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> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
