I am in school to be a mechanical engineer (cal state LA). I also work part time....so i am very tied up, but I had some time right now because of the summer semesters it took me about 6 days, because it was my first time and I had to figure stuff out, I had to also go back and forth to the computer to look up parts that I did not know. I recommend getting a color printout of the article from the tech section, makes it much easier. Also read the whole thing a couple of times....goodluck.
