What could be happening here?
I just installed a 5th string lower (G to F) and, although it works, it sometimes catches somewhere and the string doesn't lower at all (despite the nylon tuner moving appropriately).
I looked under the guitar again and got Mrs R to push P5; see how the spring is coming out crooked?

| There are times that, due to excess tension on the return spring, while lowering the note the raise scissor will pull away basically chasing your tail. This is generally solved by moving the lowering rod to the hole in the lowering tab that is furthest from the changer axle and adjusting the lowering return pressure. The G-F change on the C6 requires a bit of a throw. |

Jim:
Thanks. I have no doubt that your information was spot-on accurate but you're not taking account of my ineptitude.
I'm almost ashamed to tell you - and the world - what I did wrong!
I said the lower was 'intermittent'; sometimes the string lowered, sometimes it didn't move.
Examining my 'handiwork' with the guitar on the table, I couldn't believe what I'd done. The rod hadn't gone through any hole in the changer - it had gone between the 4th and 5th fingers! Sometimes the nylon would catch the changer and pull it, sometimes it passed between them.
So yes, Jim - I was certainly chasing my tail. I've now located it correctly (in the only available 'lower' hole) and it reaches the F easily.
The pulls on E9 (lowering 9,6,3 a half-step each) need addressing. They're too spongey and require the pedal to be really pushed hard. Could I fix that by relocating the rods nearer the far end of the 14-hole B/Cs (say, #12)? Would they activate faster if I did that? They're currently quite near the cross-shaft. |
