Modified for = accujust hitch pins. From a friend I borrowed the Balwin instructions. Briefly::: Without bass strings installed, string treble and set = bearing to (zero) with strings at pitch. No load on board. =20 Now set specified number of notes starting at bottom to 1 div (.5 = degrees). Number of notes depending on model of piano. Then next group = of notes to 2 div (1 degree). Then the last group to 3 div (1 1/2 = degrees). Lastly install the bass strings and set at pitch to 1 div (.5 = degrees). Is that really what it says? The bubble gages I used at the factory were = supposed to be calibrated to indicate a deflection of 17 minutes of arc = which was supposed to translate to 0.5% string downforce. I.e., with a = string having, say, 175 lbs of tension a bubble gage deflection of one = gradation indicated a string downforce of 8.75 lbs. I have to admit I = took the above at face value and didn't do any checking to verify, but = that, at least, was the theory.
