I had an acquaintance a while back, good man, tell me that when he had built himself a cherry picker for his truck to grab and load logs, he tacked it all together. Then he had a friend who was a good welder go through and weld it. He told me that he could weld, but he wasn't going to depend on his skills loading logs with it. I had to admire his common sense. He was a handy person- had a backhoe mounted on the back of an old truck cab. He had put a 4 cylinder car engine in an old tractor, transmission and all. He knew what he was doing. He took risks, but they were calculated - not from ignorance or overconfidence.
