In a large bowl mix 1 3/4 cups of flour and salt together. In another bowl mix the eggs, water, and corn oil. Make a well in the center of the flour and combine the wet ingredients into the dry ingredients. Sprinkle the remaining flour onto a kneading surface, turn out the dough and need for 8 to 10 minutes. You could also use a dough hook on a mixer and kneed for 8 to 10 minutes. When I've don this I haven't really need to add any of the extra flour. The dough should be smooth and elastic. Cover and let rest for 10 to 15 minutes. Divide dough into quarters. Roll out in machine until you get to setting # 5 (1/16" thick). Let rest for 20 minutes. Cut as desired. You can use the machine or roll the pieces up and cut. I let the noodle dry over night or for a few nights.
