Well I can make them but can't make any music with them, that's my wife's department. Here's a few pic of some of the finished Harps, these are all Celtic Harps.
The 2 small Harps have 22 strings, or 3 octaves, and I made those a couple Winters ago for some locals. The big one is a 31 string Harp I made for my wife a few years ago.
Then there is this 24 string Harp (3 1/2 octaves) with an ERC sound box, I made 2 of these
I also made a 28 string Harp last Winter, haven't taken any pics of that one yet. It's a bit of a unique Harp in that I used Willow for the sound box, apparently the Irish liked Willow for Harps. I used Diamond Willow, a local tree that grows in swampy areas, and I had to search a long time to find something usable. I made that one for my wife and she named it Willa, for special reasons.
Unlike commercial Harps that make extensive use of plywood all my Harps are made of solid wood with solid Spruce soundboards, it makes a difference in the sound. The only one that doesn't have a Spruce soundboard is the 31 string Harp and it uses Spanish Cedar
My wife ordered plans for the Hurdy Gurdy a few years ago, I just didn't get around to making it yet.
I did take extensive pics of the Harps as I was making them if anyone is interested
