Maybe Pianotek has started having them ground down. I purchased mine a couple of years ago, and there are no signs of any attempt to resize it. Maybe I will break down and take take it to a machine shop. I got it, it didn't work in my drill press, and so I set it on the shelf. Roy Peters I just received one of those from Pianotek. The shank diameter is .500", but it looks like someone held it out the door of a speeding car and ground it on the curb. He sure had a good eye for .500" though. Tom Cole
