sorry, the faller axel is slightly to short
so i have to pop it off the faller axel, which i haven't been able to do so far, and slide it n the stock roco axel. that is the axel that one of the wheels has become wobbly.
i'm not oppossed to using a new, slightly larger diameter axel only i can't find steel rods that small, not to mention almost impossible to find metric stock anywhere.
i had an idea to use a new slightly larger diameter axel with threaded ends so i could screw on/off the wheels. but i can't find the materials and don't have the tools. any chance you have the ability to do this?
