A huge leaning pine is trying to push over my shop and has trapped my travel trailer. Because of the danger to the shop and trailer, removal estimate was many thousands of $, no doubt worth every penny. Though 74 years old I am determined to do this myself, not because I intend to become a professional arborist, but because I cannot afford to have it done and because of my concern for my 1967 Silver Streak trailer which, while no cherry, I wish to protect. My plan is to purchase the equipment I need, mostly used, and resell it when I have finished in order to recoup most of my expenses. To that end I have purchased a Weaver Cougar saddle (no plan to add spurs), a 4:1 tackle for my bosun's chair, various carabiners and webbing straps, a 28' extension ladder, a small pruning saw, a throw bag & line, a Harbor Freight electric pole saw. Years ago I had purchased a new Poulan Pro 18" electric chainsaw to remove from this very tree huge limbs which were damaging the shop roof and whose weight was threatening to pull the tree down, perhaps a pickup truck load of firewood, besides the branches. Also already owned chaps, a manual pole saw, lopping shears, manual chainsaw sharpener, various high capacity snatch blocks and braided lines (from my sailboats), along with the bosun's chair. My electric chainsaw is pretty heavy and awkward for climbing, and so I thought I might pickup a Stihl ms201 top handle to give me a slight edge. (I have posted an inquiry in the 201 modification thread) As it is, I can only work for short periods before tiring to a limit beyond which I don't feel it would be safe to continue. I am a boat builder, with knowledge in operating tools, machinery, even heavy equipment. Though I am slightly handicapped, having fractured my pelvis, both ankles and wrists, and suffer from arthritis. Attached are photos of the tree, which is about 50' tall and has a girth of close to 3' at its base. I am leaving those branches til last that protect the trailer from falling stuff; there is fortunately quite a network of them, which I have attempted to photograph. Also I have placed some plywood on top of the trailer to further protect it. Most of you will figure, no doubt rightly, that I am a dxxxxd dangerous old fool for attempting to do this, especially with no one else to help. I admit it even sounds foolhardy to me, and a challenge in the greatest extreme. But I am determined to take this to its conclusion, or as far as I can, because I really have no choice. It would be extremely kind of some of you experienced guys to offer advice, even when it appears I have my own reasons to take it or not. That will be sincerely appreciated. And all comments are welcome.
