Getting into self-employment just as Obamacare is starting to roll out might be something to consider as well.
The wife carries the healthcare as her plan is better. So that part is not a concern.
The restoration stuff, with the metal surgery, fabrication, welding, body/paint work etc. I don't know that it's a "hobby" for me, I think of my hobbies as hunting, fishing, shooting and the tinkering part of owning hot rods and classics. I enjoy tinkering and tuning. The all out surgical restoration process... It's not nice work, it's ugly, dirty...
