Kim,
In order to get a gasifier built, someone is going to need to weld. But that someone doesn't have to be you. You could find a good blacksmith or a technical college or high school metal shop
class to take it on. Welding is such a valuable skill to have and the price of welders has come down so much. For $1000 you can get these new small 200 amp mig welders from lincoln or miller. A weekend welding class could bear fruit.
I do lot's of crazy stuff, usually without much money just from being resourceful and making trades. If you could barter your time for welding time that would be cool.
