This plate: <https://www.ebay.com/itm/Bison-Adapter-Back-Plate-for-6-Diam-Self-Centering-Lathe-Chucks-MG/182914465135?hash=item2a968d3d6f:g:vc0AAOSwvR5aEzfc> Looks like, in the 5th image, to be bigger than 6". Like maybe even over 7". And its plain, drill it myself, so I could easily make it fit this 6.25" elderly Bison. For $61.33 in a box on the chair seat just outside the front door, I am tempted.
