<< The bass tuning pins are easily in excess of 300 inch-pounds torque - I will not be surprised when I twist a pin in half. And when they do turn, they jump, and the pitch will change anywhere from 20 to 40 cents. Getting the pitch anywhere near target is a crap-shoot. Any ideas beyond removing pin, reaming, and reinstalling? >> Greetings, If you have one of the smaller palm-nailers, and there is room under the block to use it, you can use it and a short length of steel rod in the tuning pin holes under the pinblock. Drive the pins upwards, then hammer back in to the correct height. Loosen the bass strings, first.
