Drive point is simple but requires steel threaded pipe. Short lengths are needed to add pipe as you go down so you can stand up straight and swing the hammer. Shallow wells are easy enough. Problems occur when going deep and getting out of plumb, hitting hard rock and sticking or breaking the point, sand or rock plugging the opening in the point after reaching water, not knowing how deep the water is you are trying to pump from and running out in hot weather, and running into some large company or neighbors utility line of some kind. Check your local and state laws, purchase any needed permits, have the area checked for utility lines, find out how deep your water is in the area, and get into shape if the well is fairly deep. Last one I helped drive was in the 1970s under my Grannies kitchen sink. 54 feet to water. Took about a day.
