Greetings, Having rebushed a lot of these things, I finally found a way that works well for me. I drill out the red felt with a drill bit in the drill press. With the right bit, only the black is left and then it is a simple job to rebush with the factory's modern bushing cloth. It is easy, fast, and looks and performs like the original.
