<BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><FONT face=Arial>One cause of key bounce, besides low up weights, is overworked <BR>>wippen support springs...

The more the spring works above 17 <BR>>grams the worse the effect. This 17gram cut off is echoed by Lloyd <BR>>Meyer, Renner USA and I agree with it, although I find that pianos <BR>>feel more normal to more pianists when key weighting is designed so <BR>>that spring tension only reduces touch weight 9-12grams.

When using assist springs we usually set <BR>them to assist 10 grams on note A1, graduating down to no assistance <BR>by around note C52. We've set up no. 6, which we're bringing to <BR>Rochester, with assist springs set up as mentioned above.<BR><BR>Best regards,<BR>Ron O.</FONT></BLOCKQUOTE></DIV>
