In a large mixing bowl, use a whisk to combine together the flours and the salt, breaking up any lumps if needed. Then use a large spoon to create a well in the center of the ingredients.
Add the eggs, one at a time, to the well you created and then add the olive oil and water to the well (see #2 above).
Working the center of the well where the wet ingredients are, use a fork to to beat the mixture while incorporating the dry ingredients as you work your way out from the center (mixing gently to avoid breaking the well).
When the dough begins to come together into a cohesive ball (it will be a shaggy dough that is both well-mixed and lumpy with no dry spots of flour) you can transfer it to a well-floured work space.
Use a bench scraper or your hands fold the mixture together until a smooth dough ball forms.
Next, knead the dough by hand for about 10 to 15 minutes until it becomes smooth and elastic.
Once your dough is smooth and elastic, shape it into a ball and then tightly wrap it in plastic wrap. Allow the dough to rest at room temperature for at least 30 min or up to 3 hours.
After your dough has rested, lightly dust a clean and flat work surface with flour. Then divide the pasta dough into eight pieces that are evenly sized (cut in half and then cut each piece in half until your have eight pieces). Loosely cover each piece of dough with plastic wrap so that they do not dry out while you are working with the other pieces of dough.
To make the fettuccini noodles, one piece at a time, roll the piece to a quarter inch thick rectangle. Then cut the dough into noodles, you can use a pasta machine or use a pizza cutter to slice the dough to about ⅛" wide.
For cooking the pasta, boil a large pot of salted water and then drop the pasta into it. Stir the pasta occasionally and cook until the pasta is tender, which usually takes (about three to five minutes) depending on the shape and size of the pasta.
