how to repair split cogs?

[Super]

I think all the Train engines like the Disney steamers, Benkei, Yoshitsune and the others have a problem with splitting gears like that. It may be to the gears being plastic and not neoprene or how they are set up within the gear box, I don't know. I have had a couple with the same problem and I have bought junkers that didn't run for the original owners because of it. What I have done in the past is use Super or Krazy glue. The kind I like to use is the brush applicator style. The glue is thin enough not to build up in the gears and the brush is useful in getting the glue deep down to the axle and covering both sides of the split. Getting the glue to the axle bonds the gear to it along with both sides of the split adding more strength to the repair and to prevent slippage. I would recommend you stay away from the tube or thick Super glues as they may fill up the groove between the teeth. I then use a mini C clamp that should be available at a local hobby or hardware store. In a pinch a binder clip may work but I like the C clamps because you can control the pressure so you don't damage the gear. Good luck!

Thats what I have done but there may be others with a different way. Didn't Ucwepn repair a gear in one of his videos?
