Pinblock drilling rig

[William Monroe]

Hi Fred,

To add to what Ron said, there are no channels for air.  With this rig, 
there is no problem getting enough float to move the rig easily.  The bigger 
problem is getting too much float.  The trick is finding the pressure that 
floats the device smoothly, but with enough friction to allow you to control 
the positioning of the rig.  As the bit begins to get close to your center 
punched hole in the pinblock, you don't want the rig acting like a greased 
pig.  Once you get the hang of it (about 1/3 or less of a block) it's pretty 
slick......

I don't know, Ron, It's starting to look like you should patent the 
Ronocraft........   ;-]
