I have a support for a dial gauge (APSCO ?), did not find the gauge to be easy to use, mostly because the gauge tip is rounded, it may be necessary to ground it (make it flat) the readings are not very even from note to note, and I don't have the official method to translate the readings in pressure (if possible) Nowadays for bass strings , some adjustable foot may be necessary. Is not it more accurate to build little 3 feet gauges that apply well on the bridge and the string's rest ? (3 screws on a wooden stick are doing the job fine enough I've find) Isaac OLEG Entretien et reparation de pianos.
