Spiraling Challenge

[Fleming]

A contractor friend asked me to carve a beaded spiral for the capitals of some columns he was building.
All he had was a sketch and some rough dimensions.

Original Sketch

I was able to duplicate the outside of the spiral pattern using the Spiral Gadget

Generated Spiral

but the challenge was having Aspire produce a parallel spiral exactly 1/2" on the inside thus forming the 1/2" raised area for the bead. The final
result:

Final Bead

It took a number of steps to get Aspire to produce it without me trying to trace or draw. Is there an "easy" way to do this?

It will make them parallel, but you will need to scale the spiral to get the spacing to be 0.5". Use the Archimedes spiral type.

I used this gadget for the first time just yesterday to do it with text. The text was spiraling outward from the center. It took a minute to figure out that all I had to do to reverse the text direction was to node edit the spiral to put the start node at the outside end of the spiral. This is a test to get it to spiral correctly, and the text and the font style will change to something else.

Try using the "ARCHIMEDES" spiral, for the first layout, then the "OFFSET" tool. It seemed to work for me.

THANK YOU! Those techniques are much simpler than mine
