I'm going to coin a new term... "problem shock". In his 1970 book, Alvin Toffler defined "future shock" as a personal perception of "too much change in too short a period of time". The accelerated rate of technological and social change leaves people disconnected and suffering from stress and disorientation. Here is the connection to rocketry. When you build a kit, the directions are laid out in a logical order, basically engineered for ease of assembly. In scratch-building, however, particularly an oddroc, as you run into problems, they get deferred. Eventually, when all the fun, easy to do stuff is finished, all you have left are the problems and they pile up in front of you like a giant wall. With a deadline, it could become "too many problems in too short a period of time".
That being said, here is what I have done thus far today. I (obviously) need to vent the altimeters to ambient air pressure. I could vent the internal bay to the inside if the bottle, and vent that to the outside air, but I feel there will be a time lag in doing so. Having a supply of "extra" air is why bagpipers can inhale while playing a long note. Back on page 2, Eric and Rex suggested venting the air with flexible tubing. Unfortunately, I put that in the "I'll get to that later" pile. It would have been much easier to attach the plumbing prior to assembling the av bay. I ended up drilling a pair of 5/8" holes in the bottom end cap, and was lucky that the threads of the quick-connect fittings screwed perfectly into the holes with no further complications.
T minus 4 days.
