    "Uhhhhh... let's start over." You just made the entire argument for the duplex revision! 😆
    (For this unit, 144 / 12 would have been a more practical example.)
    Among the first sales were a group of four to the US Treasury Dept, so that should say something about its utility.
    For the stripped out wood screws, break a toothpick off in the hole and put the screw back in. Works like charm. 😉
    On the nest, I'd guess wasp or something like that. Would certainly have happened during long storage in a garage or something.
    I'm going to guess that the reason you had the error on the first key test was because of flexing of the parts in the unit. I understand that was something of a problem on these early units and part of the reason they changed the system later on.
