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

The Mast

LS100 Mast

Shuttle & Winch

The shuttle is driven by chain attached to a two speed hand winch that provides both hoisting and pull down capabilities. The winch includes a handbrake which is used when the winch ratchet lock is released to lower the rotary.

Rotary Mount

The rotary mount accommodates an engine-driven post hole digger. The throttle is modified to control engine speed.

Rotary Mount

Rotary Mount - Hinge

The rotary mount is hinged to the shuttle so that the rotary can be swung away to either side to enable well casing to be installed 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.


LS100 Swivel

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.

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.


LS100 Slips

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.

LS100 Inventory

Prior to leaving for a drill site, it is important to carefully examine the checklist to ensure that you have all the items necessary to finish the job. When drilling hours from your home base, you may not be able to return home to pick-up a missing coupling, an extra drill bit or a replacement swivel seal!
