In another post I mentioned that my son, Jake, had an opportunity to 'earn' some free turning wood in exchange for some table saw work which included ripping several pieces right down the middle and then cutting some thin (5/16ths) strips of poplar.
Since Jake wasn't much for TS work he asked how we were going to adjust the fence precise enough to make consistent cuts for Jim (his customer). I explained to him that recently in our magazines there has been a lot of chatter centered around thin strip ripping jigs and explained how they worked. mind you, I already had in mind how we were going to do this but watching the wheels turn in that boys brain is a really cool thing to behold!
During our conversation about what was needed Jim and my father-in-law, Ray were also in the garage and when I presented the idea of the jig they both had that look that told me they were going to start searching my shop for the wood and other components to build one but, Jake who looked right at me asked, "Dad, why can't we just use the combination square?" "Why, what on Earth do you mean, my young padawan," I asked.
He replied (and gave me goose bumps), "If we take the combination square, place it in the far miter slot and push the ruler up to the left facing tooth of the blade and then back it off 5/16ths of an inch, and then before each cut adjust the fence with the wood in place up against the ruler, won't that do the same thing?" Brought a tear to me eye!
Truly, he must take after his mother because I'm about as smart as a bag of hair.
