My E-F knee lever has drag, and sticks if I go between lowering and raising the E's. This video shows that moving the F lever actually moves the adjacent "plates", which lower the E's.

That's not normal, is it? I've squirted some Tri-Flow between the plates, but it didn't seem to help. Am I on the right track?
Thanks,
Al

OK, I think I answered part of my question: one finger causing the other to move seems normal. But the raise fingers/lever don't return all the way without an extra nudge.
Is there a common point of friction?

check to see if your nylon tuners are to tight. also,
the barrel guides on the rod going thru the changer sometimes gets worn out on one end. back the tuning rods out a little at the bell cranks. then re tune and see if that will work.

Or turn those long spacers around.
One Fo'Bro (Donny Hinson?) believes that Triflow, with its dry nature, actually is inferior to light oil, since it can't migrate once dry.
If you have a sewing machine oiler, with the proboscis, put a DROP of light oil on the pivot rivet. While part of the scissor might normally change angle when the other part is pulled, it is NOT normal for the raise finger to pull away from the stop bar when the lower finger is pulled or vice versa. If that happens, you have either friction, or binding.

As Lane said, the angularity of the lower finger changes when you activate a raise, but unless it's actually pulling the lower lever away fronm the stop, it's a moot point. In other words, it's supposed to operate that way. I see nothing wrong with the raises, so the problem is probably in the lowers. If the lowers aren't returning true, they are probably overtuned. As long as all the fingers are firmly against the stop when no pedal or lever is activated, all is normal. Be aware that a few cents of deviation is also normal, and may be due to hysteresis elsewhere in the guitar, but this does not really affect playability, as a rule. You cannot expect everything to operate exactly if you're using a digital tuner for these observations. "Close enough" is good enough.  |

Al.. On my old M.S.A,I had a tuning barrel develope a groove in it, and this groove would hang up on the barrel hole creating the problem you have.
My solution was a visit to my local auto parts store,
(taking one of my barrels), got some brake line tubing that matched and made my own .
Hope this helps... |

Thanks for all the responses, guys.
After more investigation, it seems like the shaft itself, which the knee lever mounts to, is(was) not moving freely. I hit it with some Triflow(before I read your recommendations against it), and it seems better. I may get brave and take the shaft out and clean and re-lube.
When I bought this guitar last Spring, it was quite well-lubed; as in almost dripping with oil. I haven't done any maintenance, so perhaps I need to give a once-over.

Nope. Replace the nylon bushings if some idiot oiled them. The oil will make them swell just a bit and bind. What you want to do is replace them with dry nylon bushings, and never oil them.
Michael Yahl has 'em.
You made new ones, Eddie? I had some with grooves in them, and I just turned them around

| Make sure the stop for the knee lever (the thing that sets how many degrees of travel for the lever) that fits on the cross shaft is not up adjacent to the bushing/body of the guitar. This just happened on my MSA classic and all I had to do was loosen the stop and move it out from the body of the guitar a fraction of an inch so it was no longer in friction with it. |
