POLISHING ARBOR
I made an arbor to polish piston pins and pilot bushings that can be chucked up in my lathe, or even in a drill chuck. First I cut off the head of a long carriage bolt. This one was 3/8” coarse and will fit in a small drill chuck. Then added a nut, followed by a Chevy rocker arm ball (3/8”). Then the part to polish, followed by another rocker ball and tightened up with another nut. The rocker balls work great to locate and center something like the wrist pin that has a larger I.D. then the arbor shaft.
