    I've built a bunch of this style for circle track race cars. We made an aluminum plug to limit heat distortion during welding. a few we had to ream.
    I would ream it out. try msc.com to find the correct size reamer

    As Proto said you can ream it. If it is only a thou or two you might try flap wheeling it. To make an easy and cheap flapper take a piece of round rod, split it in the center with a dremel or hacksaw and slip some abrasive strips in it. Longer strips for larger diameter, shorter for small diameters. Spin it full speed in a drill and it will take a tad bit off pretty uniformly.

    Oh, I'll try an aluminum plug on the next ones. I guess it would be better to have to press that out than having to ream afterwards.

    Whoa, I looked for a reamer and they are expensive, I'll try the flap wheel on this one.

    Thanks

    Did you get the axle apart?

    There’s a clip in there. You need to hit it with some force and some mass to get it apart. That or put it in a press.
    Hold the axle in a vice and hit the star towards the end of the axle. Thick walled tubing over the axle with a lip you can pound on will usually take the star off.
    HIT IT.

    I did not, I think I need to use more force. A tube around the axle is a good idea.

    Flap wheel worked good. About 5 minutes with a hand drill did it.

    Here I'm getting my camber adjust sleeve nuts ready for tapping.

    Glad to hear that it worked for you.

    I turned an aluminum plug and stuck that in the next cup before I welded. Worked great, the aluminum plug came out easy after cooling and the bearing slid right in. Thanks for the tip ProtoDie!
