I had a wheel disintegrate. So, I replaced all four. I saw more rust when I had it flipped over and got overzealous and ended up taking all the tubes off and cleaned everything up. The problem has been in putting it back together. The way tubes seem straightforward. The sit against a stop in the tilt base and then they sit tight in the tie bar. Is that correct?

Yes, correct. Later if you have issues sliding the headstock or carriage this can be because slight variation in the tubes resulting in them not being parallel. Starting with the seams of the tubes either both up or both down often minimizes this. The seam is usually visible on the inside of the tube.

The bench tubes seem to be an issue for me. They are seated on the tilt side, right?

Yes. If I remember right though the 'stop' might have evolved. Looking at mine it is a pretty definitive stop.

My issue is that I think that I have a tilt now. The way and bench tubes are level, but the tilt-base side of the unit won't roll on the wheels. Also when in drill press set up, the headstock is way out of plumb. Leaning away from the other base.

Yours isn't the first, we've had some lively discussion on this here on the forum. In the vertical mode, the way tubes should be very close to 90 degrees relative to the bench tubes. It sounds to me like there is a problem with how the Base casting is mounted to the bench tubes.

Any advise on adjusting the bench tubes to correct this?

My suggestion is to disassemble the machine far enough to remove the bench tubes from the Base casting. Make sure you understand the mechanical features in the casting, including the stops. Check to make sure that the bench tubes have not been crushed by the clamp bar, this can create a slight bend at the end of the tube. There isn't any real adjustment or alignment for this, if everything is right just make sure it stays that way as you tighten the bar clamp. If you don't see the problem by this point, I suggest providing pictures of the issue.

Apologies if I missed a thread addressing this. Thanks!

I just hope this is not a forewarning for me.
