As I mentioned in my post the cans stick to the chute if I hold them against the outside of it .
The chute cover is sheet metal, but the chute itself is cast, and looks like zamac to me. I don't understand why they would stick.
If the cans are hanging up in the chute, I'd make certain the inside of the chute is clean, and has no burrs.
There is also the possibility that the cans you have are defective. I've seen the problem more in "O" gauge milk cans. Some cans would work, others not.
Maybe the cans are a little too tall, or the magnets are sticking out of the bottom. Maybe the grooves are in the wrong place, or aren't clean and smooth.
