Standard 3/16 inch zither pins are used to hold and tune the strings on the kantele. The holes for them must be drilled 1 ¼ inch deep and as close to vertical as possible. A drill press was used to ensure that the holes were the right depth and perfectly vertical in the instrument. I thank Charlie Engle for the use of his drill press and assistance in completing this step. The drill stand base was not large enough to support the kantele properly. Charlie helped by holding and supporting the instrument in the awkward positions that were needed to drill some of the holes as I operated the drill press.
