As you can see, the key has to pretty much make it back up on its own. = There is a repetition spring to bring back the jack however, and if th= e hammer is checked high enough and the return spring is strong enough = it is possible to get the jack under the knuckle quite quickly, aiding = in the return of the key. That said, the key has to be friction free e= nough and weighted appropriatly. It simply has to get moving on its own= . Not much you can do except regulate checking as high as you can get awa= y with, get rid of excess friction, and make sure you have enough weigh= t back of the balance rail pin. Cheers RicB Ed writes: I dunno what is involved in these actions. It would be easy enough to = place a weight on the end of the key and see what happens. regards, Ed Foote RPT ------=_NextPart_38742.4475616667.627 An HTML attachment was scrubbed...
