G.T. Snail drum arrived - what does it fit?

Did you not get an English translation copy of the original manual in the box from Numrich?

Yes I did, but as I recall it only shows the drum apart, not how to get it apart. But maybe I just need to look more closely. It will be interesting to see exactly what is going on inside, hopefully that will help me know better how to get it settled after loading and to operate reliably.
