The local Stihl rep in our area has the Northwests largest personal antique chainsaw collection housed in a huge mansion he built on his property. Started in the woods in his teens, got a saw store going when he was in his early 20's now he is in his late 40's and sold the saw shop and works directly for Stihl. On the side he sets up competition saws for logger rodeos around the World - even for loggers in Sweden. I have seen a 36 inch diameter disk cut off the end of a log in less than 20 seconds using one of his prepped saws. The reason he has done as well as he has is because he opened his store in a little town that was the last stop before the real timber forests start in the foothills of Mt. St. Helens. When a logger had a problem with a saw, he was on the other end of a radio and got him fixed up pronto pup. Service with a smile and a good saw line made the guy a ton of money. We still have old growth getting cut around here but there aren't many mills that can handle a log truck with a one log load. Most debarkers, bucking lines and primary breakdown saws just can't handle a log 8 - 9 feet in diameter. . . Most of the tree fallers I know now have a Stihl over their shoulder and bicepts about 30 inches around. . . a lot of fun to watch them work.
