TW Acustic Raven AC Owners with 3-4 arms

You must remove the bottom corresponding section that holds the footer,  then the top section will unthread from the plinth.

Pcosta,

Thanks a ton for the quick response. But how do I do that if the table is sitting on my rack? Do I need to take off the (2) arms and the platter first?

Earl

No need in my experience. Find a few soft cover books or fold a towel on top of a hard cover book to protect the plinth from scratching and lift the front of the table put the books under the front high enough to unthread the side you want.

Got it, thanks again!

Enjoy

Just for fun I unscrewed all feet and put the TW Raven AD directly on a Townshend platform. The more sits outside the platform and had to be leveled. Due to asymmetric weight I had to move the TT around on the platform for leveling it perfectly. 
Satisfied with the SQ but I have to move back once for checking… my 60 years old back is not ok with that for a while.

In theory I should have placed tt and motor both on the platform I think ?

Yes.
