Henniker Directional Drilling (HDD) was asked by the Appalachian Mountain Club of New Hampshire to drill a hole up the center of a cut 40’ foot Pine Tree to
make provisions of a way to stand their tree back up.
HDD bored a hole 7 ½” feet into the tree for a custom built steel sleeve to be inserted and allow the tree to stand upright.
Henniker Directional Drilling was able to accomplish this by evaluating the tree and finding the best centerline. Then we positioned the tree level on the proposed
centerline to drill and square to our boring machine .This enabled the tree to be anchored down to our drill. Jeff Martin then fabricated and mounted a centralizer to the
bottom of the tree to align our drill and mount the tree. HDD built a 10 ¾” custom drill bit for the purpose of creating a hole into the tree. Jeff then began to slowly
rotate and feed the bit in to base of tree. Air pressure from a portable compressor was used to feed through the drill bit and clear out cuttings. The HDD crew was then
able to successfully drill a hole 7 1/2' feet up tree allowing a custom built steel structure to be inserted in to allow tree to be stood back up and safely supported.
