Find a bit of porridge in a crack in the hall stand (8)

'the hall stand' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'find a bit of porridge in a crack' is the wordplay.
'find' is an anagram indicator.
'bit' indicates taking the first letters (I've seen 'bit of' mean this).
'porridge' becomes 't' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
The initial letter of 'of' is 'o'.
'a'+'o'='ao'
'ao' is an anagram of 'oa'.
'oa'+'t'='oat'
'oat' put inside 'crack' is 'COATRACK'.

'in' acts as a link.
