Had a sudden unpaid tree removal job of the "for a friend´s friend" kind. From a few simle cuts to make a bench to accompany a fireplace it turned out into 3/4 day of cutting through 25-30" burly semi-double willow, partially torn over two steel fence posts, with a lot of torque in it. It fell just in the morning, no one of us knew about it. It efectively blocked the only patch, crushing fences and neighbor´s garden tool shed (as well as few nice garden trees). Had a Jonsered 2041 15" B&C with me, because originaly noting more (for the bench) was needed. In some ways I´m glad, because havin´ bigger saw when using 1" ratchet strap as a temporary harness or having no harness at all with 15" under the butt (no caulks) would be pretty uncomfortable. Well, some fun while sometimes tricky cutting, some good movement on fresh air, nice weather-nothing to complain until here (except I´more a hardwood guy and got pinched twice because of the realy soft wood, while once quite in a vain).
The willow was partially to all hollow, with red cube rot and ants over 30´ up the trunk and branches. Of course it was saping as hell to get rid of both. Went from bio-deg bar oil to straight trans oil, but in the end the chain (full-chisel) was looking just a bit better than muddy piece of clothestring with pieces of tuna-can here and there emerging from it. Four days of soaking in gas and petroleum, three sessions with brass wire brush, pint of petroleum, two pints of gas, well over two hours of f****ng around it to salvage almost new chain (well, not so new now because of piece of tie-wire in the wood which also managed to throw the chain, but still over 75% of life in it). Had to make almost complete dismount of the saw to clean it-the red cube rot powder saturated by the sap and poor ants is sticky as hell after few hours of curing on the air. Ruined two evening programs for me.
Here can be seen why the tree removal jobs seems too pricy for a lot of people. These afterparties of the job are never seen by the customer.
