Straight-line Chuck

Historical Straightline Chuck

A Straightline Chuck is used to hold objects vertically, and allow for ornamenting them that way. The object being held:

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

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.
