Can “stemwind” be used as a verb?
As FumbleFingers' comment suggests, stemwinder as a noun or adjective appears far more frequently than does stemwind as a verb. (Some noun and adjective examples appear in these discussions of the term stemwinder: Slate, 2004, refers to "Obama's stemwinder in Boston"; word-detective.com, 2011 mentions "a stemwinder in the old tradition from Hubert Humphrey"; worldwidewords.org, 2002, notes new sense of "long, interminable and boring"; theatlantic.com, 2000, delineates some variations like "a stemwinding speech" and "Ain't he a stem-winder?".)
When reading something a few weeks ago, I may have seen the term stem-winding applied to speeches that lay the groundwork for campaigns, plans, proposals, (that is, used in much the same way as the phrase "Winding the Clock") but have no reference for usage like that.
