Mine will not unscrew and after purchasing two different types of spring compressors, neither which worked on the springs, I gave up. I found some beautiflul springs that are similar to the AFCO, but less costly and neutral in color. Mine are aluminum and I used the black magic springs that you recomended. The AFCOs are blue and yellow and don't go with any color scheme. I think when they are seen at Bensen Days, they will become very popular with Dominators.
