Hardware Help

I've been lurking into blogs, forum and relative articles just to find solutions with my little, but not that easy problem. I was asked by my uncle to help my cousin out in his assignment. By the way, my cousin is taking up a vocational course in a school within this city. Of course, through the advent of technology, I ended up facing the computer and asking my friend google. Til I found a website that talks about pneumatic tools like, Nailers, fasteners, compressors and the likes. It really helped me a lot for it tackles mainly on the hardware thingy which I've been searching for. I thank much my uncle asking my help about this matter for it also helped me in a way.
