The fourth and final powered mechanism is working. A jam up in one of the motor driven mechanisms will be detected with current monitoring. I'll send the most current version. Even took it to the Hostlers big show in Odgen UT last week. Ran it continuously all day on a ni-cad battery.
Work continues on the rest to increase reliability.
Today, we commissioned service with the new dumper. THE ORE was difficult to find. Many materials were explored to simulate the Mithril ore. I felt that the rock products might cause excessive erosion and the dust could clog the clamping mechanism. The ultimate answer was crushed and screened walnut shells used to polish brass.
