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?

It is a crapshoot but not necessarily always on a bad side. I have Antique Sound Labs amps made in China. Build quality and sound quality are very good.

There is play between the bearing and the platter if I press if my fingers very slightly onto the edge.

The bearing itself is mounted straight and secure - I've mounted it myself. Platter is made out of glass acrylic. The distance between the platter hole wall and the outer edge of the bearing is not even. At the bottom it is tight and there is no play, but at the top if I push with my finger slightly on a platter you can see through the platter the top portion of the hole becomes "more" in contact with bearing so there is side to side play.

This does not sound idiotic at all. I do not know much about this table so I am not even sure which side is top and which is bottom and I tried it both ways. I will wait to get home tonight and try Bob's suggestion of various positions to see of there is one that reduces or eliminates wobble.

Hey. The wobble video is wobbly. The table was on a floor and I did not have good support. Thanks for the advice. I will try that out. The platter is not sandwiched.
