Hey!, I Happened to stumble upon this forums by doing some google search about removing nitrogen from the air. I did not there was such a forum online until now! I've only been through a high school physics class and touched on Trig in Community College. I decided to take the welding classes and I am currently working as a fabricator. Classrooms are not my thing so I learn alot from books and the internet. But the threads on this site are very helpful and I will post on what I can. I built a dc brushed motor for physics in high school as an assignment, and clocked it at over 2400 rpm on a 9v power supply, I was very excited about that as it was made out of hot glue and a skateboard bearing. I try and apply physics to everyday life to help understand how everything around me works. I am also very interested in advancing my metallurgy, being a welder and all. So thats me, glad to be on the site finally hah.
