Straightline Chuck


Historical Straightline Chuck

A Straightline Chuck is used to hold objects so they don't rotate; rather using the spindle's vertical rotation to move the object vertically, and allow for ornamenting them that way. The object being held:

  • moves up and down (along the Y axis), and
  • rocks back and forth (the X axis), but
  • does not rotate around the lathe's spindle drive axis (the Z axis).

Current-day ones are commonly built with an oblique chuck integrated into the device. This is particularly useful when making ornamentation on cylinders like pens, or on long, flat objects like bracelets.

Lindow Machine Works makes a very nice one that has even been used on an MDF rose engine lathe.
