I found that in my attempts with non-wood against the bushing, that I was deforming the end of it where the pressure was exerted. Base-pin then did get too tight. Experimenting, I was able to open the end a bit with a punch, and then sanded it smooth.... I tried and now the base pin fit is a little tight.Gil.
Would one of you who knows more about base-pins and bushings give your ideas here?
