10 across: Hawk or Magpie spun ball’s outside point to control ball… (askance) (7)
To control ball = dribble, but nothing else makes sense.
6 across: Revolutionary ran to embrace one Zeno disciple (5)
One Zeno disciple = stoic, or, more likely, Zeno disciple = stoic. The rest, though?
8 down: Twisted bachelor-ess action sequence in The Dish?
The Dish = casserole, and bachelor-ess without the b and h is an anagram of casserole, but how that all works is beyond me.
4 down: They are common students, wearing beanies (9)
Wearing beanies = ebeians, which leaves students = pl so that students, wearing beanies = plebeians = they are common, but why does students = pl?
22 across: In Sydney, train horse to drop tail after smack (7)
Google tells me that a tangara is a type of train used in Sydney (this should technically be a DA Teaching, but I don’t find it interesting enough to bother reporting), which makes In Sydney, train = tangara. Everything else, however, I can’t work out (although mustang = horse could have something to do with the explanation).
13 down: It is crazy, perhaps, for desktop to be clean (9)
To be clean = sanitised, but I can’t quite make out the rest.
