Hey Daniel, honestly, I am not thrilled with the iron bands on the tracks. Technically I don't have to, and it does look good, but...Iron bands on tracks were used only on fortified places, where those cannons were removed from ships and assigned to lands.
Iron bands would destroy the wooden deck after a few tens of recoils, however in the land surface, without the iron bands, the trucks would be destroyed after a few hundred shots.
What you can do to dress up, is to make the iron bands for the axletree ends. Same techniques but the smaller diameter of the srinktube.
But the choice is only yours, what you will decide - would be correct..., for your model!
