Square grand regulating specs, please!!!

You should be able to tell by taking a good look at your typical what 
works perspective with the action.  That said.... dip was quite 
typically 6-8 mm on older squares. I dont know if 1870 Stieff qualifies 
as being that old... but I would be suprised if it was much deeper then 
8 mm.

Hammers you make yourself. Not a big problem. Jurgen should have useable 
felt.  Doeskin was often used in layers... all or some of them.

I've always set the dampers to engage at half blow regardless of the 
actions specs with older instruments.  I find this works out the best.  
Earlier and the darn things are usually miles above the strings at full 
blow, and later yeilds a weird touch.

    I'm doing an 1870's Stieff. Does anyone know what the
    key height, key dip, let-off and checking should be
    set at? Also: when in the keystroke should the dampers
    engage  And where can I get a set of those itty-bitty
    hammers ???

       Thanks!
