I'm pretty much self taught for all my outdoorsy and/or tool stuff. My father didn't have a good grasp of the physical world. He was smart, but for some reason the third dimension eluded him. After he died, I'd run into one of his repairs, and just shake my head. It sorta worked after a fashion, but there was an obvious(to me) repair that would have been just as easy, and much better. He took up woodworking after he retired. He was terrible at it, but he gave it hell, and enjoyed it.
Anyway, the point is... Was there a point? I think there was a point... Oh, yea, I tend to avoid machines that can F me up. That's one of the reasons I got into chainsaws late. That, and I'm generally inclined to use manual tools. I have a table saw from my father. Never turned it on. I also have a planer, and a bandsaw that needs fixing, but will never be fixed by me. I've gotten comfortable with a chainsaw, and if a job can't be handled with that or a handsaw, I don't usually do it.
