 Driving me nuts. My second string lower (full step) pretty much bottoms out because the k we lever hits one of the legs. How to I maximize the throw so it doesn’t need to go quite so far? Also note that if i tighten the changer tuner it starts to change the string pitch as there is no play (which I always have). This is a session triple raise double lower. I have the rod connected to the lowest slot on the bell crank. |

Is this on RKR? I recall having a similar issue.
You should be able to position the lever so it doesn't hit the leg.
Some other tests that you can do to see if it will work, take an allen wrench or screwdriver, pluck string-2 and push the String-2 Lowering-Finger in to see if it will lower all the way to C#, to see if it will even do it. You may need to go to a thicker gauge string.
You may be able to loosen the Return-Spring tension a bit to allow it to lower easier.
Also look at the knee lever Linkage to make sure it is working as good as possible, no loose connections or slack.
Also make sure the Bell-Crank is tight on the Cross-Rod.
It sounds like your endplate-tuner is already at the no-slack point, so don't tighten it any further.
FWIW I tried to add the D#-to-C# lower to the RKR lever that lowers my E's-to-Eb, and it made the throw really long and did not work well for the more important E-to-Eb change, so I did not end up having that change on that lever. |

Thank you. It is RKR. I'm able to get it BARELY. It's a fine line I guess. Thank you for your help  |

| it may be as far as it will go, but look at the travel adjustment on the knee lever itself. you need to turn the adjuster until you have a longer pull (be sure to back off on the adjustment on the pulls) this will move the action of the lever over....thanks jack |

If everything else if working fine, you could experiment with going to a thicker gauge string, which will give a little more tension, and then when you hit the lever it will lower to a slightly lower pitch within the same travel range.
There is also an Alen-Screw in the side-rail (underneath) that stops the cross-rod from moving any farther. You may need to screw that in, to allow the cross-rod to move farther, which will allow more travel distance for the lower.
You can see in this pic, that I actually put the top end of my RKR knee lever in a Vice, and bent it so it wouldn't hit the leg. It is Aluminum and bends pretty easily, but be careful, you don't want to ruin the knee lever
This helped for me, but depending on you body/leg shape, may or may not be of help to you.
