My new profession

So our research group decided a while back that we need to put our experiment in a cleanroom. For those who don't know what a cleanroom is, it's a special room that keeps the level of dust or other contaminants inside very low. In most cleanrooms, air is continually circulated through the room, passing through very fine filters on its way in. Different applications require different levels of cleanrooms. Computer chip manufacturing is done in very clean environments, where workers have to wear bunny-suits (these often appear in Intel commercials).
Anyway . . . we needed a cleanroom. We couldn't just buy a stock one either, because of some of our special requirements. I shopped around for some quotes, and we decided that we'd build one ourselves. Since then, I've been a cleanroom contractor. For the past couple of months I've ordered 700 pounds of steel, 2 $600 fans, and various cleanroom parts. I've learned to weld and I, along with my advisor and a post-doc in our group welded together the 12-foot tall frame. After painting it, we maneuvered it into our lab and set it up. It's a good think we have a gantry crane in the lab, because it's a bit difficult to maneuver 300-pound, 12-foot long objects around.
One problem, however, was that we had to set the frame up before it was really ready to be set up. Because the experiments in our lab are so sensitive to vibrations and movement, the owner of one of the experiments wanted us to do the heavy lifting while their apparatus was down for repairs. So after it was set up, I still needed to drill lots of holes in the top of the frame. For those who've never drilled through steel, it's a bit harder than wood or drywall, and balancing on a ladder wouldn't let you get enough leverage to drill a hole in a reasonable amount of time. To be able to get these holes drilled, I've hooked up my climbing gear and either climbed onto the cleanroom or clamped a cross-beam onto it to stand on.
I should finish the cleanroom in the next couple of days. Besides being really fun, I now have a new marketable skill--welding. I'm now safe in the knowledge that if someone comes up with a theory that explains all physics, and thus puts physicists out of their jobs, I can go get a job at the shipyard as a steelworker.
Here's a picture of me working on the cleanroom. The cleanroom frame is light blue, our experiment is in the big shiny bell jar, and the wooden frame is a temporary setup to hold some calibration equipment. I'll post a picture one it's all finished.
