Dome Chuck

Historical Dome Chuck

A Dome Chuck (sometimes called a Spherical Chuck) is used for holding the object perpendicular to the axis of rotation (or at some other angle which is not aligned with the axis of rotation).

If you want to buy one, Lindow Machine Works makes a very nice one. But, if you would rather make one, Bill Ooms and Jon Magill have some nice designs.

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!


Dome & Oblique Chuck

Bill Ooms made what he calls a Super Dome Chuck, and has published his plans. It is a combination of a dome chuck and an oblique chuck. He has built two very nice ideas into his design:

  1. Use of a digital protractor for setting the angle, and
  2. Use of a threaded mechanism to set the distance off centre.

Jon Magill made a combination dome chuck, eccentric chuck, and oblique chuck which he showed at the 2016 AAW Symposium in Atlanta. (Images below are courtesy Jon Magill.)
