A boring head project.

I would take the tires off of the wheels. I would also head off to the local junkyard to get a chevy axle. Hopefully the axle will fit in the spindle of your lathe. Baring that you could make a cradle for the axle to sit in while you turn the wheel to check the concentricity of the wheel.

I am assuming that your friend got these wheels for cheap. If he paid 5K for them he should have just bought the proper wheels for his Toyota.

At least remove the tires.

I was able to get the coax arm over more, I thought it was maxed out. Which do I trust more the Noga flex in the spindle, and a tenths DTI, or the coax?

I can stay away from the anomaly, I'm within a couple of tenths staying away from that small sector with the DTI, the coax keeps jumping, and it's hard to see if it is settling on one graduation.

If you are running the spindle with the co/ax don't. Your situation because of the knick in the bore is the problem. Free the spindle and turn it by hand at every 90 degrees to avoid the knick in the bore. Turn the spindle in the same direction every time, either CW or CCW not back and forth.
 
Looks good! I never knew I was supposed to use all of the toe clamps at the same time.
 
My shorter studs would not reach, good thing I had a few. It was solid though. :)

Nice looking wheels Mike and looks like a great finish . Who set that up ? Jed Clamp ett ? ;)
 
I would think using a tenths indicator is overkill.
There’s gonna be manufacture tolerance and if those are a no name rims that can get worse. The center bore can be buggered from when they mounted the tires or mounting the wheels. What kind of clearance did you give for the spindle hub? Once the tires are put on I would think your tenths are gone.
 
Ya know, ain’t’ it funny how a job that you figure is a piece of cake can turn into a real basket full of eels?
Been there, done that, I feel your pain.
 
My phobia with this job was determining exact center because the wheel stud openings are deeply recessed. If the center register moved the tight fit shoulder lug nuts would not thread on to the stud. I got the Blake indicator to center exactly, I chased the zero which did take some time. I alternated between the Blake, and the tenths indicator, and they were never an exact match, probably my setting up maybe, or the Noga flex on the DTI vs the collet mount for the Blake? I chose one horse to go with, and stuck to it. My measured hub was 4.1885, and I bumped the Criterion a half thou at a time till the adapter I had slip in without pushing on it, and the actual hub just fit with no noticeable play, but would rotate in the bore easily.
I did not take a farther away shot, but the tire was a 35" x 12.50 on a 20" rim, that I struggled to lift by myself weight wise to get on my 50" table.

When I have a wierd problem like that I make a plug to fit the hole and then indicate on that.
