"Looks pretty. Why aren't there any pics of it chopping wood? Even on the website. Having only 2-3 threads of those screws engaged is concerning.

"I think they solved this the right way, and that's to scale up labor as needed. The chute is genius. There may be other ideas similar to this scale and I'd love to see some in the comments.  If they rebuild the stadium someday, they may integrate radiant heat in the concrete (like in the streets and sidewalks of Holland, MI) or build a stadium with a roof (novel concept!). But for these rare events, just rally the mafia and get after it.  "
