Scheidmayer&Sohne Grand

[Alan Forsyth]

Schiedmayer had their own type of action between 1860 and 1900. If indeed 
your piano falls into this era, I hope this helps.

Apparently you have to adjust the blow distance or the depth of touch or 
both to prevent the hammers from either dithering or blocking. The hoppers 
must be adjusted in line with the hammer notches . You must take up lost 
motion until there is a paper thin clearance between the hoppers and the 
hammer notches when the keys are in the rest position. The repetition 
springs must be adjusted as strong as possible without them lifting the 
hammers off the rest rail.
