    hi
    can someone tell me the best way to replace hammer butt springs in a  
    kimball? it looks like some type of cloth that holds the spring in  
    place. how do i get it out? what do i use to replace the cloth? (i  
    have the springs from Schaff already)
    
    ?

    Cut through the cord with a scalpel blade each side of the spring 
    coils; remove the broken spring, push out the cord from the sides 
    towards the middle using the flattened end of a wire or centre pin; 
    buy some butt spring cord.
    
    If the cord comes without a pointed end ready made, remove the yarns 
    from the centre for about 2", soak the remaining braid 'tube' with 
    glue and twist it tight to give you a thin hard end to feed through 
    the holes and the spring.
    
    Adjust the coils of the spring before installing so that the spring 
    ends up at a right angle to the shank as in the picture.
