What is a good blue collar job for one who has little experience but is willing to learn?

I'm a college grad with a not so great employment history, and after watching shows like Bike Off and American Chopper on the Discovery Channel during weekday mornings while I remain out of work, I am now starting to toy with the idea of doing good ol' manual labor to help pay the bills. I'm not talking about being a floor sweeper, but a job requiring a little more skill and higher pay. One position I am considering is one where you lay tiles. I have a tiny bit of experience doing that.. any other ideas? I would probably start out doing odd jobs and stuff like that. I don't have a vocational degree or certification and definitely am too entrenched in debt to consider going back to school. And no I'm not open to taking out a loan.
