Abstract
A woodturning tool for creating containers has a first rigid arm, and a second rigid arm. The first rigid arm has two ends with a cutting blade at the first end. The second rigid arm has two ends with a guiding device at the first end. The cutting blade and the guiding device are operatively aligned. The first and second rigid arms are adapted to move relative to one another.
Claims20
A woodturning tool for creating containers comprising:
- a first rigid arm with two ends having a cutting blade at the first end;
- and
- a second rigid arm with two ends having a guiding device at the first end;
- said first rigid arm being pivotally connected at a first point to said second rigid arm at a second point;
- said first point being between the ends of said first rigid arm;
- said second point being between the two ends of said second rigid arm;
- said cutting blade and said guiding device being operatively aligned;
- and
- said first and second arms being adapted to move relative to one another.

A woodturning tool for creating containers comprising:
- a first rigid arm of a circular cross section having two ends with a cutting blade at the first end and a handle connected by longitudinal knurls at the second end;
- said cutting blade being aligned with the longitudinal axis of the woodturning tool;
- a second rigid arm of a rectangular cross section having two ends with a guiding device at the first end;
- said cutting blade and said guiding device being operatively aligned. said first rigid arm being pivotally connected at a first point between said two ends to said second rigid arm at a second point between said two ends;
- an adjustable screw threaded through said second rigid arm between said second point and the second end adapted to control how close said cutting blade pivots toward said guiding device;
- a first clearance distance in said first rigid arm from approximate said first point to said first end;
- a second clearance distance in said second rigid arm from approximate said second point to said second end;
- and
- an angle of said second rigid arm between said second point and the second end adapted to make said adjustable screw approximately perpendicular with said first rigid arm when said cutting blade and said guiding device being a set width apart.
