The problem with turning the axle stubs is that the axle isn't straight (by design). It's got a slight bow to it so that when loaded up, it flattens out.

I can see trying to chuck that into a lathe and having it wobble all over the place. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />

Jake's probably right though - better to have standard components that can be purchased / replaced wherever you happen to get stranded.

What started out as a "I think the old trailer could use a new paint job" has turned out to be a major production.
