Abstract
A drive shaft assembly for a portable lathe includes a first hollow shaft and a second shaft axially aligned with and telescopingly received in the first shaft, for permitting an effective length of the drive shaft to be altered within a limited range. The first and second shafts are also rotatable relative to each other. Opposite ends of the first and second shafts have uncovered joints including mounting flanges attached thereto, and a locking device is provided to lock both first and second shafts relative to each other after they have been adjusted to a desired axial and rotational orientation.

In a portable lathe, a drive shaft assembly connectable between a workpiece and a lathe headstock, the drive shaft assembly comprising a first hollow shaft;
- a second shaft axially aligned with and telescopingly received in said first shaft, for permitting an effective axial length of said drive shaft assembly to be altered within a limited range;
- said first and second shafts also being rotatable relative to each other;
- opposite ends of said first and second shafts having mounting flanges attached thereto;
- and a locking device effective to lock said first shaft to said second shaft after said first and second shafts are axially and rotationally oriented relative to each other.
