 Back in December of 1979. I had published an article in railroad model craftsmen about the construction of a rotary dumper I had seen an ad in the railway age magazine back in the 70s and This rotary dumper looked like it was easily modeled and made to work in HO and I've been able to do that so this dumper has been working for over three decades now and Now I use jam or I to control it. So I'll show you how that's done But first I want to just show you The dumper in operation. I have the dumper controlled now by a Lens decoder with back EMF And I have a flat speed table programmed in so going up or down whether it's loaded or unloaded It's like cruise control. It works very well much easier than using diodes and resistors under DC Since the dumper is controlled by that locomotive decoder It can be controlled by jam or I as well And I was going to put a couple of switches over here on the fascia of the layout and control it And then I thought wait, I've got a control panel here on the tablet that can do this And so here I'll tilt this up. This is a 10 inch tablet and it's showing you the Quaker junction panel here and what I've got down at the bottom of the panel are a couple of switches and Those switches control the rotary dumper. So Touching this switch here shuts off the dumper basically shutting down the locomotive turning out Functions two and three which are blinking lights and the headlight And so when I turn it on We'll get lights blinking on the dumper and I'll show you that in a moment and then to run it up You just hit the hit the up button and the dumper starts up locomotives in forward hit the switch the other way and the Locomotive or the dumper goes back in reverse and goes back down to the lower position Of course, I have lowers and upper limit switches on the dumper to limit the travel So when I turn the locomotive on or turn the decoder on You got the flashing lights on either side of the dumper to you know warn Operators in the area that the dumper is alive and in the back I don't know if you can see but there's a headlight that's come on It's in the lower position when we go to turn it to the upper position the headlight goes to the Opposite direction so you can kind of see that so we'll move a car up in the position here and do another operation of the dumper Cars in position start to dump her up so there's lots of things you can do with Jammer I and the panel pro editor and editors Use your imagination
