Like working on my car, working in high energy physics in graduate school involved periods of dis-assembly, periods of upgrading/fixing/preparing things, and then periods of putting things back together in preparation for the next experimental run or test or whatever. During that process, there was this wonderful transition day where you realized that everything that you were putting together wouldn't be taken apart again until after the next real experiment. That was the day that the wrenches first stayed on "tighten".
Well, I've gotten there with the beetle on this round of changes. The engine tin is in, and the new heater boxes are installed:
I'm now finished with what I want to do to the bottom of the car. The next time I go out to the garage, I will take the car down off the jack stands and work on getting the battery compartment ready to re-install the battery.
