Created the circle, from this, we have to create a spiral. The steps to follow are the same that you can find in the post "HOW TO CREATE A SPRING WITH SKETCHUP", would not explain them again.

It 'important to create a group of one of the two models, in this case, my group is the spiral. This is to avoid that the two models, when superimposed, is intersichino between them. Then we position the spiral over the cylinder so that the segments coincide perfectly with each other.

We click on the instrument "Move" and then on the group spiral with the "CTRL" key to create a copy, spostiamola down along the blue axis until it reaches the center of the original one (see image below).

Now we can explode groups of spirals so as to intersect the segments with those of the cylinder.

We click on the spiral just created to highlight it , then the instrument "Scale" and finally, with the CTRL key pressed on the handle of the solid angle at the center, ...
