  • Mann's Creek hopper, ITS ALIVE!!!!!

    Now I know how Frankenstine felt when his monster sat up. I did some searching on the internet and found a site called www.hobbyengineering.com that had a small right angle motor and gear box that would fit in my Mann's Creek hopper like it was designed for it. The cool thing about the drive is that it has a "clutch" in it which works great because all I had to do was add start and stop pins to control the amount of rotation I needed to open the doors and the gears and motor can keep going with out breaking or burning anything out. The other cool thing was that final output shaft is removable and solderable, which made adding the cam a dream.

    I used a Digitrax decoder to power the drive and added contacts to one set of trucks, if it proves difficult to make good contact to the rail I will add a second set of contacts to the other truck.

    To operate the car all I do is select the hopper car number (address) with my DT400, set the direction to forward and press the "+" button one time. When the hopper is unloaded I change the direction to reverse to close the doors, once the doors are closed I press the "-" button one time to return the motor to idle and I dispatch the car address.

    the cool thing is that the unloading tresstle can just be a static model.

    The car still has the test arms installed and I will have to come up with a nicer way to make the final arms. this car requires a lot of pivot in the arms in all directions so I will have to do something better than I am doing now. I would like to use some RC airplane ball joints but I don't know if they make them really small, I'll have to do some searching to see what is out there.

    I am so excited that this actually works! Now that I know what it takes to make the hopper work I can crank out a dozen of these guys. I had to do some hacking on some of the inside bracing which I will have to clean up and make look nice on this hopper.

    Here are the videos of it working.

    Man that is just too cool for words!!!! Once the hoppers are all weathered up and a train of about 10 of them are there, this is going to make it look so realistic! LOVE IT!!!!

      so far the real coal is doing a good job of automatic weathering

            That's amazin!!! Now all you need is a "vibrator" to shake the

            rails & get the balance of the coal out! Just like the real thing!

            Great engineering there!!!!

                Awesome! Not only is it a great design, it also functions smoothly.

                        That is really amazing!

                        Quick you better patent that design and sell it to Bachmann!

                        The only working hoppers I have seen have been tippers and they have been pushed from the side.

                        Now you just have to design a auto loader for the other end of the line.

                        Looking forward to more projects.

                            How bout the "Vibrator" from a old cell phone????....worth a shot....

                            Besides, y ou don't wanna shake the hopper so bad, it derails....
