Having trouble parsing these, help much appreciated......
4a Coat bound to cover a hole, half reversed - ( 6) - MOHAIR (Coat)
I can see A HO)le) reversed, but how does RIM come from 'Bound to cover'?
26a Drained piping, distant or otherwise, in remote outlet (7,4) - TRADING POST (Remote outlet)
Literally cannot parse a single letter of this clue!
4d Club that's used in riot control (4) - MACE (Club)
This could almost be a straight definition, what is the cryptic relevance of 'Riot control'?
