I'll tell you one thing. Riveting isn't.
These pictures just shows the exteriors of the tracks--I had to do a bunch of riveting on the lower parts of the interiors of the tracks. I estimate there is something like 1,300 individual rivets on these pieces. The work isn't hard, it's just very tedious. In the end I think it's worth it, as the rivets add a lot to the model and make it look ten times better than if all the rivets were not there.
