I have been thinking about that lately. Someone I talked to along the way said (forgot who, and I do apologize) that I need to incorporate a backflow device into the drill stem near the bottom. Would you think that should be included in the adapter while I am making the hole for the mud fluid?
From what I found on the internet, its called a Kelly valve or backflow prevention valve. There are no indications of Artisian wells around here, but it might be a good idea? Not sure though.
Thanks to my Grandfather, I have his Atlas Metal lathe along with boxes of bits and related tools to help with this project. The last time I used a metal lathe was in high school some 30 years ago. Might just have to ask some friends from Boeing to assist with the lathe.
