Progress on the Annealing Front

[Wheres-Waldo]

I've been using an induction unit to do all of my annealing since I started messing around with it. Usually I'm not the kind of reloader who cares what my loads look like as long as they perform well. This usually meant clean but dull brass as I ultrasonic clean, no tumbling. I had a gentleman I work with tumble the shit out of some old brass I'm resorting. After annealing like Ive always done, instead of a shitty looking faint dark red hue, I get this very Lapua-esque show line and purplish color. I was planning on building a conventional annealer but I may not have to fix what ain't broken!

If you're not happy with how your annealed cases look, try tumbling them until they would give Blackbeard a hard on and see where that gets you...

What is the duration per case when induction annealing?

I have wanted to automate the induction annealer. I'm working on the automation now, work has me buried but hopefully this summer I will have it done. What induction unit are you using?

It depends on the size of the case.
I do a 25 second continuous ON to warm up the coil, then anywhere from 4-7 seconds depending on the wall thickness of the neck/shoulder. It also depends on the rate at which you are cycling the annealer. If your time between cycles varies by 10+ seconds (rough estimate) you won't get up to temp. If you speed your cycle time way up though, you can cook them to a faint glow pretty easily.
