Abstract: An adjustable spacer tool for spacing balusters includes an extendable pantograpic assembly having a first and second end and including evenly-spaced parallel uprights and X-shaped sets of cross-bars pivotally connected to one another. Each X-shaped set is pivotally connected to a pair of uprights adjacent upper ends thereof and pivotally and slidably connected to the uprights adjacent lower ends thereof. An arm, finger and cam extend outwardly from each end of the assembly to provide spacing between each end of the assembly and a desired surface for various sets of same-width balusters. Each arm is pivotally connected to one end of the assembly and to one end of the finger. The other end of the finger is pivotally and slidably connected to a respective end of the assembly. Each cam is pivotally connected to the arm distal the assembly. Removable connections permit adjustment of the overall length of the tool and replacement of parts.

Abstract: A method of manufacturing a staircase handrail volute, comprising the steps of: (a) cutting a workpiece from wood with a bandsaw such that the workpiece has an approximation of a shape of the volute, wherein the approximation dimensions are larger than the shape dimensions; (b) mounting the workpiece so that the workpiece may be operated on by a numerically controlled machine tool; (c) cutting a bottom surface of the workpiece to the shape dimensions with the machine tool; (d) cutting lower side surfaces of the workpiece with the machine tool to a first dimension between the approximation dimensions and the shape dimensions; (e) cutting the lower side surfaces of the workpiece with the machine tool to the shape dimensions; (f) drilling at least one mounting hole in the bottom surface with the machine tool, the at least one mounting hole for holding the workpiece in steps (g) through (j); (g) turning the workpiece over and mounting the workpiece so that the workpiece may be operated on by a numerically control

Abstract: A hand held scraping tool for scraping across a work surface includes an elongate handle and a mounting body connected to a distal extremity of said handle by an arched neck member. The mounting body includes a substantially planer mounting surface with at least one positioning peg and a male threaded mounting screw extending axially outward therefrom. A scraping blade is placed against the mounting surface such that the positioning peg and mounting screw pass through apertures formed in said scraping blade to retain said scraping blade in a seated position. The scraping blade includes a plurality of scraping edges. A locking collar having a centrally located, female threaded hole therein screws onto the mounting screw to thereby sandwich the scraping blade between the mounting surface and said locking collar and thus retain the scraping blade in a secured position.

Abstract: An apparatus for selectively and hydraulically locking a hollow cylinder body, such as a lathe cylinder body, onto, and unlocking the cylinder body from, a cylindrical shaft includes a tubular sleeve defining an axially extending passage therein, the sleeve including a centrally located exterior annular channel. The hollow body includes an axially extending cylindrical passage and a single female threaded bore formed to extend radially through the hollow cylinder body to bisect the axial passage thereof. The sleeve is inserted and fixed within the axially extending passage of the body so that the annular channel faces and is closed off by the walls of the axially extending passage to thereby form an annular cavity which is in fluidic communication with the female threaded bore.

Abstract: A measuring tool for measuring and marking a generally straight distance between opposing boundaries comprises an elongate shaft which is selectively extendable to span a range of distances. A measuring scale is formed in the shaft for indicating the length spanned by the shaft, and a cockable/releasable pointed tip is disposed on an extremity of the tool for making indentation markings on a surface to be marked. A screw and corresponding measuring scale for specifying a depth of penetration of the baluster into a handrail or stair tread for inclusion in the length indicated are also available in a preferred embodiment.

Abstract: Improved methods of fabricating at least partially curved staircases include a first method in which preformed step structures have treads with curved slots formed in the underside of the ends which define a path for insertion of top edge segments of thin starter strips. The slots are collectively configured to laterally deflect the inserted starter strips in a manner longitudinally conforming them to at least partially curved paths of the overall stringer structures in the completed staircase. The stringers are then laterally built up and completed by securing reinforcing structures to the side surfaces of the laterally deflected strips. A second method uses preformed cooperating treads and risers themselves as a form which defines an at least partially curved path for the stringers.
