That corresponds fairly well with the coil takeoff angle from the pin. Getting that angle is another problem. When I was driving pins with my 4lb hammer, I could drill the block at a specific angle and the pin would be at that angle after I drove it in. Since I started using a palm nailer, things changed. For reasons I haven't been able to define, pins driven with the palm nailer, especially if there's some tension on the string, will migrate and rotate toward the bridge. I've had a couple of pianos end up with the pins nearly on the rear edge of the plate webbing holes, and with little or no back lean. Using a transfer punch larger than the pin, and smaller than the plate hole, I can mark the pin locations forward of center, and add a couple of degrees to the drilling angle to get the things to center at the pitch angle I want after driving them. Who else has run into this with palm nailers? Ron N
