I am building a small lap harp. The pillar and neck are hawthorn the sound box black poplar. I am not a joiner I am cutting mortice and tenons, 3 of, forming a triangle, no glue, held together by the string tension of about 300lb, there will be a twisting force as the strings on the neck are offset by a half inch from the centreline. What are the correct proportions of a tenon? I think I read there is no hard and fast rule but the cheeks and tenon should feel 'balanced', sort of 1/2 for the tenon, 1/4 for each cheek?
