1. The combination of:

  • an insert;

    a threaded point for an arrow; and

    an arrow shaft having a cylindrically shaped wall of a predetermined inner and outer diameter disposed about a longitudinal axis on one end thereof, said insert comprising;

    a cylindrical insert body of a first diameter adapted to be disposed in said one end of the arrow shaft;

    an enlarged shoulder means disposed on said one end of said insert body extending from the inner to the outer diameter of said one end of said arrow shaft wall for preventing said insert body from sliding too far into said arrow shaft;

    a first annular alignment ring means disposed on said one end of said insert body adjacent to said enlarged shoulder means, said first alignment ring means having an outer diameter of a size for causing a tight, closed slidable fit when said first alignment ring means is disposed in said one end of the arrow shaft;

    a second annular alignment ring means disposed on the exterior of said insert body at a position spaced at a substantial distance from said first alignment ring means for causing the longitudinal axis of the insert body to be coincident and in alignment with the longitudinal axis of said arrow shaft, the outer diameter of said second alignment ring being larger than said first diameter of the insert body and larger than inner diameter of said arrow shaft and the outer diameter of said first alignment ring being larger than the outer diameter of said second alignment ring and larger than the arrow shaft to form a press fit with said arrow shaft; and

    glue trap means for forming an enclosed space between said first and second alignment ring means, said insert body and the inner wall of the arrow shaft for sealingly holding an adhesive material provided for preventing the insert body from sliding out of said one end of the arrow shaft.
