A lathe leveler for centering a cutting tool in relation to a cylindrical work piece includes a first leveling arm having a first contact point disposed adjacent a distal end of the first leveling arm, a second leveling arm having a second contact point disposed adjacent a distal end of the second leveling arm, a leveling gage, and a leveling plate having a cutting tool receiving surface positioned parallel to a horizontal axis of the leveling gage and on a same plane as a midpoint of the first contact point and the second contact point. The leveling arms and leveling plate are dimensioned and configured such that the cutting tool receiving surface is centered in relation to the work piece when the first and second contact points are in contact with one of the inner surface and outer surface of the cylindrical work piece and the leveling gage is centered.

One embodiment includes display device configured to wirelessly receive a first position status from a positioning device; display a first work-tool working-axis leveling status based on the first position status; receive cut parameters; receive a cut-start indication; determine a first work-tool position status difference based on cut parameters and a second position status; present a position status correction indicator; determine that a third position status is within cut parameters; send a cut-start signal to the positioning device operable to actuate the first work-tool; determine a work-tool cut completion; and send a cut-end signal to the positioning device operable to de-actuate the first work-tool.

A height-setting tool is provided that includes a first clamping jaw, a second clamping jaw, an adjustment member, and an indicator member. The first clamping jaw includes a first clamping surface. The second clamping jaw is opposed to the first clamping jaw, and includes a second clamping surface. The first and second clamping jaws are configured to grasp a jaw of a chuck. The adjustment member is coupled to the first clamping jaw and second clamping jaw, and is configured such that a movement of the adjustment member moves the first and second clamping jaws by corresponding amounts in opposite directions. The indicator member includes an indicator surface. The indicator member is coupled to the adjustment member with the indicator surface equidistant from the first and second surfaces along a clamping direction.

A multi-purpose layout tool and drill guide, and related components and accessories, including a mounting L bracket, laser, swivels stand, headband and lamp.

A method and apparatus for center height alignment of a boring bar is disclosed. The apparatus includes a seat member with a bottom and a back, and a digital angle gauge mounted to the seat member. The method includes the steps of: assembling an apparatus comprising a seat member and a digital angle gauge; calibrating the apparatus such that a Display of the digital angle gauge reads zero degrees; and aligning the center height of the boring bar by rotating the boring bar such that the Display of the digital angle gauge reads zero degrees when the apparatus is mounted onto the boring bar.
