Does it make sense to cut the wire on the barrel adjuster of that one right off as the stop on the C pedal has to be hand tuned (atleast that’s what I’m doing) then it can’t catch on anything and might be easier to tune ?
No don't ever cut a spring tip off flush on barrel; then yes; you will have to hand tune and that makes it much harder to hand tune with another barrel on that rod; that's a big NO.
I just like a spring tip that is just enough length to catch the puller/roller.

I took out the 10th string rod and filed that part a little and replaced the rod with one that may be straighter, it looks like that helped for sure. Now for some reason my 5th string A pedal raise seems to go slightly flat (not a ton but a little) but it is making a sound at the changer and I think after the naptha bath I might need to oil the pivot joints on the scissor better. I will also look at filing that one a bit if I notice any friction at the changer. Also I notice the bellcranks for the E-F#raise and B raise (C pedal) are tight up against eachother and it’s possible they are rubbing up against eachother when either the A or C pedal is engaged. I might try and move them just slightly apart so they aren’t touching. Progress is being made 😅

Yes if the rollers that the rod goes through are touching at C pedal 4th and 5th strings? that is BAD....those rollers need to have ZERO FRICTION as the rod runs through them, because as they get pulled; they change degrees and will cause that small binding of the rod.....boooooom that sounds like the whole 5th string rod prob. Continue on brother.

Should the barrel adjusters be pretty close up to the bell crank to reduce movement? I know they can’t be touching (overtuned) or else you can’t tune it but should I reduce the travel as much as possible to help with tuning stability? I read something you posted on another thread about how that can cause it to go out of tune , although that was a rack and barrel system I am assuming it’s similar?
