Hi, my name is Jordon Saffron. I have been rolling along on various contraptions since I was little. From skateboards, to skates, to bikes, that is how I've gotten around since the age of 10. I've also been doing my own repairs for almost that long. Did you know that skateboard wheels each have two ball bearings? I found that out when one of my wheels broke. I started wondering how ball bearings work and how they're made. That led to lots of research on ball bearings--and that led to lots of research on industrial topics in general. And all of that led to this site! I hope it helps you learn something, because it has sure taught me a lot.
