pedal bushes, tube or not?

Yes, it is a good idea to put a crush tube in the bush. This allows you tighten the bolt up fully and still be able to rotate the bush on the crush tube. Otherwise you will have to only partially tighten the bolt and use a Nylock or similar - Although this works, it does not make the strucutre as stiff as it is when the bolt is fully tightened.
