David,
I love the action of that Wolverine coal loader with the Hafner gondola. Wonderful!
Did the black balls (coal) originally come with the Wolverine coal loader or did you substitute something else? If the latter, what specific brand, type and size of black balls did you use?
Why is the insert needed? Won't the black balls work without the insert installed?

Bob,
After purchasing a Wolverine Coal Loader I have learned a whole lot about marbles and how easy they jam. At first I thought that the concept was simple, get a bunch of marbles and dump them into the loader. I found that they either continuously jammed or let more than one marble out at one time. After studying the problem I found that 17mm marbles worked the best, however only 4 marbles lined up in a row in the trough of the loader would work. The insert I made would allow 9 marbles to line up in an even row (9 marbles will fill up the Hafner gondola). The side view of the diagram shows 8 marbles, but I found that one more could be added as long as it is added on top of the last row near the end.
Here is a photo and diagram of the insert.
