Things started going wrong once I strayed from my original concept of an all-in-one machine and tossed-out the monitor arm. I was pretty happy with the case so far because it went together easily and as an added benefit, I had not needed to solder anything. From that point on, I made the decision to avoid the propane torch all together. Soldering that much pipe inside an apartment really isn't appropriate (nor safe) anyway. The pop-rivets make an adequate substitute for soldering, and the result is a bond almost as strong. A pop-rivet is inserted through a hole that has been drilled where the tubing mates with the fitting. Easy, or what?.
