> Hello List
> The only whippen support springs I know of have a different name. The are

> attached to the Lever(whippen)and Flange. I have them in my Hamburg S&S 
> Model "A" and use them to even out the playing weight to conform with the 
> factory settings given in the Steinway Service Manual.

>> Actually, not.  If you want to reweigh an action that has these springs,

>> your target, and then re-attaching the springs and using them to bring 
>> your final
>> downweight to target. You can get lighter keys, this way.
>>   Another approach is to find your optimum frontweight curve which leaves
>> the downweight approx 6-8 grams heavier than your final target, and use 
>> the
>> springs to both bring down the weight and even out the downweight at the 
>> keys.
>> This is easier than individually adjusting strikeweights.
