The Black Hole strikes again- I had been fabricating a hinge from brass channel- bent, cut, hinge holes drilled- and while beginning- literally- to do some final shaping, it flew out of the pliers and into- THE BLACK HOLE! It's my model room- it's a relatively confined space- but it has lots of stuff- open boxes of stuff- and I can't find it. I did hear it hit something- no idea what- and now I have to decide whether to start over (possible, but somewhat less enthusiastically engaged upon), or to continue looking (pulling more things apart)- or hope I suddenly see it looking at me with that "what- me?" look on its face.
