Rotary Dumper

Modeling
#1

Anybody got good pictures or plans for 1/2" scale rotary dumper? My brother has a chubby for one of these but the processing plant that goes with it will be bigger than a garage.

Hi Mike -

No plans, but I have photos of one in HO from a show if that might help.

SEND THEM TO MY EMAIL. [email protected] Thanks

I’ll look for them this weekend and shoot you an email.

EDIT - They were easy to find. Strange. Email on it’s way to you.

You know … in that photo above:

The locomotive appears to be designed to run off of an overhead power source of one kind or another, but there are no wires for that purpose anywhere in the photo. It also appears to be capable of running from onboard batteries … but I was under the impression that locomotives so equipped were only really expected to do this for short periods of time. Anybody know what the usual range was on one of these things, or how this particular operation worked? I’m guessing it’s Monon from the photo name. Matthew (OV)

Years ago, I built a rotary dumper. It still exists, but needs more work. The weak point on mine was the clamping device.
The basic structure was made of steel. The two ends of the dumper proper, were cut from 1/8" steel plate. They are circles with the opening cut into them. They roll on two bearings at each end.
One day I should get it out and take a few photos. That might motivate me to try making it work again. It actually did work at one time. The main problem was that I tried controling it with a bit of automation, using micro switches, and they were always going out of adjustment. Then, one day a friend decided to try to improve it, and removed the chain drive, replacing it with a friction drive…not a wise move…

Mike,

There was a working G scale one

at the Fall ECLSTS last year.

I don’t know who the club was.
