I am not an expert on this, but I believe that you heat to a dull red to normalize. A bright red will anneal the steel which is not what you want. With my butt in the seat I would pay fifty bucks for my local heat treater to do it correctly unless I was 100% sure what I was doing.
Obviously the best way is to just buy the normalized steel and use a band saw, sander, and drill press, not you cutting torch or plasma cutter and you won't need to worry about having to re-normalize it when you are done.

You can do that by heating it to red and letting it aircool at room temperature same as you do with a cluster on a steel tube airframe _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
