In the recent "Home Shop Machinist" there was an article on a suposited better way of mixing flux with the allow. It looked like a bell with holes near the top. It was my understanding of the article that the flux was put inside cone and then it was pushed to bottom of pot and worked up and down like a plunger. The intent was to get the flux mixed with the alloy even at the bottom of the pot. Has anyone tried this method and does it really work?
