    I believe the Universal Method also has diagrams, albeit of an older harp. Bochsa, that is.

    Here’s something that may interest you. In many older harps of all makes-almost anything built before World War II)- the rods that connect the pedals to the action cross over each other inside the column. There are different versions of the cross over, but the most common one is this:

    Take a blank piece of paper and write the following letters in this same order across the top of the paper.

    E D C B A G F

    Now, at the bottom of the paper, write the following:

    D C E B F G A

    Now take a pencil and connect the letters at the bottom to the letters at the top. In other words, draw a line from the bottom D to the top D, C to C, etc. That’s what the rods do inside the column!

    Carl, why did the manufacturers do that? Was there a technical advantage?

    Cathy- It has to do with where each of the chains ends at the top of the harp. In order to avoid crossovers in the chain around the second or third octave, they decided to cross the rods inside the column. I just finished rebuilding a Wurlitzer DDX(which will be up on my company web site soon if you want to see it) and the crossovers are even worse in that one. Most harps of that period had discs only up to O F. But this model had discs on OOG. So in order to do that and not have any crossovers in the chains, they reordered the rods. In that case the order looks like this: Again, write down the following letters at the top and bottom of a piece of paper and then draw a line from the letter at the bottom to the corresponding letter at the top.

    D C E B F G A
