I HAVE SANDSTONE AT 4-1/2 FEET. I SACRIFICED A $6.50 DRILL BIT FOR EACH
GROUND ROD. USING A FRICTION SAW OR A THIN GRINDING DISC, CUT THE DRILL
BIT IN TWO AN INCH BELOW THE HEX SHAPED END THAT FITS INTO AN IMPACT
DRILL, ALSO KNOWN AS A ROTARY HAMMER DRILL. AFTER GRINDING A BEVEL ON
EACH END OF THE GROUND ROD, AND ON THE TWO ENDS OF THE DRILL BIT WHERE
THEY WERE SEVERED, WELD THE CARBIDE TIPPED, FLUTED DRILL BIT HALF ON ONE
END AND THE HEX SHAPED HALF TO THE OTHER. WHAT YOU HAVE NOW IS AN 8 FOOT
LONG DRILL BIT. AFTER SINKING THE ROD,(MY SANDSTONE WAS TWO FEET THICK)
DONT WORRY ABOUT CUTTING THE HEX OFF. MAKE YOUR CONNECTION ON THE COPPER
CLADDING OF THE ROD. THE HEX IS CERTAINLY NOT AS SHARP AS THE MUSHROOMED
HEAD OF A HAMMERED ROD.
