Seemed simple enough. I had payed rapt attention to the dismantling, so it wasn't too hard to copy it. Not satisfied with my speed, however, I cleaned it, reassembled it, then set about the process again. By the time the hour was up, I had done the whole thing through at least half a dozen times, and was approaching something resembling decent speed - in my opinion, anyway. When the Corporal came back, I was just finishing putting it back together for the eighth time.
