spoon.jpgMatt writes in and says “Two bored physicists, a machine shop, a spoon, a leatherman, and a vision…”. Jen bought me a Leatherman tool adaptor for my Leatherman. It came with a few square attachments crytpically referred to as “Robertson,” and I had no idea what these were for. But, what I did need, desperately, was a spoon attachment for my Leatherman. Thinking quickly, I gathered the raw materials and headed to the machine shop with Greg Snyder, my trusty side-kick and budding photojournalist… Here’s what happened.

    Any Canadian tinkerer could tell you what a Robertson is.
    It’s a screw with a square hole in its head that slips on to a Robertson screwdriver and stays there while you dribve it.
    Great for electric screwdrivers and generally fantatically useful.
    The screws are almost unknown in the US — except at some furniture companies.
    Although I do appreciate the occasional utility of a spoon.

    He wasn’t welding so much as brazing or silver soldering the spoon onto the hex bit. Other than that a neat little project. He can also now chuck the spoon in a cordless drill and have a cordless coffee stirrer.

    as the other comment said, the square bits are for Robertson screws. They are actually a lot more common in the US now, although often in combo drive screws that have both the square and philips profile sunk in the head. (but only the square bit works well with them).
