Categories: all aviation bicycle gadgets misc motorcycle theater Thu, 30 Apr 2009The last few weeks, I keep finding myself not sleeping very well. One of the reasons is that I'll be mulling over a mechanical or design problem as my mind wanders from topic to topic, and I get stuck on it. A week or two ago, I woke up to the realization that I'd designed quite a workable folding welding table, having worked out the offsets in the hinges to get it all to fold up nicely. This morning, I woke up to realize that I'd been running over the process of machining these velocity tubes Michael made and showed me:
I'd worked out, in my sleep, that by his description, their length was predetermined by the angles he'd chosen to cut them at (3° for most of their length, 9° for the last bit, and 6° to smooth the transition from 3 to 9), although that length was longer than what he made. It's a bit odd to wake up and realize how much work I've been doing while, at least in theory, resting. This might explain why I've been feeling a bit sleep-deprived lately.
