Bed made of mostly turned wood (4)
I believe the answer is:
crib
'bed' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
(Other definitions for crib that I've seen before include "Nativity centrepiece" , "Translation; bed" , "Young child's bed" , "Plagiarise - cot" , "Card game for two" .)
