Hammered dulcimer bracing

[Russell stallings]

I’m building a hammered dulcimer, the only books I’ve found are for floating sound boards ( which I am proceeding with) however I wish to build one with a fixed sound board. I believe the internal bracing would be different, where can I find pictures or plans for bracing for a fixed sound board dulcimer?
