Continuing with JD's Garage Plasma CNC build I'm building the gantry blocks. These use 608 bearings, set screws, and 8mm (5/16ths inch) rod. The rods are cut to 3 1/4 inches long and are press fit into the bearing block while leaving room to insert bearing washers that were 3D printed and the 608 bearings. This particular one I used a rod that I did not clean up after cutting it with my angle grinder. On the other rods I ran the ends of the rods on my Delta 1" belt sander with an 80 grit belt. This caused the rod to get stuck within the 3D printed bearing block with no way to remove it. The position of the rod relative to the bearing block doesn't give any way to grip the rod with pliers.
This video demonstrates how I used a tap to remove the rod. Not shown on the video was me using a drill to drill the end of the rod out on my drill press. This allowed the tap to act like a rod extractor and I was able to provide enough force to pull the rod out entirely.
