The repetition lever has a small effect in driving the hammer
shank.<br>
To prove it, increase the distance of the jack below the rep lever;<br>
you will get lost motion until the jack comes in contact with the
knuckle/roller.<br>
<br>
On a soft blow there will be slight motion of the hammer but on a firm
blow<br>
the jack does the lifting, spring tension taken into account.<br>
<br>
The repetition upstop screw prevents the small effect of the lever to
lift the<br>
hammer past letoff, especially on soft blows; hard blows become
checked-in.<br>
<br>
After the lever has engaged the upstop screw, there is a lift offered by
the lever<br>
as the key goes through after touch. Again this is only noticeable on
soft blows,<br>
not firm blows which check-in.<br>
