Can anyone help me with the below crypitic clues:
10D Must be well wound up to do anything (9) ( - U - O - A - - -)
20A Small vehicle contained within another, perhaps in space (3)
(2nd to last in 10D is 2nd letter in 20A)
19A Abiding or for as long as required or longer (9) ( - - - T - - - L - )
18D Not good at all, goes much further in short (3)
(2nd letter in 19A is second in 18D)
13D His job to pander to the master's whim and write a verse about it (7) ( - E - V - - -)
(2nd to last in 13D is 6th in 19A)
