Hopper Ideas

As the season approaches I am trying to think of a new hopper design for my EFM 520. I have used 55 gallon metal bins and 60 gallon trash cans. They both worked OK but the metal would eventually rust (wet basement) and the plastic trash can had too much static and the coal would bunch up. Anyone have any cool hopper designs? Thinking about making one out of pallets and plywood. Trying to think of something that tapers but still holds a lot. Thanks!

I have a ground wire on my dust system in the workshop for static control, would that work for your plastic barrel?
