Let me clarify something he


The
"set" actually is accomplished by quick cooling after the feed is
straightened while hot, usually by dunking right into cold water.

What I should have said was that the "set" is accomplished by quick
cooling as you hold the still-hot feed in its re-straightened condition
while dunking it into cold water. While still holding the feed re-bent,
keep it in the water for 10 or more seconds, then pull it out. It should
"remember" the position you held it in when it was hot.
