For any of you, who wondered what are those ribs on drum casing - those are reinforcing ribs, so the casing won't band under tension power of moving track.
Thanks for this info to fellow comrade on local forum.

And i continue with front sprockets.
Those are with interesting shape and given in two types, as you can see on second photo. So don't do a mistake and cut them all, you need only eight.













After assembling them i connected a little chain of tracks to see how it seets on sprocket - looks good.



Dry fitted them in place. Will glue in later stage, when chain will be put on.
