Sutherland Harp Sharping Lever - 3D printed

3D Model

This is a simulated cast brass sharping lever for a celtic or lap harp. Please see the latest version here: [https://sketchfab.com/3d-models/sutherland-harp-sharping-lever-version-2-04c4c5dd75db46f2b535804da4c9e33c]. These are printed in biodegradable eco-friendly PLA (polyactic acid, which is made from corn starch, tapioca & other plant-based materials). Sharping levers are used to engage with the harp strings to sharpen the pitch (by a semitone) by shortening the vibrating length of the string. The prototype levers are 3D printed, & these can then be used to create molds for spin casting in brass, bronze & possibly aluminium or titanium for strength & durability. The 3D printed ABS plastic version of the Sutherland Lever has been extensively tested for many years on a number of Robyn Sutherland’s hire harps - http://www.robynsutherland.com/harp-hire.html, & these levers may be available for sale in the near future… Any enquiries or feedback welcomed.
