Tired of banging your wheel set with a hammer trying to install your axles?  Did you know you run the change of bending an edge while hitting your axle?

This tool is the perfect mate with my wheel gap gauge!On the flip side is the hub packer for packing fine graphite in the new molds.  What is a Hub Packer? I have a video on YouTube.
