Usage Notes

Pumping & a Curvilinear Slide

If the artist is using a curvilinear slide which produces a curve as shown to the right, then the cutting action on the left will be the inverse of the cutting on the right. (This inverse cutting relationship is equivalent to cutting on the near side vs. cutting on the far side when rocking.)

The effect can be startlingly beautiful: concave patterns on one side are convex on the other, and vice versa.

One artist who has used this to make some beautiful pieces is Christian Lindow, using equipment at the Plumier Foundation.
