Hello again. I see the aforementioned model (which I just bought 2nd hand) has a habit of cracking around the lower chain casing, in this case its 'only' the rear axles. Whats the best way to fix this? I am going to take it to an engineer in town and see if he can make a plate up which can be welded onto the underside of the chassis and bent (correctly bent in a press) at 90 degrees up and around the axle housing. Has anyone got a better idea?
