Sawzall is a great tool for more serious fabrication. Hand portable band saw is useful, but for some jobs the sawzall is the one to use.
Cardboard Aided Design is the low budget CAD.
8. My father.
Why my father?
He was a master fabricator...of B.S. stories to get people to buy cars from him. No story about 'fabrication' would be complete without my father (deceased, thankfully) being included.
He was also an ornamental fabricator in that he would also come up with interesting stories concerning how much money he would blow on Christmas gifts for the family (I'm recalling a gift of a Not Transformer/Not Gobot at age 12 that he swore up and down was $200).
