A very simple design that just works. The working looks a bit unrefined but will remove fixed cups. Depending on which side of the tool you tighten it moves both right and left thread designs. The nuts are race car lug nuts with a bit of lug stud welded into one end with an extension that is welded into a 1/2 inch drive hard socket. I need to bit more cleaning of the welds and then paint but I have a new tool In haven't seen in a long time. Smiles, MH
