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. Threaded pins should not be spun in with a drill.
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.
- 3" long
- .250" diameter at threads
- 5/16" through hole
- Square tip .176" across flats
- Black oxide finish
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. 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.
Try a D bit (.246") for maple, ash, or bubinga, and a 6.2mm bit (.2441") for walnut, sapele, cherry, or plywood.
