<div> Working on an upright, I always globally check out lack of lost motion by tugging on the hammer rest rail, however, I came across this piano where there are braces on the back (or towards front) of the rail and I cant check it this way. Now I wonder if this shortcut is a viable one. </div>

<div><br>I guess it's a viable enough test although simple observation should tell you the same thing. </div>
<div>I can't remember tugging on a hammer rail to check for lost motion or lack therof since I can see if there's lost motion or not by how far the backcheck moves prior to the hammer. In fact it's easily checked note by note as you tune since there will be those keys that get more use than others and develop more lost motion than their neighbors.</div>
<div>If I find there is no lost motion I then will run my fingernail at a 45 degree angle across the keys from bass to treble, just forward of the capstans and watch to see if any hammers drop back to the rail indicating the capstans are set too high or that I'm dealing with an asian studio or upright in a school in late spring, summer or early fall. <br clear="all">
