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.

Best, Scott

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.
That is more than .005 out in regard to flatness. You wouldn't be able to see .005 very easily at all. FWIW, .002 bearing clearance is huge. The ones I've made have been <.0005 clearance. Never had a problem with oil covering the surface area either. Just saying...
