I built this thing using a schematic cannon and the right brass funnel doesn't want to work at all. Yes and when built the first time, required the precise mechanisms I was going for with this same build. You had a simpler build in the video that appealed to me more than this one. And the link is pointed here. Unfortunately, one star :(
I've found an issue of brass funnels not working, had to rebuild vault inventories by myself so they all connected as supposed, good building
