This project is simple to assemble using normal household tools and 20-30 hours' time. Use an electric hand drill for drilling string holes in the soundboard and for installing screws. You'll need two c-clamps and some weights for certain gluing steps.
Decorate your instrument with a Large Rosette!
Sorry it has taken me a little while to respond back to you. Due to a work related injury, I didn't get my hognose psaltery finished as quickly as I wanted to.
I finished my psaltery just before Christmas and I LOVE it. I tuned it slightly different, starting at the B below middle C, so I could play Carol Of The Bells and it sounds fantastic.
I find that I can't keep my hands off of it and am constantly plucking and strumming on it. I have even started to create my own songs.
I cannot thank you enough for offering such a wonderful service and product. Now I just have to figure out which instrument to build next.
God bless all of you for the gift of music,
