#97 coal elevator parts

give Jeff a call, he'll help you figure it out.

I found that #97 coal elevators would jam if some of the "coal" bits were too fine.

Yes, that will happen, CW.  Some years ago I switched to a larger coal, and it hasn't really helped.  Among the possibilities, I'm wondering if perhaps the chain has stretched a bit over the last 60 years hich allows it to catch coal behind the sprocket.

I have the machine on my workbench again, and made an interesting discovery.  It appears larger chunks of coal may catch between a bucket and the bottom scoop, jamming the mechanism.  I, like CW, had gone to a larger coal to avoid having it jam between the sprocket and the chain.  A finer coal seems to work better, but the fines may be a problem/ Also, I found one of the buckets is so tight on the chain that it can't flex enough so that one side can lift up over a lump of coal.
