Abstract
Adjustable guidebushes and methods for using the same facilitate cutting joint elements into work-pieces to join together two or more of the work-pieces. In some embodiments, the adjustable guidebush includes a guide surface defining a number of outer diameters having different lengths. Positioning different outer diameters of the guide surface to interact with a cutting guide allows one to adjust the fit of the joint elements formed in the work-pieces.
Claims15
A method for cutting a work-piece, comprising:
- (a) securing an adjustable guidebush to a cutting tool, the adjustable guidebush comprising a through-bore for receiving a portion of a cutter of the cutting tool and a guidebush guide surface that extends at least partially around the cutter, wherein:
- (i) a cross-section of the guidebush guide surface comprises at least a first outer diameter and second outer diameter;
- (ii) the first outer diameter is not substantially equal in length to the second outer diameter;
- and
- (iii) the through-bore defines a longitudinal axis and the guidebush guide surface is substantially parallel to the through-bore longitudinal axis;
- (b) at least temporarily positioning a cutting guide with respect to a work-piece;
- and
- (c) making a first cut in the work-piece with the cutter, wherein a first portion of the guidebush guide surface interacts with the cutting guide to guide the first cut,
- wherein the cross-section of the guidebush guide surface is perpendicular to the longitudinal axis of the through-bore.
A method for cutting joint elements in wood work-pieces comprising:
- (a) making a first cut in a work-piece with a rotating cutter by guiding the work-piece relative to the rotating cutter with an adjustable guidebush, the adjustable guidebush comprising:
- (i) a guide member comprising a through-bore that at least partially receives the rotating cutter;
- and an outer guide surface that extends at least partially around the rotating cutter, the outer guide surface slidingly interacting with a cutting guide during the first cut;
- (ii) wherein a cross-section of the outer guide surface comprises at least a first outer diameter and a second outer diameter;
- (iii) wherein the first outer diameter is not substantially equal in length to the second outer diameter;
- and
- (iv) wherein the through-bore defines a longitudinal axis and the outer guide surface is substantially parallel to the through-bore longitudinal axis;
- and
- (b) adjusting the adjustable guidebush by rotating the adjustable guidebush,
- wherein the cross-section of the outer guide surface is approximately perpendicular to the longitudinal axis of the through-bore.
A method for cutting joint elements in wood work-pieces comprising:
- (a) making a first cut in a work-piece with a rotating cutter by guiding the work-piece relative to the rotating cutter with an adjustable guidebush, the adjustable guidebush comprising a tubular guide member having an oval shape cross-section surrounding a portion of the rotating cutter;
- (b) adjusting the adjustable guidebush by rotating the adjustable guidebush,
- wherein the oval shape cross-section of the adjustable guidebush is perpendicular to a rotation axis of the rotating cutter.
