Talk:Sweet as a nut
From Wikipedia, the free encyclopedia
I believe this term comes from 18th century Britain during the industrial revolution. The term refers to the nuts (attached to bolts) on large steam boilers, that needed to be adjusted as the boiler was heated.
As the metals expanded at different rates the nuts that held the boiler together would need to be tightened (or sweetened) else the boiler could blow with tragic results. Some nuts would sometimes need five or six extra turns.
The nut was said too be sweet after it had been readjusted during the heating of the boiler. Comment added to article page on 19:29, 1 January 2006 by User:86.141.223.197. Steve block talk 22:11, 28 March 2006 (UTC)
