I forgot to put in my post that you have to release belt tension first or it will make it seem like the bearings are tighter than they really are if there is a problem. I'll go back and edit it in.
In order to get the tolerances tight enough the casting and Quill would have to be hardened and ground so they wouldn't wear each other away and cause more slop with use but that would add to the cost of the Drill Press. But they're pretty worthless for precision work as is.
