Does anyone know anything about this Rivarossi loco (on the left)?
I seem to remember finding somewhere that it was one of Rivarossi's first American offerings, or something like that. All I really know is that it seems pretty chunky and toylike, and has a vagueley European outline still.
Also, would anyone know how to fix a wobbly drive axle (rear axle) on this engine? I think it's due to the plastic frame wearing out at the bearings, since the drivers seem to be perfectly quartered. (I'm willing to do some pretty extensive modding, if necessary, since it runs just fine other than waddling down the track...)
(Interesting note: the stack is a separate brass part, that the screw from the bottom of the frame fits into. Unscrewing the stack is necessary to take the loco apart from below.)

Thanks Ray...that's the website I remember, but I lost it somewhere. Now I just have to figure out how to make it run straight.

You could rebuild it with epoxy or scrap plastic, but in situations like this I prefer to work with CA. You can use CA and baking soda if the wear was extensive, or CA and kicker (sets it instantly) if there's less. Just put some CA in a plastic cap or lid, then use an unwound paper clip, a toothpick, or a section of scrap wire to carefully lay the CA down in the worn spots in small layers. Be careful where it runs, though, because it likes to travel. With baking soda, sprinkle a small amount over each wet coat, and it will harden instantly, then repeat until you have a rough profile, then file and shape as needed. You can also Dremel hardened CA and baking soda easily, which I did with this chipped cab roof to match the roofline.

Thanks for the tip...that sounds like it should do the trick. I've been looking for a method to fix this kind of problem for a while, since my tired old Model Power Pacific is starting to have the same wear after several million scale miles.
