I posted a photo of this lyre in an earlier post, but without the soundboards. There are two soundboards, though you can only see one in the photo - one either side of the frame obviously.
They're held in place by the tension of the strings, which pass over a bridge, which bears on the sound board.
The soundboards are turned from cypress pine, which I glue-laminated in 20mm wide strips, then turned on a lathe. Rather pretty I think.
The roughish looking frame at the bottom of the lyre is just a stand I put together to make it stand up for the photo. I'll tidy it up one day, as it works well.
The lyre actually sounds pretty good, but I've no way of getting a tune out of it, as I can't play anything.
all the best
