In large bowl, mix flour and salt; make well in center. In small bowl, beat oil, eggs and chilies; pour into well. Stir with fork, gradually bringing flour mixture to center, until dough forms and rounds into a ball. If dough is too dry, mix in up to 2 tablespoons water. Roll and cut as directed below. (Use additional flour when rolling and cutting noodles.) Place fettuccine strips on towel; let stand 30 minutes.
Hand Rolling Method: On lightly floured surface, knead dough about 5 minutes or until smooth and elastic. Divide into 4 equal parts. Roll dough, 1 part at a time, into 14x10-inch paper-thin rectangle (keep remaining dough covered). Loosely fold rectangle lengthwise into thirds; cut crosswise into 1/4-inch strips. Unfold and separate strips.
Manual Pasta Machine Method: On lightly floured surface, knead dough about 4 minutes or until smooth and elastic. Divide dough into 4 equal parts. Feed dough, 1 part at a time through smooth rollers set at widest setting (keep remaining dough covered). Sprinkle with flour if dough becomes sticky. Fold lengthwise into thirds. Repeat feeding dough through rollers and folding into thirds 8 to 10 times or until dough is firm and smooth. Feed dough through progressively narrow settings until dough is paper thin. (Dough will lengthen as it becomes thinner; it may be cut crosswise at any time for easier handling.) Feed through fettuccine cutting rollers.
