how do you true front wheel hubs?

how would you set up and center the front wheel hubs in a lath to true the face?

I have access to a lath, 3 wheel hub,s and books on how to use a lath but I would like to know from some one who has done it before.

as a note I am not resurfacing rotors. I am only working on the hubs right now

Any auto parts store can turn the rotors on the proper disc brake lathe...Its really a simple job....Our parts store cut hundreds over the years

And no comebacks ither......

Well you got answers for the rotors. Do you really mean remove the lugs and true the hubs?

You talking about this?-

Drilling out the rivets- remove bearings-then having the hub machined?

I went through w/ it because the hubs looked really crappy after I pulled the stock rotors off. My machinist really just cleaned them up.

I then mounted my new rotor/ hub/ bearing and checked for run out and used shims as needed.

You have access to a lathe....make some tapered holders that locate on the bearing races....the one for the inner bearing will have a spud on it to mount assembly in the jaws of the chuck....use a threaded stud from a mill hold down fixture set to put tension on the outer tapered holder then.....true the face of the hub to the bearing races. Doing this you will pretty much find you will never again have to shim a brake rotor for runout

New rotors typically have run-out right out of the box. I sold & turned rotors for a living and it didn't matter where the rotors were sourced... they had significant run out. Truing the hub is great start but you probably will find that any rotors you purchase will still have to be trued to get within spec.
