Vehicle component needing tungsten repair at last? (5)
I believe the answer is:
wheel
'vehicle' is the definition.
(wheel is a kind of vehicle)
'component needing tungsten repair at last?' is the wordplay.
I cannot quite understand how this works, but
'tungsten' could be 'w' (W is the chemical symbol for tungsten) and 'w' is present in the answer.
'repair' could be 'heel' (heeling is a kind of repairing) and 'heel' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for wheel that I've seen before include "Move in a circle" , "Circular object (in no need of re-invention!)" , "Rotating circular frame" , "Castor" , "Circular steering device" .)
