The factory violin I’m restoring came to me with an old ebony tailpiece in the tulip style. Since i’m replacing the spruce fingerboard (yes spruce), with one of rosewood, I decided to make a matching tailpiece. For those interested in making a similar tailpiece I documented the dimensions. Here are some pictures of a preliminary tailpiece, along with to-scale pdf of the dimensions.
