Exactly right Hornet

After taking all apart, I see that the armature is making contact with the surrounding magnets. I will try your dowel method to align them. It appears to me that replacing the bushing may be impossible (for me anyway). The armature isn't real
loose in the bushing but I may try plating the ends with nickel to take up some of
the slop. We'll see. I do have 2 further questions,,,,one of the screws holding the magnets in is loose because the hole in the housing is stripped. Not sure how to fix that ...I may try putting JB Weld in the hole and drilling it undersize.
Also, the wires that connect to the carbon brush housing were soldered on. Other motors I've seen have a spring looking ring that slid over these brush housing parts.
There are screws on there but I took them out and that doesn't seem to do anything.
I'll either have to solder the wires back in (which will be difficult to access) or
see if I can fabricate the spring type connectors. Please see my pics. I'm not ready to give up on it.

Hi OhioVacuumes, I looked at your bushing for the armature and looks almost out of round , try to nickel plate and see if that helps first, if problem remains , look for another bushing that fits your armature nice and then drill out seat in housing to accept new bushing you may need to do some custom work to do this or maybe replace with a sealed bearing small enough to fit, it is one of those things that you may need to play around with to make work or you could try to drill it out to accept a bronze sleeve?
With the stripped threads I would put a small copper wire in the female thread and bend the wire over edge so not to fall in ,then screw in your screw, I have tried JB weld for this before with negative results, JB weld gets brittle when applied in such a thin coat and turns to dust when screwing back in, also there is a chance your screw may get locked in, you could also try a( medium ) Automotive locktite on the screw so if you ever need to take apart again it will come out. You could also use a little bit bigger screw and tap out the female end to fit. Hope some of these ideas help you out with your restoration.
Could you post some pics of your brushes so I get a better idea on what you mean with the soldering.

Thanks again for the info. !
I haven't done anything yet with the motor...been way too busy at work.
I will try the soft copper wire method along with some locktite that is not
permanent on the hold down screw.
See my photo #1.....The 2 screws seem to hold down brass tubes that the brushes
slide in to. I took the screws out but the "tubes" will not move. The wires are soldered on to these "tubes"...you can see some solder on the right side.
I'll try nickel plating rather than attempting to replace the bushings....It doesn't have to run perfectly, I just want it to run fairly well.

I see now what you are talking about with the brush holder, try removing the screws and put some penetrating oil in the holes and give some heat to the metal and with a dowel of same size tap them out, see if that will remove them, if not prewire before installing motor to give you some extra space to connect the wires together, make sure to solder them and shrink tube them. Use wires that can handle heat.
Hope this helps you.
