ABSTRACT:
Bulk arrow shafts, of various diameters, obtained from a manufacturer, which are tapered on one end and square cut at the other end, are subsequently securely supported, accurately measured for an arrow length wanted by an archer, and then cut to this measured length by an archer, who uses this portable bulk arrow shaft guide, support, measurement and guided miter-like razor saw cutoff assembly. An elongated planar base of this assembly is made to rest on a work table or on another level surface structure. A top opening central dovetail groove extends throughout the length of this base. A slidably, selectably positioned receiver subassembly, having depending complementary dovetail portions, is removably interfitted with this base, at the measuring end thereof, to hold a tapered end of a bulk arrow shaft at a designated length of the final arrow shaft length. This receiver has oppositely positioned integral pointers to designate the selected length of the arrow shaft that is wanted, in respect both to an inch scale, and to a centimeter scale, i.e. an English and a metric scale, which are on opposite sides of this base. When the receiver is located at the correct length position, a thumb screw, carried by the receiver, is rotated to create a tight fit between the interfitting dovetail portions. At the cutoff length end of this base, an arrow shaft guiding, encompassing, and gripping, Vee block clamp subassembly, having a thumb screw and also having depending complementary dovetail portions, is initially slidably placed and then securely positioned on the base to so remain by using set screws. This subassembly is also formed to include a transverse guiding vertical slot arranged perpendicularly to the longitudinal axis of the base, to slidably receive and to guide a razor saw to be used in cutting the bulk arrow shaft, to create an arrow shaft having the length selected by an archer in respect to her or his sized archery bow and in respect to her or his draw length.
