DOUBLE SPRINGS - CLIPS these simple springs placed in fixed points (along the GP hammer shanks) helps to recover the specific key weights losted from frequent hammer heads shaving. So they give back the feeling of "heaviness" without changing/placing new key leads.
Certainly it does not replace a perfect sealing done by a professional following the traditional methode.
Anyway, it is helpfull to those who want to save on costs and speed up time by working on old hammer heads without replacing them.
It is necessary to use a GRAMM WEIGHTS for keys (item code 1264) to find the exact place for the clips (1.38 g). Combining these two opposite weights, it is possible to obtain the right weight (it is obviously necessary to take away the two "wings" that open and close the springs, because they could be an obstacle for hammers movements).
This is a simply methode to get a fast and cheap result and if you want to take them off, the process is very simple. You also preserve the original key leads. In any case, we suggest to get in touch with a qualified technician, who will advise you the best solution for your piano.
