After you have 6 pieces of smooth dough, you will begin to roll the dough until it is super thin (1 mm).
To do this, you will run each piece through the pasta machine on consecutively smaller and smaller settings until the dough is thin. I have gone to smallest setting when I use super strong flour (14%), or setting "6" when using bread flour (13% protein). You may also try using every other setting to save time, so rather than go from 1 to 6, use settings 1, 3, 6, and 8.
As you finish each piece, you can consider using a rolling pin to 'stage' the dough as it comes off of the pasta machine. If it's too sticky, you can very very lightly dust with flour.
After you finish the first piece, lay it flat on a long work surface. If using butter, whip it with the shortening, and then paint/grease the top of the dough sheet by smearing a thin layer of shortening all over it.
After greasing, you will begin to roll it up into a cigar/cylinder shape by tightly rolling it starting from the short end. Gently stretch the width (aim for about 9 to 10 inches in width) and pull tightly as you roll to ensure there are no gaps.
After you finish with the first piece, repeat this process with each of the remaining pieces of dough and add to the roll to make one large roll.
You will end up with a cylinder that is about 8 to 9 inches long, excluding the pointy ends. The ends will be trimmed off after it has chilled.
