The keys are so long that the action frame is also. When you pull out the action to check somethings like whether or not the jacks are jamming into the rep. lever window felt, the keyframe flexes so much that you don't know if you're getting the same dip with the action half in your lap as when it's in the piano. Yes, you can rest it so that the glide studs are on the front edge of the keybed, or you can push the balance rail up with your knees, but there's still no positive indication. --David Nereson, RPT
