for a
whileā€“see: http://www.bridgecitytools.com/

The item is #1101-157 PD11 proportional divider not cheap but
VERY nicely made. $207.20 US

see their ā€œsneak preview 56ā€ on the site for more on the tool
and the golden ratio.

The tool is on their discontinued list but still available. It is
a work of mechanical art good for a lot of layout uses.

Google will find more on the golden ( perfect section) mean.

This subject of Fibonacci and the golden mean is very interesting to
me. I wouldnā€™t mind having one of those gauges myself. And I agree
that they are very pricey. I donā€™t know if the design for this tool
is patented or not but it seems to me that one would be able to use
a pantograph and transfer the tool layout and make one for yourself.
I may give it a try myself. Pantographs are available for less
than $20 US from several tool websites.

Proportional dividers

The base design is very old ( 150 years? + ?) . The Bridge city
one is a tool made to be a pretty and has very well built
position locking. I have one but didnā€™t really need it. It is the
third one I have bought. The first was in Tokyo about 50 years
ago and things there were very cheap then even with army pay (
may have been about $3 US equivalent then) . The second is a
little larger and was bought in the US about 30- 35 years ago for
at least $100. They were and still are very handy for scaling ,
but there are other easier ways to scale stuff now. Computer design
programs , scanners and variable size photocopiers can do the
job. There never would have been a big market for these. Easy to
make in a crude form . The preset balance points make the BC one
much more useful but harder to reproduce at a competitive price.
