I've owned a Fessenden, Sho-Buds, and Fenders, but never an Emmons.
What do the allen screws adjust on the changer end?

Those are for tuning the lowest pitch of a string you split tune.

If you have maybe string 6 that has both the b pedal raise and the g lever two semitone drop..if you push them together you can tune the two changes acting together which mathwise is the one step up minus two steps down equals one step down...eg a semitone.
that gives you a minor chord with the 8 6 5 grip.
amazing invention...easy to use...builders need to use fine threads though...course threads are finnicky |

Split tuning will work on any string you raise and lower. A good example is string six. Tune it open to G sharp. Press the floor pedal and tune the hex end A. Now press the floor pedal again and the knee that lowers that string together. Tune the lower hex end to G natural. Now press the knee lowering string six and tune it to F sharp using the Allen screw also called the split tuning screws. I hope this helps. The idea is to get a tuneable note between a raise and lower.

Okay. So any string that has a raise and a lower, the split screw sets the open note of the string.
Correct? |

No.
On the 6th string, for example,
the Keyhead tunes the G#
The nylon nut on the raise rod tunes the A of the B pedal.
The nylon nut on the lower rod tunes the G note of the combination of B pedal and the whole tone lower,
the screw up top tunes the F#
This is because the tighter a string, the more travel it needs to change pitch the same amount. So to drop from A to G is bigger than G# to F#.

Anyone got a illustration to clear it up?
Didn't realize how complicated it is in my tiny brain. |

The "split tone" is a note between a raise and a lower change. The screws allow you to precisely tune that note. difference.
example: 5th sting, If
a pedal: raises B-->C#, and
a knee lever: lowers B-->Bb
The pedal + lever together = combine to give you an in-between note or the "split tone" between the C# and Bb. You use the screw to tune that combination to a useful note......in this case = "C" |

Tony, that screw tunes the A#, not the C. You tune the C with the rod on the lever

WOW!
That's interesting!
So much to learn, so few braincells...
So far I'm only using my lkl knee lever and have it adjusted to go to F# like pedal C or 3.
I use it with a & b pedal for a minor chord... |

Right you are, I just got caught up in the moment......I gotta remember - Think, then write, then proof-read !  |

Tom, I agree that a regular #10-32 screw is fine for everything else but too coarse for this purpose. But what to use instead?
A 5mm fine has about 50 tpi but I won't fit European rubbish to an American invention.

Does the key tell us what size screw (57) is?

On the Zum, I believe it is 8/fine or 10/fine (I don't recall which). It doesn't bear any real force, since it transfers wasted motion to the raise finger)

Paul, that's for the three-rod method. The cap screw is a bit different.
