To me, an invention is an idea turned into something that improves life.
Not all Invention is Innovation
I am way past habitué to "reinvent" or to find "my inventions" already for sale, mutatis mutandis, to adopt/adapt/hack other people's ideas, re-creating their invention...
So, here I am with tree branches that need trimming. As is wont to happen with old trees, some of those branches are really too high to reach with conventional tools.The Itch
This week, I really had to do something about these branches. What about tying chainsaw chain to ropes?
Years ago my Dad had this "backpocket saw", which was a serrated wire with two handles (sort of like this one). It eventually rusted and broke, but using it must have left in my brain the concept that a flexible saw-thing was possible. Eventually a couple years ago I came upon this "chainsaw in a can". Didn't quite convince me.
As-seen-on-the-Internet "survival saws" look and fell not much better than gadget toys.
Scratching the Itch
For real man's work I needed a piece of real chainsaw. In Uruguay I could buy chainsaw chain "by the yard", so I looked for that product here. No luck.
A few stores (Lowe's, Home Depot, Sears) had ready-made replacement chain loops for chainsaws. I knew I could cut a link, and end up with a nice bit of chain that way. Having some outstanding store credit there, I went to Sears.
Back home I cut a link using a grinder, which turned out to take just a bit longer than expected (that metal is tough!), and with a piece of wire from a hanger and some rope, I was in business.
OK, maybe not quite so fast, took a couple tries to learn how to pull for a smooth, effective cut, but then it did work!
- Exposure to ideas breed ideas
- Having easy access to, and being handy in using tools (like the grinder) and assorted odds and ends (rope, wire) let one "reduce to practice" an invention painlessly
- By publishing this I lost the international rights, and would have to file for US patent within one year max. Probably neither matters, since I see little of patentable interest here
