Are those cheap pasta rollers built with gears to drive both rollers? My tortilla press/grain mill has slick 3" aluminm rolls, with gears, and works great. I may try it without the gears, they are so poorly cast the noise is b-a-d. Smaller rollers need knurling, larger rollers need neither gears nor knurls. I'll try the cast iron pasta roller with the slick geared bronze rolls with a sample this weekend when next I brew. $7 at Salvation Army- do you think they would have sold it to me if they knew I was gonna make alcohol with it?
