Turned on my Record CL1 lathe and made from a piece of Ash about 220mm Square. The underside of the bowl was turned first with a recess to accept the expansion jaws of my nova chuck for re-mounting to turn the inside face later. the underside was turned to a finish before the bowl was remounted tho turn and finish the inside. Finished with cellulose sander sealer and 3 coats Melamine lacquer
