Never worked on *my* Sonex in a hotel room, but have some information on tools.
We attended the Sonex workshop in Feb 2008. As you probably know, you bring your own tools. I put them all in a small bag inside my suitcase. No prob; got there, the tools were still in my bag, so all was well.
Well, on the return trip, we were diverted because of WX to LaCrosse. Since LaCrosse only has 3 gates and about 15 TSA agents, they had plenty of time to check things out (we checked our baggage). While we were waiting for the flight, one of the agents came trotting up the stairs with a picture of the x-ray of our bag, and he disappeared into the TSA offices. As we were boarding the flight, the same guy was at the checkpoint, so I asked him if there was an issue with my bag.
He said, no, the tools (giant Andy snips, vixen files, etc.) were not the issue, but the corded electric drill got them kind of excited! Guess with the wires, coils, gears, etc., it was hard to tell if it was packed with C4 or not.
