These are the Digital plans for the Diatonic Bowed Psaltery 2015 version and 1997 version and the Edgar Stamer Chromatic Bowed Psaltery in G plans
Once you have downloaded the plans you will need to unzip the plans using winzip or 7-zip. The use Adobe reader to view and print off the plans set at no-scaling 100% There is a lot of overlap. I suggest collating the plans using a lightbox, or a sturdy window(with care) use pritt stick or magic tape to join the drawings together and to finish of put some extra tape arou.nd the edge for sturdyness.
In the USA you can get zither pins from Elderley music, in the UK from the early music shop, otherwise I may be able to supply some or the odd key from my Lyre shop.
