</font>Thanks for pointing this out. It is something I had not previously considered and what you say about how the variation in knuckle height affects regulation makes sense.<br>

<div>I want to bring this up again because it is something not
considered</div>
<div>beyond an overall knuckle size.</div>
<div><br>
</div>
<div>A set of shanks will have knuckles at various heights, meaning
the distance</div>
<div>from the shank to the end of the cover. Sometimes as much as 1mm
with</div>
<div>varying distances sprinkled throughout.</div>
<div><br>
</div>
<div>A shank with a 'taller' knuckle (or maybe it wasn't pressed in as
far) will</div>
<div>have the wippen resting at the lower elevation than its neighbor
with a</div>
<div>'shorter' knuckle for the hammers to be at the same height. This
lower</div>
<div>wippen will have to travel through a slightly greater distance to
reach the</div>
<div>Let Off button and consequently attenuating the after
touch.</div>
<div><br>
</div>
<div>My contention is that even knuckle heights will produce a more
even</div>
<div>after touch. It will also produce a more even Let Off button line
due to</div>
<div>the more even geometry or shank ratio. I have proven it on
many</div>
<div>installations.</div>
