Edge of wheel following path round front of garden (6)
I believe the answer is:
flange
'edge of wheel' is the definition.
'following path round front of garden' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'path' becomes 'lane' (lane is a kind of path).
'round' indicates putting letters inside.
'front of garden' becomes 'g' (I can't justify this - if you can you should believe this answer much more).
'lane' placed around 'g' is 'lange'.
'f'+'lange'='FLANGE'
Can you help me to learn more?
(Other definitions for flange that I've seen before include "Projection used for attaching another object" , "Projecting (steel) collar" , "Raised edge of a wheel" , "Projecting rim or piece" , "Broad flat projecting rim" .)
