Happy to share. The idea isn't original with me, I am sure, but it makes dealing with the brass on down the line so much nicer.
I bought my dehydrator for $5 bucks at ARC (I think). Turns out it's a $50 model from Wal-mart, but it holds the same amount of brass that the tumbler does, heats it to 160, and has a timer that I set for 2 hours.
My wife tolerates a lot from me, but I don't know that this would be approved...
