Mast
The mast is self contained, detachable from the base and contains a traveling
shuttle which raises and lowers the attached rotary mount. |

Shuttle & Winch
The shuttle is driven by chain attached to a two speed reversing hand winch.
The winch provides both hoisting and pull down capabilities (to improve the cutting action of
the bit).
The winch comes equipped with a handbrake which is used when the
winch ratchet lock is released to lower the rotary. |

Rotary Mount
The rotary mount accommodates a conventional engine-driven post hole digger. The throttle is
modified to control engine speed. |

Rotary Mount - Hinge
The rotary mount is hinged to the shuttle so that the rotary can be swung away to
either side. This provides the necessary area to install well casing without removing the rig
from over the hole. Quick removal of the rotary also allows for hand portability. |

The Swivel & Quill
The swivel and quill connect the drill pipe to the rotary power
unit, allowing drilling fluid to pass through the swivel, into the quill and down the drill pipe
to the bit.
The side-entry swivel assembly was simplified by replacing bearings with low cost seals that are
readily accessible for greasing. The swivel housing is secured by an adjustable support rod and
clamp so seals ride at the proper surface of the quill. |

The Quill
A partially hollow and perforated quill couples the output drive to the rotary drill pipe. The
quill is equipped with a hex nut the same size as the compression caps allowing the use of a
special spanner wrench to unthread the quill from the drill pipe. |

3-Way Valve
The 3 way valve, conveniently located on the
mast, provides quick access for directing drilling fluid to the borehole or back to the mud pit.
This is very useful when connecting new lengths of drill pipe or when loss of
circulation occurs. |

Slips
The table base
is equipped with a slip which provides an easy way to quickly and conveniently support drill pipe
while it is being threaded and unthreaded from the rotary. Slips can also be
provided to support well casing in the hole while additional lengths are being glued-on. |

Drill Pipe
The machine will accommodate a lightweight drill pipe for air or mud rotary
drilling, auger, or with the use of air hammer percussion tools with a break-out system. |
