My dictionary doesn’t think fettling is a word. It’s wrong.
Gary spends quite a bit of time fettling. It’s the present participle of the verb fettle and means sorting out, tidying up and tiddlying off.
Fettler is also in my dictionary. A fettler is a person who fettles.

Quite a bit of fettling of my stories is needed before I’m ready to submit them to magazines or enter them in competitions. I think it’s worth the effort.
