The measuring cup for Ronco Pasta Maker has been lost. Where can the part be purchased? (the www.popeilfamilystore.com/pastamaker webstore has been closed and no response from Ronco.com). Alternatively, how do the specialized markings on the cup translate to using a traditional measuring cup.

Here are the measurements for basically every pasta maker:
Full Load
Liquid: 2 eggs and water to total 7 oz.
Flour: 3 1/2 cups flour with a small amount of olive oil (1 tsp?)

Half Load
Liquid: 1 egg and water to total 4 oz.
Flour: 1 3/4 cups flour with a small amount of olive oil (1/2 tsp?)

I measured and wrote amounts below in my instruction book in case I misplace the measuring cup.
Full Load
Liquid: 2 eggs and water to total 7 oz.
Flour: 3 1/2 cups flour with a small amount of olive oil (1 tsp?)

Half Load
Liquid: 1 egg and water to total 4 oz.
Flour: 1 3/4 cups flour with a small amount of olive oil (1/2 tsp?)

Always use 2 cups of flour to 2 tbsp olive oil and add water by tablespoons at a time starting with 4 tbls.
