This spiral playlist is exactly what I wanted to see thank you much

[@guitareputz]

very kool!
I'm trying to figure out how to make a "cam clamp" to hold material in a CNC machine. I know that a cam is a spiral ...but, What type of spiral would a cam clamp be made from?
Thanks so much

Thanks for the video, but shouldn't you point out that this an approximation? No section of a true log spiral can be an arc of a circle. Or am I wrong?

[@seanclark2703]

you're not drawing a true one by hand anyways.

How about a less cumber method based on an "infnate long rotating about orgin at a constate rate, and traceing a line from a point that is moving out at a constant rate of acceleration?

Thank you!

How can I draw a logarithmic scale. I want to build a Cabinet Maker's Sector as is shown in the following video. I believe that the the Line of Polygons scale on the Cabinet Maker's Sector is the logarithmic scale. Any help will be greatly appreciated.

How did you determine the radius of the arc centred on point C at 5:10 ?

[@mueezadam8438]

Beautiful

[@dreznik]

this is not a logarithmic spiral. this is a concatenation of circular arcs which approximate it.

[@samisiddiqi5411]

OB/OA is the constant

Vel'koz main since beta

So confusing. Just use Vesica Pices.
