Hello all, I have most parts needed for drilling my own well. Most wells in my area are in the 130 foot depth range. Most small drilling rigs use 5' lengths of pipe for drill stem. I already have a lot of 1" id and 1.312 od of NPT threaded pipe. The problem I foresee is the failure of the drill stem due to the npt threading, or the inability of freeing the joints at withdrawal. I cannot baby the rig in a way to avoid the stress on the stem and joint couplings. I am thinking of making box and pin ends to place on the end of each pipe section and weld them on. What thread type would you use in this endeavor. I have viewed mayhew jr, and other types, but don't really know what might be best. It must have strength, the ability to uncouple sections after use and easy on a guy who hasn't threaded on my Hendey Lathe in 30 years. She is a 14" x 102" with taper attachment, etc.
Ideas? Thanks, Don
