Dowel centering kit
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to dowel apparatus, and more particularly pertains to a new and improved dowel centering kit wherein the same is arranged for imparting an indicator recess within a coaxial center of a dowel rod for a subsequent turning procedure. 
     2. Description of the Prior Art 
     In various woodworking procedures and the like, dowel rods are frequently positioned within a lathe or other machine tool for turning and other woodworking procedures. To provide proper orientation within a tail stock and the like of a turning machine, the dowel rod must have a center indicated on an end of the dowel rod directed into the tail stock. 
     Various gauge structure utilized in the prior art for centering devices are typified in U.S. Pat. No. 4,280,279 to Grundfest wherein an alignment tool is arranged for aligning conductors of various multi-conductor cables.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 10 thereof, a new and improved dowel centering kit embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the dowel centering kit 10 of the instant invention essentially comprises a mounting block 11 defined by a mounting block top wall 12 spaced from a mounting block bottom wall 13. A mounting block first end 14 is spaced from a mounting block second end 15, wherein the mounting block is defined by a parallelepiped configuration. A row of axially parallel first bores are spaced apart between the block first end 14 and the block second end 15. The first bores 16 are of sequentially increasing diameter from the block first end 14 relative to the block second end 15. The bores 16 are further projected interiorly of the mounting block 11, with each bore axis orthogonally oriented relative to the top wall 12 projecting downwardly from the top wall 12. A plurality of second bores 17 each of an equal second bore diameter, are aligned with a plurality of first bores. The second bores are defined by a second bore length. A series of third bores 18 are of a predetermined third bore length and a third bore diameter, and wherein the third bores are coaxially aligned with remaining first bores, wherein the second bores and third bores are projected orthogonally into the mounting block from the bottom wall 13. 
     A spike member 19 is provided in cooperation with a cap member 20. Each spike member 19 is defined by spike member cylindrical collar 21 defined by a diameter substantially equal to the second bore diameter, including a spike projection 22 coaxially mounted to the top surface of the spike member cylindrical collar 21. A spike member support cylindrical base 23 defined by a predetermined diameter substantially equal to the third bore diameter is provided and defined by a cylindrical base length substantially equal to the third bore length. Each second bore length is substantially equal to a spacing or spike length from a top surface of the spike member cylindrical collar 21 to a bottom surface of the spike member support base 23. In this manner, the first bores 16 are arranged to receive dowels of varying diameters, wherein a plurality of the first bores 16 adjacent the first end 14 are of insufficient diameter to receive the collars 21, whereupon the collars 21 are directed into the second bores 17, as illustrated in FIG. 2, wherein the spike projection 22 projects into the first bores associated with the second bores for positioning of a lower terminal end of a dowel rod, in a manner as illustrated in FIG. 10. The cylindrical cap member 20 is provided defining a cylindrical skirt and a top planar web to receive an upper terminal end of an associated dowel rod &#34;D&#34; to accommodate a hammer 24 striking the cap member 20 to minimize splitting of the dowel rod when struck by the hammer 24. 
     The kit construction, as illustrated in FIG. 6, includes a second mounting block 25 defining a second block top wall 26, including a row of rigid cylindrical boss members 27 of varying diameters to receive a set of cap members 20 thereon. The cap members 20 are also of varying diameters and are of the varying diameters to accommodate varying external diameters of the dowel rods &#34;D&#34; utilized. 
     FIG. 8 illustrates a modified spike member 30 positioned within a third mounting block 28 within one of the mounting block bores 29 accommodating the modified spike member 30 and the spike member 19 therein. The modified spike member 30 includes a tubular collar 31, including a tubular collar bore directed therethrough. A cylindrical base 32 is provided with a cylindrical base extension 33 received through a lower terminal end of the tubular collar bore 31a, wherein a spring member 43 is captured between an upper terminal end of the cylindrical base extension 33 and the recess within a lower portion of the tubular collar 31. The cylindrical base extension 33 mounts the extension rod 34 coaxially thereof extending upwardly to mount a piston 35 at an upper terminal end thereof. The piston 35 projects sealingly within a fluid reservoir 39 formed within a cylindrical collar central bore 40 of an associated cylindrical collar 36. A conical projection 37 is mounted coaxially of the cylindrical collar 36 and the tubular collar 31, whereupon impact of a dowel rod upon the upper terminal end of the conical projection 37 directs a fluid through a conduit 38 directed coaxially of the conduit projection 37 to impart an indicator die onto an axial center of an associated dowel rod, as well as imparting an indentation within the dowel rod by impact of the hammer 10 upon the dowel rod &#34;D&#34;, as illustrated in FIG. 10, when the modified spike member 30 is positioned within one of the first bores 16 and the tubular collar 31 is directed into a third bore 18. The block 11, the use of the second mounting block 25, and the third mounting block 28 are mounted fixedly within a base container 41, with a lid 42 pivotally mounted thereon to secure the various components of the kit structure for storage and transport thereof. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
