Ever so slight platter wobble

I have a bix DIY table that I got from a friend. I noticed that when I look at the bottom of the platter or actually put a solid object underneath the edge of a spinning platter, every revolution the platter will touch the object. You can hear it. The wobble is tiny less than 1/2 mm at the edge. I dont have an arm for this table yet so I do not know how it sounds and I am wondering if I should even keep it. Will 1/2 mm impact sonic performance. Scientifically speaking it should not, right? Since whenever the platter dips, so will the tonearm. Do non diy or high end turntables also have tiny amounts of wobble?

This may sound idiotic, but are you sure you don't have the platter installed upside-down?

A slightly tapered bearing spindle matched to a slightly tapered hole in the platter (both narrower at the top) would provide an inherently stable fit, assuming good machining of course.
