The Baptist Drilling Method is a method of borehole construction that utilizes a valve incorporated into the bit at the bottom of the drill stem to maintain pressure during the drilling process. The main action that is used for power is a rope and pulley system.

Depends on rate of drilling
The Baptist Drilling Method utilizes a rope and pulley system to jettison a 1.25 inch drill bit into the ground again and again. Similar to sludging style drilling, this technique works to bore the hole with repeated contact into the ground.
Technical support can be found in open-source manual
All components of the drilling rig will need to be replaced over time with wear and tear
The lifecycle of this drilling rig depends on how well constructed and maintained the materials are
Manufacturer Specified Performance Parameters
