Some questions for you long-time uke builders: How thin can you take a hardwood top on a soprano uke, e.g. koa or mango? And do you alter/add bracing to adjust for that? And does that depend on the stiffness of the top? At this time, I am working on my third soprano, a curly mango top, and am in the range of 0.059-0.058" thickness on the top. My previous soprano had a koa top, c. 0.065" thickness and the center single brace, and it's nice, but I still want to push the limits a bit. Comments? (I'd prefer polite ones, thank you)
