i have to much travel in my F lever . the pull rods are in the top hole , would it reduce the travel if i put them in one of the lower hole's?

A lower hole would lengthen the travel, Calvin
Actually, the E to F lever is the one with the shortest stroke on my homebuilt. It has about a one-inch travel at the end of the knee lever and the pulls are actually in the lowest hole of the changer finger.
I take it you have it on LKL?

| Also, depending on the make of guitar, you should have several holes in the bell crank. Make sure that the pull rod is in the lowest hole (when the guitar is standing) |

yes it is on the LKL it came from the factory set up this way. it has 4 other holes that i could put it in . but you just said that would make the travel longer not shorter

Putting it in a hole farthest from the shaft (as Bent said, the lower hole when the guitar is standing) will make your pitch raise higher up for a given amount of lever travel, like a higher gear in a car transmission. This will allow you to decrease your lever travel, by adjusting the lever's stop screw and making your lever move less distance for the original amount of string raise.
If it's already in the hole farthest from the shaft, check to see if you have excessive slack in the rod, which equates to an excessive gap between the tuning nut and the raise bar. |

The way to look at it is. The hole the farthest away from the cross shaft will shorten your travel, but will also make a harder pull. Be sure you don't have a lot play (unused play) in your travel.
Hope this helps.

Okay, the hole closest to the cross shaft makes the travel of the pull rod (and therefore the amount of raise) shortest, and the lever travel itself is set by the stop screw. You want to put it in a hole farther away from the cross shaft (thereby making the pull rod move farther), and then adjust the stop screw (located on ether the cross shaft or the lever itself) so that the lever doesn't move as far (cross shaft rotates less degrees).
This will make it so your pull rods move the changer as far as it originally did, which is what you want for it to be in tune, but the knee lever itself will not have had to be moved as far to do it. This will make it stiffer though. |

Additional: changing the bellcrank hole position and doing nothing else has no effect on how far the knee lever moves. The distance the knee lever moves is set by it's own stop screw.
The trick is to adjust that stop screw so the lever doesn't move as far, and increasing the mechanical advantage at the bell crank (by moving it to a hole farther from the cross shaft) so that it still moves the pull rod as far as it needs to.
