Excellent tutorial! I would have a lot of time when I started if I had gone through this first :-)
Most of my Ibles use some kind of tool or process that can present a safety hazard of some sort - so I recommend people have a "safety" section along with their materials/tools lists if needed. If someone is new to a process, they may not know to wear safety glasses or hand protection or whatever. I also will point out any special hazards (like smoke from soldering) in those particular steps as well.
