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?

What is the platter made of? The fact that the bottom of the platter is uneven may be fine as long as the top runs true (especially if the platter is massive and thick.

The fact that the bearing has play is more serious. Have you looked underneath to see how the bearing is mounted? You might be able to secure it.
