how to repair split cogs?

cheers, super. never would have thought of the c clamp. have asked ucwepn and he said super glue as well. will give it a go in a couple of weeks.

been on a repairing spree today. successfully got two merry-go zoo elephants working, and checked and lubed the rest of that range. also quietened down a rusty for my nephew.

just had another go at my japanese talking diesel 10 set, and got beyond annoyed with it. thought it was a split axle, nothing to be seen. no idea what the problem is, but ive had enough of it. makes it worse that the battery thing is in splatter, so all that extra weight to drag around, plus trying to hold things steady at the same time. grrrrrrrrrr. right now i couldnt care less about its rarity. about my most expensive piece, and the least useful.
