Yard work is constant self-tutoring. The tutor shares an observation from it.
Today I was disassembling some reinforcements made last fall for an abandoned project. The reinforcements were triangular, consisting of landscaping ties and 2×6 boards fastened with lag screws. They had purposely been made heavy and strong.
I began to loosen one of the lag screws; it started to turn with much difficulty. Suddenly, it turned much more easily: I knew it had twisted apart. It didn’t do so at the head; I still had to turn it out. However, only the top inch or so came out, while the bottom remained lodged in the wood.
I didn’t think any of the other lag screws would twist apart; rather, I believed the one that did was defective. When another one twisted apart the same way, I decided to change my method.
The next lag screw I turned slowly through short arcs with pauses in between. It stayed whole, as did the others I so removed.
