MAKE: PROJECTS Eccentric Cubicle Figure 09.82: . . . the by-now-modified reservoir fill cap. The air line fits onto the brass tubing nipple, with the flex fitting over that. Figure 09.83: A stretched-out spring provides hose kink abatement Assembly Having built each subassembly as essentially a freestanding mechanism unto itself, assembling the entire mechanism on the base was essentially just a matter of positioning and screwing the modules into place on the base and running the hoses and power leads. The fluid feed hose I'd originally spec'd ruptured spectacu- larly under pressure with the outlet valve closed. Oops. I replaced it with a piece of gothishly black aquarium air line with reassuringly thick walls. Unfortunately the new tub- ing was heavy enough to be prone to kinking under its own weight, a problem which was easily remedied by sleeving the kink-prone area of the tubing with a stretched-out length of coil spring from the Luxo lamp I'd cannibalized for parts at the beginning of this build. [Figure 09.83] I mounted the intercooler above the hotbox, using another 7" stainless steel saucer and three chunks of threaded rod. This was a solution with multiple benefits: it positioned the intercooler to take advantage of the whole "hot fog goes up" thing, it saved valuable real estate on my by-now rapidly crowding assembly base, and it made the mechanism as a whole look a little bit more like alien architecture from an early episode of Dr. Who. [Figure 09.84] The airflow insertion into the hotbox required an impro- vised PVC T joint and some keepin'-it-real-style duct tape action to seal the hose connections. The expansion joint pictured is part artsy-fartsy nonsense (ooooh, cool . . . shiny! bendy!), part necessity (fluid system in the way, need some- thing that bends). [Figure 09.85, Figure 09.86] The aluminum cable armour coming from the top of the T carries the frying pan AC cord, which snakes around the fog juice tube and connects to the base of the control panel, crimping around a short length of lamp rod threaded into a tapped hole. Because aluminum cable armour is cool. [Figure 09.87] I tested the electrics one circuit at a time, then all at once. Satisfied with the absence of impending shock-based death and destruction, I mixed up a few quarts of fog juice and pre- peared for a proper field test. 294
