Woodworking connection goes once round a seedy bar (3-5)

'a seedy bar' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?

'woodworking connection goes once round' is the wordplay.
I cannot quite understand how this works, but
'connection' could be 'joint' (joint is a kind of connection) and 'joint' is found within the answer.
'round' could be 'lap' (as in a round or lap of a park) and 'lap' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
