Guys , it is not hard to make your own turn table. Ebay , 12 inch lazy Susan , metal shop of scrap dealer buy 3/4/5 ml 15 inch did or if square you can cut it round using grinder . Lay lazy Susan upside down onto plate and drill four holes suiting heavy pop rivets , this leaves the plate sitting some 10 /12 mls in height, I sank mine into floor half this distance which allows easy pull bike onto plate and bike can turn when held level to floor. Foot note , i drill two holes close to. outer edge without interfering with Susan for a longish bolt dome shape, this stops it spinning when stepped on .Also stuck rubber car mat to shape . Total cost 19 quid.
