A question from Steve Black about pedal changers

[Steven Black]

After installing pedal changer into guitar, how easy or hard should the fingers and the sizzor plates move back and forth before springs are installed.

[Lane Gray]

Without strings or springs, they should be effortless, almost floppy, but only perpendicular to the axle.

[Steven Black]

Hello Lane, thanks for the reply, I am working on one that binds some, I should be able to fix it today, just did not know how loose the had to be.

[Bent Romnes]

Steven, I ream out the axle hole to .003" oversize. The rivet through the raise and lower fingers is pressed in place by a jig in the vise and just tightened enough so there is no wiggle room but still rotating freely

[Steven Black]

Thanks Bent, I have another question about spring return tension since the changer is no longer binding, how much tension do each spring gets, is there a rule for how tight they should be?
