Hi Steve,
you know the sad thing .... those sheeters exist for about $20 here,
but the sad thing is, they will only make a 4" pizza

What could possibly do that you are asking eh ?
Well, my mother-in-outlaw has a "sheeter" that we have used to make homemade
pasta... the last time I used it was about 10 years ago, but remember using it, and it make beautiful pasta.... it nicely built too .....
It was totally adjustable also, so you start with a thicker dough, run it through, then turn the dial to make the sheeter rollers closer together and then run the dough thru again....
and then again, and again, until you have it at the thickness, or "thin-ness" that you desire.... the thing worked very well.
Darn, - why don't companies make one that is about 18" in diameter.... boy that would be so amazing !

here's something like the one I used :
