Platter swim is undesireable in that it will cause the arm to go up and down, putting undue stress on the cantilever and stylus, as well as affecting the pitch of sounds. I am not familiar with your turntable, but some of this may be a setup error. Put your platter on an absolutely flat surface, and see if the platter is true, or not. If it is, look at how the female part of the bearing is affixed to the plinth and see if there is any looseness. Finally gently rock the spindle to see if there is any play in the main bearing.
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?
