Not sure if anyone is viewing this or not but I like to keep it as a record of what I have done so far.
I cut out my top very roughly today by hand and finish sanding my rosette with my ransom orbital sander. Lesson for future builds: buy a half decent band saw. I also cut out my soundhole. It is approximately 90mm or about 3 1/2".
As you can see, the rosette split when putting it in on the top. So I spun it 180 degrees so the split will be covered up by the fretboard, so no issue there thankfully.
I plan on doing a rough pencil bracing pattern tonight. If anyone has a photograph of a nice parlour x braced let me know.
Oh, one last thing. The stain on the top just above the rosette isn't dirt. It's blood. I slipped with a chisel and dripped blood for about 10 minutes before realising I was cut. It will sand out, or maybe a memento of the build?
