Not as grim as last week but still some horrible obscurities. What's worst about them is that the clues are anagrams, which you cannot possibly solve if you've never heard of the answer. Last week an anagram produced the answer Et In Arcadia Ego, this week we've got:
2d Great chap frantically securing ends of uncut thermoplastic (5-6).
The parsing makes it obvious that this is an anagram of 'great chap' and 'ut' but unless you know much about thermoplastics you've got no way of solving it apart from sticking the letters into an anagram solver, which sucks the joy out of the crossword.
