Not sure where I got these but I think they were left here by the previous owner when we moved in years ago. They have been in a cabinet out in the garage and were getting rusty. So I cleaned them up hoping they were something someone could use. Some are 1 inch X 8 TPI and the others are 1 ½ inch X 8 TPI. The paint color leads me to believe they were made by Powermatic. One of them has a part number which is definitely Powermatic. But this thread and bore is also used by others. Based on the paint still in the screw holes, I don’t think they have ever been used. And if you notice in the pics, a lot of them have been balanced. Some of these were worse than others so I totally stripped the paint, others just the face. More postings to come.
