[python] Re: brazing aluminum ??

The key is the melt point of the rod. They say there is no flux involved, it is 
a metallurgical trick containing nine different metal alloys. They say the melt 
point is c. 500 ° F lower than aluminum, that's what makes the thing they do 
with the pop can on the video possible. I wish I could borrow one of the 
airport fire dept.'s heat detectors to experiment with... Maybe sometime on 
night shift sometime next year. <shrug>

ron
