Abstract
The present invention consists of a lathe attachment for installation on a portable bandsaw mill, for turning round shafts from wood blocks on the portable bandsaw mill. The lathe attachment has an elongated chassis, a tailstock and a headstock mounted on opposite ends of the chassis for holding and rotating a wood block along the chassis. Bindings are provided to retain the chassis to the cross beams of the portable bandsaw mill. In another aspect of the invention, a number of symmetrical facets are firstly sawed along the wood block prior to turning the wood block. The turning of a round shaft on the bandsaw mill is preferably effected while the alignment of the wood block or shaft makes an acute angle with the direction of movement of the bandsaw head.

A lathe attachment for installation on a portable bandsaw mill, for turning round shafts on said portable bandsaw mill, said lathe attachment comprising:
- an elongated chassis;
- a tailstock and a headstock mounted on opposite ends of said elongated chassis and having means for holding and rotating a wood block along said elongated chassis, and
- means for retaining said elongated chassis to the cross beams of a portable bandsaw mill;
- such that a wood block is workable into a round shaft using said portable bandsaw mill.
In combination, a portable bandsaw mill and a lathe attachment mounted on said portable bandsaw mill,
- said portable bandsaw mill comprising a longitudinal bed, a horizontal bandsaw head movably mounted to said bed for movement along said bed, and a plurality of spaced-apart cross beams extending across said bed;
- said lathe attachment comprising a longitudinal chassis, a tailstock and a headstock mounted on opposite ends of said chassis, and means for holding and rotating a wood block along said chassis, and
- means for retaining said lathe attachment to said cross beams of said bandsaw mill;
- such that round shafts are manufacturable on said lathe attachment and said bandsaw mill.
A method for turning a round shaft on a bandsaw mill, comprising the steps of:
- using a bandsaw blade, sawing a number of symmetrical facets along an elongated wood block at a same diameter on said elongated wood block, and enclosing a circumference of said elongated wood block with said symmetrical facets;
- while operating said bandsaw blade in a first direction, rotating said elongated wood block about a longitudinal axis thereof in a second direction opposite said first direction;
- and
- moving said bandsaw blade along said elongated wood block, at said diameter on said elongated wood block for turning said elongated wood block into a round shaft having said diameter.
