Help with changer fingers please

Post by Marty Broussard »

Folks,
I was removing the changer fingers on my Excel for cleaning and when I removed the axle all of the finger parts fell onto the bench....LOL. The only problem I've encountered is that 3 of them are set-up differently than all the rest. I think they are different because some strings require a different pivot point but I'm not sure. Could someone look at them and provide some feedback?

Note: The guitar was previously set-up with the Newman Uni 12 string tuning.

Lol Jess, I should have removed them one by one just in case but I messed up.

Which one in the picture is the different one? The ones with the movable stud further from the pivot axle in the scissor (the second one in the pic) will have more leverage on the finger side of the stud, i.e. more rotation of the actual finger relative to the amount the pull rod moves the scissor. Seems like those would probably go on the lightest gauged strings since they must travel the furthest to change pitch.

It looks like it affects the leverage on both the raise and lower, but probably more on the lowers. It's hard to tell with out seeing it move. You could probably tell by flipping them back and forth side by side. If the three that are different are like the second one in the pic, I would speculate that they are for 2, 4 and 5, assuming you have the standard lowers on all three of those, but just an educated guess.

If it's the first one in the pic that's different, then it's probably the opposite, those three would probably go on the low strings.

Do you have a pic of the other side of the finger?

Ian, I forgot to state that the one on the bottom with the pivot farthest away from the axle I s part of the group of 3 that are different. When I got home I tinkered with them and I think the difference only affects the lowers but I will hang them on the changer and test them when I get the changer housing back from the machinist.
The opposit side looks like the pic below:
