About two seconds before the case drops you can see the color change of the brass and you can tell by the look of it before it falls that if it were to stay in the flame for another second or two more it would begin to glow. At the time the case drops there is no red, orange, or pink color to it, but you can tell that it is right near the verge when it drops from the flame.

Now I just need to make something to feed the shells from the hopper.


Annealing gun brass has to reach a temp 750-775F to be of any real benefit. Anything over 800F and the brass is junk and anything under is a waste of your time and efforts.

I like the way you have set your machine up. I think it will work very well. I like the idea of the cartridge sitting in one place -- one torch. I have to use 2 as the case moves.

Thanks Jerry. Of the two designs this one seemed the easiest for me to make. It feeds very well. I do need to get some indicator to get the temp right. I'll have to order some. Thanks for the link. I wasn't sure where to get it.

Here is a pic with the torch in place.
