Desperate!! Stuck on three; all intersecting. 22d. Panic when fuel is spilled in bed (4,4). _ _ _E _ _ _ K. Have tried fuel letters in bunk and sack. 24ac. Something to be heaved across Pole, not river? (6). _ _ _ I _ H. Second letter = second letter in 22d. 34ac One can start to unfasten wheels (4) _ _ N _ if 31d is anglers thumb. First letter = 6th letter of 22d.
Many thanks to you all. Believe it or not, I had unit and sleigh on my list of probables but couldn't quite fit them to the clues. All is now clear!!! Mind you, there are a few answers in this crossword that I still can't understand even though they must be right; including "anglers thumb". Many thanks again.
Yes, I realised "anglers thumb" was wrong when I inserted "unit". I got in such a mess with that clue (and others!) that I took "fish" as angle, rs as runners (why? I hear you ask!!) and "thumb" as finger. To make matters worse I googled to a site entitled "anglers thumb" and, although it bore no resemblance to the clue, desperation set in! I actually thought I had cracked it by default!! Just another bad day at the office!! Many thanks once again.
22d Blue funk (fuel in bunk, scrambled)
34ac Unit: unit = one; can = tin; start to unfasten = u, gives tinu; wheels means turn it round.
31d: millers thumb, alt name for a small fish (aka bullhead). finger = thumb; trampled on = below; runners = milers; crossing line = millers.
24ac: Got _L_I_H. All I can think of is SLEIGH, but can't match it to the clue.
