Hi, I just discovered these silent beauties. I am on the hunt for a Necchi BU. I saw several on youtube and wondering how some machines run so quiet and others not as much. Do people "treadle" their vintage machines because it makes them more quiet?
I must admit, the reason why I fell in love with the BU because of it "silent running". If this is the reason I would definitely do it also. Is there any websites, or classes that show how to do this?
