I am working on an automatic dumping system for the typical LGB tipper car. I remember a Youtube video where the tippers were pushed toward the unloading site, and a trackside ramp of sorts was used to lift an arm that was attached to the end of the tipper bucket. I can't seem to find that video. I was experimenting tonight with some stiff brass wire, and I must be missing something, besides my brain. Said it before you had the chance to. Does anyone recollect such a video?
