A Steinway flange has its centre of gravity about 12 mm from the centre and weighs about 3.05 grams, whereas a Schwander flange with washer has the COG 20 mm from the centre and weighs 5.20 grams. That makes a huge difference in the initial turning force already acting at the centre before you add your weight at the screw hole, which will be 23-24 mm from the centre in both cases. And then you can make things even vague by saying the flange should just move when you put the screw in it. Which screw? The oversize Steinway screw weighing 3.8 grams or the Bechstein screw that weighs only 2.85 grams. Greetings, When you mention the flange's center of gravity as for example the Steinway one (above), is that 12mm measurement taken from side to center of flange, or from it's side to the center of the flange screw hole, or from the front to the center of flange or from flange;s rear to center? Please expound/clarify. Thanksd Julia Gottshjall Reading, PA **************A Good Credit Score is 700 or Above. See yours in just 2 easy steps!
