Lego Bogie

I couldn't find anything like this so decided to have a go at adapting one to lego from a 1:32 model. I can't remember what size the axle needs to be, I found a nail from the hardware store with both ends cut off, cut to the right length makes an easy to obtain axle. Superglue one side onto the main bogie, put the assembled axles in and then glue the other side on.
