Abstract
A dowel cutting method and apparatus comprising a stationary cutting tool having an internal bore and at least one cutting edge at its input end into which woodstock is disposed while being rotated by an electric hand drill or the like to create a finished dowel at the opposite end of the cutting tool. The cutting tool may be held in a bench vise. A sizer for dowels is also disclosed comprising a series of holes in a flat metal plate having a ground side which cuts down a dowel in a sequence of operations, if needed, to an accurate smaller dowel. A simple final sanding operation is also disclosed utilizing sandpaper and the sizing apparatus.
Claims14
A dowel cutter apparatus comprising
- a rotatable chuck;
- means for rotating said chuck;
- means for holding a length of woodstock in said chuck to be rotatable with said chuck;
- A cylindrical cutting tool having a cylindrical inner surface, a cylindrical outer surface, an inside diameter, an input end having at least one cutting edge disposed along said inside diameter, an output end spaced apart from said input end, and at least one planar face extending from said cutting edge on said inner surface to said outer surface, forming an angle with a line parallel to said axis, and intersecting said edge;
- means for holding said tool in a stationary position;
- wherein said woodstock is rotated by said chuck and inserted axially into said tool at said cutting edge to form a length of dowel.
A sizer for accurately varying the diameter of a dowel comprising
- a plurality of cutting tools disposed on a flat plate;
- means for holding said plate in a stationary position;
- and
- means for rotating said dowel;
- wherein said dowel is directed axially into selected of said cutting tools to accurately cut a dowel to a desired diameter.
A sizing tool for accurately varying the outside diameter of a dowel comprising a metal plate having a series of various sized circular holes and being ground on one side of said plate, means for holding said plate in a stationary position, and means for rotating a wooden dowel about its longitudinal axis, wherein said rotating dowel is directed axially into one of said holes through said one side of said plate to size the dowel to a selected outside diameter.
