Having lost my Regal Octofone in a flood, I decided to build a reproduction and have been working on the drawings, molds etc. I have concerns about the bracing pattern on the top. Prior to its demise, the top had begun to sink. It seemed to be lower in front of the bridge and pulled up behind the bridge. I could not detect a loose brace, so I don’t know if it was a result of a bad brace, a poor design, age or too heavy of a string or whatever else. I have seen photos of a couple Octofones posted and they didn’t seem to be suffering from the same syndrome as my own, so I’m not convinced that it is too bad of a design. Anyhow, so I am trying to decide on a bracing pattern. I have posted a photo of the existing pattern. The braces are 5/16” wide and 7/16” at their highest point. The furthest aft brace is much wider but only 1/8” tall. Can anyone make any suggestions?
