By no means my first, but definitely my largest home-engineering project, was the construction of a woodshop in an unfinished room of our house. I asked my parents for permission and described the precise dimensions of the counter-top and re-purposed cabinets to be installed, but to their later dismay, I did not inform them of all of the dust that would be produced. (2014 - present, always a work in-progress ☺)
        Among my first projects which integrated electronics with woodworking were  the assembly of Bluetooth speakers. By first cannibalization, and eventually directed electronic component searches, I built different forms of battery-powered, wireless, and wired speakers. These projects were functional physics that everyone could enjoy and were repeated many times with different attributes based on recipient and use. (2008 - present)
        When I was younger (back in the simple hand-tool days), I lacked the money to buy choice lumber, so I turned to the ubiquitous pallet. Depicted is a beautiful end-table constructed of a few cedar and poplar boards originating from pallets dismantled in my driveway. I was extremely lucky with one pallet and retained three sets of coupled boards, allowing for the book-matching seen in the left picture. (2013)
       It seems that I am always in need of shelving. I keep lots of things that others wouldn't if I perceive those things may still have a use. This means that I am a hoarder of sorts -- a very organized hoarder. I built the rectangular, recycled-pallet bookshelf first (2015). When that one filled up, I designed and constructed the screw-less and glue-less square bookshelf (2017). The latter had long been an idea of mine, inspired by the joinery techniques of the Japanese.
        Wooden bowls are fun and artistic lathe practice. (2015 - present)
        Sharp knives are safer, but sharpening knives requires a fair amount of skill --- unless you have an automatic angle knife sharpener. I devised this little sharpening contraption for chisels, knives, and planes. Now, I can make blades sharper, faster. (2018)
        Using a foam-board lamination technique I use to this day for fixed-wing aircraft, I produced this inlay case for my recurve bow. One of my most persistent wood creations, this case still serves its original purpose, eight years and many drops later. At that time in my life, the most efficacious method of creation involved scrap-wood, a hacksaw, a drill, a box-cutter, and some foam-board. (2011)
