Those blanks appear to be about 4"x4" (?). Do you always use such a large blank (pepper mills). The reason for my question: I'm not a turner, but I'm trying to make a pepper mill right now. My first one ( a prototype exercise) was/is a 2 1/4" square blank, and actually it seems large enough. This is not a crush grind type...I don't know what that means, but I know this isn't one. Anyway, if I were to make a few for gifts I wouldn't have a source for blanks that large. Maybe I'm doing something wrong. I apologize for the dumb question......
