I guess so. I have a Hayne’s manual that is dog-eared, oil-stained, and in pretty rough shape. But it got me through many Saturday morning sessions under the hood of my old vehicle.
I’ve done such things as deck building and repair, all kinds of roofing, painting, simple plumbing and electrical work (as a kid, I ran a power line to my treehouse, and had it electrically lit), and general carpentry and metal work. I can handle all kinds of power tools, as well as the old fashioned manual tools that sometimes do the job better/finer/more exactly. I got to the point where I was asked to write a monthly DIY column in a local “house and garden” kind of magazine. I did, and had a great time doing it, since it often involved interviewing local tradespeople. Great chance to learn more.
I never did anything professionally in any case. I just like being a DIYer. My Dad loved DIY stuff, so I guess I get my interest and skills from him.
