For some time, Piano Forte has been offering special leads for weighing off piano keys.
Several features make these the go-to material for technicians doing precision Touch Weight and Inertia Adjustment and regulation, to get that “Touch to Die For”.
- The material is a very pure lead – considerably softer and hence easier to swage than other lead slugs.
- Our leads are not tapered like slugs from domestic sources. Tapered leads will only contact the edges of the hole at their thick end (unless someone can bore a conical hole to match their shape). Our leads will never rattle around in their hole and are less likely to loosen and dislodge
- Our leads are extruded, not cast, which means they have no voids and are are very uniform in size. They are a consistent very snug (thumb pressure) suction fit into holes bored by Forstner bits
- The best thing: our leads are extremely consistent in weight. The variance is 0.1g at most from one piece to another. Conventional leads have variances exceeding one gram! See the following email I received from one technician:
