This really owes more to the wood (spalted beech) than to the woodturning but may be of interest - design as requested by a nephew & his fiancée!
Diameter 370mm, base laminated softwood ply (screw detachable so the top could be used as a board). (Top) coating hard wax oil - needed to be vegan and food safe but could be refinished with any suitable oil.
A fabrication detail - the beech top is of uneven hardness and it is tricky to get a very good finish even with very sharp tools. So more sanding than usual, which leaves it slightly uneven, though not enough to be an issue. And yes - for those who abhor chucking points the (of course necessary anyway) base recessed circle is also dovetailed for a chuck...
