It was Dollar General. I think. We have three different dollar stores in town, and I forget which is which.
No, wait, it was Dollar Tree. Dollar general had the same pans for $3 each.
I decided to use screws or a snap ring, because one of my prototypes flew off in a test run at about 70mph, so there isn't quite enough sticking force with three magnets, at least in the setup that I have.
Remember that with magnets, the force falls off very quickly with distance, so when they start to pull loose, they let go completely in a heartbeat.
