Got a bit of rust in the hubs, and feel I should clean them out before I run an axle in there. Do I just tape some emery paper to an axle and turn it to smooth out the insides? Thank you.
How about a wire brush turned with a drill?
You could also sandblast them using a fine grit.
A lot of "ELBOW GREASE"
I know about the elbow grease. Steve, I like your idea.
here is a truck load for you Dave!
I've been thinking Dave rather than emery cloth why not use a fine valve lapping compound? It would leave a smoother surface and not remove as much material.
Wire brush and then lapping compound. Sounds like some good ideas. Thank you again.
