this should be a good tread. lots of information out there.
myself, i started cutting firewood at 13, felling at 14,climbing at 16. obtained education in high angle work and moved on to obtain education in logging and clearing. educated in portions of silviculture, learning to cruise and estimate standing timber value and forest management. educated in scaling and grade. became the instructor for Woods And Chainsaw Safety.
i test just about everything to do with chainsaws for homeowners,loggers,arborists and lumberjacks.
