Lets see if we got this right... You ended up with 11 mm key dip, 46 mm hammer to strings distance, and 2.5 mm let off and there was no aftertouch ? I'd say you have a problem there... :) Quick and dirty is to raise hammer distance enough til you get aftertouch. But you'd probably be best to start from the very beggining, from bedding the keyframe and do a complete regulation in best "make it work" fashion. I dont know the G.Lehmann grand specifics so I will leave that to anyone that may have run into them before.
