I looked at the site for replacing the spindle bearings, but it does not sound like what I see in my CHNC.
I stripped off the masking tape today. Don't go cheap like I did and use regular masking tape, spring for the blue stuff. The tape was a pain to get off cleanly. After removing the tape, I installed the carriage. I might even be able to mount the lathe to the stand this weekend.
In the cross slide there are various studs and holes. I figured out what they all are but two. In the picture below, the one with the question mark looks like a broken stud. The other one is a stud that had an Allen head underneath and is accessed from the bottom gear bolt hole. Does anyone know what they are for?
When I was removing the center carriage ballnut housing, one of the alignment studs broke. These studs are threaded 10/32 so they can be removed by threading in a long 10/32 screw and pulling them out from above. Anyway, I broke one off. It broke slightly below the sruface. I tried drilling it out but it was hardened. I ended up tig welding a 10/32 screw to it and pulling it out. There was absolutely no damage to the housing from the operation as you can see in the picture below.
