A bit of a near disaster today. I finished off cleaning up the back, and then cut out the shape based on my template. However, I should have turned the template over before drawing the outline. My dulcimer is not symmetrical (it has rotational, but not mirror symmetry), so I ended up with the best surface on the inside. Blast! Anyway, I had to sand and scrape the other side and it turned out fine.
I have now made and started to fit the cross braces - I am using four in a simple ladder arrangement.
