Platter wobble - too much?


Hi everyone,

Just working on getting my new turntable dialed in, and the platter seems to wobble far more than my previous table.  I noticed the wobble with the naked eye from across the room.  I've already tried a new sub-platter to see if the first one perhaps had a bent spindle or machining defect.  I only have one other table to compare it to, so I don't know if this type of variation from flat is normal.  Here are a few videos:

Does this seem like a reasonable tolerance, or am I going to do some damage to the cart/bearing/records?  I appreciate any thoughts y'all might have.

I did send the videos.  The manufacturer suggested that the subplatter that they sent was measure carefully.  They suggested that if the right amount of oil is used that the bearing/spindle should fit just right in the hole without any wobble.  I've been experimenting a bit today,  but I don't see any difference regardless of how much oil and/or anything else that I try.   I'll ask for a replacement if I don't stumble upon the answer in the next few hours.  We'll see how it goes.

I appreciate the input from all of you.  Since I only had one other table to compare it to, I didn't know how much wobble to tolerate.

Best, Scott
The amount of wobble to tolerate would be an absolute zero. The motor spindle, platter, subplatter, clamp, spindle, etc. should all be absolutely true. The belt should be uniform and not look like it has thicker/thinner sections as it passes the eye.

Any deviation means that it’s a complete defect. Or Chinese junk.

Manufacturer's comment on the oil is nonsense.
For what it's worth, the email from the manufacturer said:

"I measured the replacement inner platter run out (within the 5 thousands window). The decoupling pad that is between the inner and otter platter can cause more run out by adding its deviations to the measurement. They are now not glued to allow rotation of the position of the decoupling pad to minimize run out.If the bearing has the proper amount of oil their will be no play. the bore is two thousands larger than the spindle, allowing a oil film to separate the parts. The overall run out tolerance of the platter system is + or - 5 thousands."


Not sure what that means in terms of whether the wobble I'm getting is normal.  I just compared the first sub-platter with the second, and there doesn't seem to be too much difference.  Still a visible wobble from my listening position.  Going to send the video of both platters to them and see what they have to say.
What table is it?  It's important to know.  

In the meantime, I would notify the payment processor (Paypal or your credit card company) is there isn't an immediate effort by the seller to refund your money, including shipping.  And let the seller know you are working on getting a refund if they don't do it first.  Sellers don't like black marks on their record since it will cost them money in higher fees.
