CBH Winding a string loop IV — Broadwood loop

• Always read the accompanying technical description! More harpsichord stuff @ https://www.hpschd.nu Carey Beebe demonstrating the winding of a Broadwood-style string hitchpin loop. The secret of a successful loop is all in the angles and the tension. To begin, the tuning hammer is hooked over the loose end of the wire. Both parts of the wire must be wrapped around each other in order to produce a double helix which will hold pitch. If the loose short end of the wire is able to twist around while being held with the same tension and somewhat less than 90° to the clamped long length, a double helix will automatically result. To avoid forcing a permanent twist which would make the string sound false on the instrument, only a few turns are made before backing off. The loop is continued by eye for perhaps 35 or 40mm. To make the distinctive Broadwood-style termination, the wire is loosely twisted back over the double helix for a few turns, then a brief revolution made at exactly 90°. Finally, the loose end is twisted around in a circle to kink and break it off far more cleanly than cutters allow.
