As for battery boxes, if they have the proper unvented lids on them water can not get into them unless they are turned sideways. This function is achieved by having a bubble of air trapped under the battery box lid. If it remains reasonably horizontal, it will also prevent water ingress to the box itself as the bubble extends down below the lip of the box. Standard Battery Box

anyone know of a way of 'snapping on' a pulley wheel to a shaft, i.e. is a pulley in 2 halves available?
