Between bouts of drilling (it took a really, really long time), we let the drill sit to let the right-angle adapter cool off. See, its casing is made of plastic. Yep, plastic. Which melts when the gears and bushings inside get hot. As they do when one is drilling hardened steel.
Those "breaks" consisted of cutting down four trees in the back yard as well as a lot of small trees, bushes, and other crap crowding the yard. Then of course we had to chop up the tree trunks and branches to make them small enough for the city (or friends: Hello! Firewood!) to remove. I wish we had photos. Matt held a rope which terminated in a grappling hook wrapped around the tree trunk, half way up, which I attached by climbing a ladder and hooking it in place. Then he applied pressure to pull the tree in the correct direction while I notched the trunk with my chainsaw. See, the safe fall-way lay between the fence and my garage is pretty narrow, and if the tree fell even 10° in the wrong direction... crunch!
But all went well! Now I have a giant pile of tree-pieces in the alley behind the house. Need to log off now and run downtown. I owe Matt dinner and several beers!
Best,
Chris
