craftsman drill press run out

i took the belt off and turned the spindle by hand
placed a block up against it and did my best to measure it as it "wobbled" out

best i can tell there is 0.65 MM with the chuck on (sorry, i only had metric feeler gauges, that is 26 thou)
and 0.30 MM on just the spindle (12 thou)


just for fun, i tossed a drill bit in there, and about 4 inches below the chuck the run out is 1.8 MM (70 thou)
im sure you can see how 70 thou at the tip of a drill bit can be an issue


so, it seem to me that there may be a little kink maybe in the spindle up high and the further i move down (or away from it) the more exaggerated it gets?
