Abstract
A method, device, and system is described herein for pointing a rotary drill bit. A rotary bit pointing device is positioned between a proximal end of a control shaft and a universal joint. As the bottom hole assembly rotates, various portions of the rotary bit pointing device are enabled and subsequently disabled to apply a substantially constant force in a substantially constant direction to the control shaft. Such a force causes the distal end of the control shaft to point the rotary drill bit in a target direction.
