So which way is it?? ? I use a drill press to make the holes in my grand pin blocks. But the drill press was clamped down, and?I moved the?block on a flat surface of a table.?Unless you can get the drill press over the upright piano, making 100% sure that the angle of the drill press is at exactly the same angle as the previously drilled holes, it would seem to me that using a drill to re drill the pin holes in an upright piano is asking for trouble. I would even be very careful?using a reaming, because a slight variation in the angle in which the reamer goes in would enlarge the hole, or make it out of round.? Just my 2 cents worth, (which?is actually worth 5 cents here in Hawaii.)? Wim -------------- next part -------------- An HTML attachment was scrubbed...
