The roding chart is used to define the undercarriage rods arrangement and more precisely the hole you choose on Bellcranck and changer to get the best résult and desired setup. There's no real universal convention to write a roding chart so every player must write is own copedent. Anyway, here we will try to establish a way to write his copedent.
The guitar is turned and the number is from the guitar board to you. Now the person who read our roding chart knows in wich way we have to work on our steelguitar.
Write like this:
P1: 10 33 533
We can read for P1 (pedal 1), string 10 like this:
Pedal 1 / Sttring 10 / Position 3 on bellcrank (from the guitar to us) / Position 3 on changer (from the guitar to us). it's very simple !!
For the rest our roding chart will be note like this:
P2 613 343
P3 522 443
LkL (for me E to F) 812 422
LKR (for me D# to D and D to C#) 955 255 (with half stop: 955 245)
LkV (for me B to A#) 545
RkL (for me E to Eb) 845 455
RkR (F# to G# and G# to G) 715 143
For the bellcranck: the hole close to the steel body will give you easier action but need more course and the hole far from the steel body will give you stiffer action but shorter course.
For the changer: The hole close to you will give you easier action but need more course and the hole close to the changer will give you stiffer action but shorter course.
