Dusty Strings threaded tuning pins combine the style and usability of taper pins with the proven reliability of piano tuning mechanics. Unlike tapered tuning pins, threaded pins won't work loose or require resetting. Harp players appreciate the smooth turning and greater control of threaded pins, and harp builders appreciate the easy installation.

Threaded pins press smoothly and quickly into place with an arbor press, making it easy to achieve uniform alignment. They can also be twisted in by hand, though it's important to understand that our tuning wrenches are not intended to handle that sort of heavy use on an ongoing basis. Threaded pins should not be spun in with a drill because the heat created by the friction can burn out and enlarge the hole to the point where it will not hold the pin firmly.

It's important to advise harp owners to back out the tuning pin by several turns when changing a string, just as they would with a zither pin.

Drill bits:

Threaded tuning pins are .250" in diameter at the threads, so you'll need various undersize drill bits, depending on your wood species. Before drilling your harp's neck, do a sizing test in a scrap piece of wood of the same species. The test will determine the best fit with the wood species you are using. The harder the wood, the larger the hole needed. The fit should be firm, but not too tight to turn the pin comfortably, or you could risk twisting the head off the pin.

As a starting point, try a D bit (.246") for maple, ash, or bubinga, and a 6.2mm bit (.2441") for walnut, sapele, cherry, or plywood.
