As mentioned some time ago I am building an unfinished Clayton and have started to build the trailer until the funds are right for building the boiler. I know there are other Clayton owners out there and I wondered if any one has used any other wheels rather than the rear wheels for the wagon. The reason for asking is the price of wheels and tyres. This retirement project has one or two costly parts to it. I suppose this is a sign of the times with all hobbies.
