Hello everybody!

I have to do a circular slide rule. Is there any nice way to make the logarithmic (circular) scale with Illustrator?

All ideas are welcome! Thanks in advance!

Here's a picture that shows what I am looking for:

You could use the Rectangular Grid Tool, with one row and however many columns you need. Then you can use the Skew option if you need the non-linear dividers:

Combine a number of grids to create your ruler:

Create an Art Brush from your ruler by dragging it the the Brushes panel and apply your brush to a circle:
