DIY Annealer

 That is pretty cool , but how do they know what temperature the brass case is ? Under heating , it would not of done anything & over heating will make the brass brittle & useless . I see they have controls for what looks like speed , so they may have a timed temp. control . 

  I use a temperature marker so I can see when it changes color at the proper temperature range . I have found that all brass is not created equal , but maybe I'm just anal about it .

in the original instructions they show using a paint on temp indicator liquid  to use on an old cartridge case to set the speed of the main motor to get the correct annealing temp.

Correct. You put 750 degree tempalaq (it's a paste that melts at a certain degree) on a few cases inside the neck and when it melts you know it's at that temp. You just figure around how many seconds it takes and then set the drum to the correct speed so it holds the case that long before dropping it.
