Topic tags/keywords: combination square question

I have an old Miller Falls combination square that has gotten slightly out of square. Is there a way to tune these up and return it to being truly square?

I have a Stanley that was not “square”. There was not any way to “adjust” it and I’m sure the Miller Falls is no exception. I did square the Stanley, because I also have a machine shop and was able to machine the head to square. I have a Starrett, but I keep it in wraps, using it to check the squareness of other tools and for machining projects. The Stanley is used for everyday woodworking projects.

You could just replace the head, but you could buy a new square for a little more than for the head alone.

I’ve read people saying that one of the two spots in the head that the blade rests on can be filed carefully with a fine file to bring them into square. I’ve been meaning to try it but haven’t yet.

I’ve filed one of my PEC double squares to get it back to square. You need a needle file and some patience, but it isn’t hard by any stretch.
