Been wanting to make one of these since someone played me some recordings of one a few years back. Haven’t got it to work yet, waiting for a good windy day. The structure is maple that I salvaged from an old dresser that someone was throwing out in my neighborhood. I like the grain on the front piece especially. The banding, dovetail keys and bridge are from Black Walnut that I got when my next door neighbor was trimming their tree. The top is spruce of some kind I think? Had it lying around the shop so thought I should put it to use. Finish is linseed oil/shellac/wax in that order. Maybe when I get it to work I’ll post a recording too!
