Spherical Slide
Just getting started?
You can delay getting one of these. Frankly, unless you have the need for one, you could make a load of stuff never having one of these. But, they can be used to make some really cool stuff!



Lathe Axes

A Spherical Slide is used to make a controlled, curved surface. It is a modified Cross Slide, and is different from a Curvilinear Slide / Apparatus:

  • Spherical Slide - the cutting frame is rotated around a vertical "line" which is parallel to the Y axis.
  • Curvilinear Slide - the cutting frame is moved in an out (in the direction of the X axis) whilst moving along the Z axis.

Fundamentally, this works the same way a sphere-cutting jig does.

The video below was given by Peter Gerstel at the 2018 Ornamental Turners International Symposium. It shows his approach which was used to make a dome shape to the end of an object.


The second video, below, was given by Jon Magill at the 2018 Ornamental Turners International Symposium. It shows his approach to making organic curves with ornamental turning. But, what is most intriguing about his approach is the overlay used to allow the ornamental turner to see what the cut will be.
