A 1 metre SDS masonry drill helps. To get the old one out a pipe wrench can be useful, and possibly a slide hammer. In the days when I was into putting in earth stakes, I developed a routine that tended to avoid unfortunate happenings - learned the hard way, of course. The idea was to take a 4' solid aluminium-alloy rod, then turn a point at one end and drill and tap a thread at the other for a screw terminal. The next requirement was for a pint or so of soapy water and the most powerful mains-electric drill I could find, and then secure the terminal end of the rod in the chuck. Locate the spot where the earth stake was to go, and scoop a small 'funnel' out of the earth, into which the soapy water was poured. The point of the rod was then placed in the centre of the funnel, the drill started, and using only minimal pressure and a fairly low drill speed, press the rod into the ground. Sometimes the rod would go in to the right depth, and sometimes it would hit a solid obstruction. In the latter case it was important to keep the drill rotating while easing the rod back out of the soil and then repeating the process close by until the desired result was obtained. Thanks, muchly. But needs to be a pretty big lathe to turn a 4 ft rod. Merely the usual hollow shaft through the headstock holding the chuck, and 4 ft of space behind the headstock. (Or a temporary hole in the wall if necessary!) That's a neat idea; must try that! |
