I recently cut down a tree for the first time, and though nothing damaged and nobody got hurt, it fell in the exact opposite direction that we wanted it to. Part of the reason this happened was because we decided not to tie a rope to the tree, partly because it was very, very difficult to get the rip UP INTO the tree (by tying a hammer to it, and throwing).
I saw the net gun 'able, and got me thinking, there's got to be a way to launch a single rope, maybe 30' or 40' up, with some sort of weight on the end, into the top of a tree. It would need a weight heavy enough to drop the end of the rope back down to the ground, in order to tie the proper knot on it, to secure the rope to the tree. I suppose fishing line could be used if it's not strong enough to launch rope, and the rope can be tied onto the line and pulled over.
So is there an instructible I should use, or which one should I modify? I have compressed air and proper tools, but I'm not engineering-minded enough to come up with my own (nor do I have the time and money for repeated trial and error).
