Dear Terry, If you tilt the drill press, and slide the press across the piano on a plank, and keep the drill press base, and arm, perpendicular to the stretcher, the pins will all lean directly toward the stretcher. If, on the other hand, you make sure the arm/head of the drill press is perfectly lined up with the string, the pin hole will be directly angled away (7 degrees or so ) from the string. There's a difference. I am wondering what manufacturers used which. By tilting the drill press in this fashion, though, you are risking having the pins angled this way or that, if you roatate the press base, at all. Indexing lines woulds keep your intended results uniform. By placing the drill press on the floor, or overhead, and tilting the piano, you eliminate this discrepancy. As long as the bit is "plumb" to the floor, all the angles will be the same, regardless of how the base is rotated.
