I purchased the adjustable height base to go with mine, you will need some way to adjust the height of the coil over whatever you are using to hold your brass cases to get the anneal where you want it.
Sacrifice a few cases, mark them so you don't reload them, and use them to set your anneal time. I use Tempilac {spelling?) paint, 450, 750, and 1000. I run 4-5 cases to get the unit warmed up and then test with the tempilac. You can paint the outside of the cases using electrical induction. As soon as the paint melts and turns color it has reached temp. The neck will always get hotter because it is thinner. It's OK if it just starts to glow for a fraction of a second. Top of the necks get to 1000 degrees on mine and they are still not too soft. If you make a drop box, and you will, production will become very fast, and that will raise the working temp. of the unit, and you will have to re-adjust accordingly. You will notice the necks glowing too red and too long. Just test the neck hardness and you will know they are too soft. Don't worry, they are not ruined. Turn the timer down a bit and retest.
If you get a few too soft while testing and developing a production routine, just set them aside, and later lube the necks well, expand them with a mandrel, resize them back again, and they will harden up again.
When I get the results I want, I take notes, record the settings, brass type, etc., wipe off the Tempilac, store the marked test cases, in something for the next time. Mark them well and do not reload them.
Once you get the routine down for each cartridge and brand of case and the notes taken, consistency will become repeatable.
Good luck, let us know how it goes.
