That's a possibility, or it could be a high spot preventing the platter from seating properly.

Hopefully just a little bit of polish or shave then to let it sit fully flat. Looks killer!
Mine does pretty much the same when removing or installing the aluminum platter, it's so well mated that there is suction.
The platters arrived at the fabricators yesterday. I received this message from the fabricator this morning:

As someone who is married to a Japanese native, I can testify that "almost" is not even in their vocabulary when it comes to results.

I don’t think these guys just drill a hole as we would using a drill press of some sort. It’s a precision fit over the spindle of which requires a great deal of effort to accomplish. I would say if it’s too large he would have to bore it larger and install a bushing. That would be welded in and basically a huge screw up on his part and many hours correcting this.

I just checked on two Japanese DD and the spindles are tapered giving us a tight fit. I bet the GT is also? If it’s tapered how do you mill that?

Hence the precision ground taper cutter that the fabricator is ordering. I'm guessing it's not cheap.
I'm not going to speculate on what tools the fabricator used to make the copper platter for sunnyday and my SS platter. My hope is that the fabricator acquire whatever tools are needed to consistently produce these platters with the precision necessary for a perfect fit.
I'll provide an update when I receive the SS platter back.

I turn on a wood lathe and cut a hole in the center of a work piece by moving the tailstock with a bit in it towards the headstock while the workpiece is spinning, I imagine a machinist would do the same, he would cut the smaller diameter then using a cutter would taper the hole! I’m thinking he just didn’t taper it and has a through hole of the larger diameter! Conjecture, least he’s taken care of it.
Discovered the problem with the YOP-1. Someone made a repair to the switch, and in doing so, oriented the link at the end of the switch 'rod' horizontally, while the slot in the back of the switch is vertical. This changes the length of the rod, because the connector cannot nestle into the switch. So, my solution was to leave the cover un-screwed, and let it sit forward a bit to account for the lengthened rod assembly. Not ideal, but alternatives seem quite complicated as the plastic is all glued together.
I received the stainless steel platter back from the fabricator. It still doesn't fit.
I sent the fabricator this message:
"I received my stock platter and the stainless steel platter and have the stainless steel platter on the turntable. The fit of the SS platter on the spindle is looser than it was before and it still wobbles slightly. The only thing that makes sense to me is that the center hole is too large. I'm not happy with the situation. What are your thoughts on what to do next?"
The fabricators response was that there nothing else he could do, and I could return the platter for a full refund.
I'll be returning the stainless steel platter. I'm doing it as an eBay RETURN rather than a NOT AS DESCRIBED so the seller doesn't take the entire loss on this fiasco. I'll end up being out about $250 for shipping.

I had no idea this was an eBay sale! Couldn’t you keep the platter and find a local machine shop to repair this?

If the hole is too big then you would almost have to drill it out so much so that you could create an insert, otherwise it's an extremely heavy paperweight. I wonder if a little bit of teflon plumbers tape would be enough to fill the void.

It needs a bushing installed to fit snuggly on the tapered spindle. I believe an easy fix for the right man.
Yes, it was an eBay purchase. Oddly it doesn't show under sold or completed auctions, and is not searchable by item number. I can only locate the original listing by clicking on the auction listing in my eBay.
If I kept it it would be at the full price of the auction (~2.2k$).
Undoubtedly an easy fix for the right man. Finding the right man is the hard part.

Bummer that this didn’t work out. It would have been a boon to the GT owner community.

Japanese precision is on another level. Hence the interchangeability of platters between different spindles.

I’m gonna rouse a local machinist to get a ballpark price on a platter, I could be out in left field though and perhaps it’s more work than I’m willing to spend. Is it an exotic type material needed? I’m thinking you guys need a group buy from someone who’s a perfectionist.
