Thanks. If you are confident with a welder then there's not much to it really. First off i put wheels in the lathe and cut off the outer rim with the part off tool.I obtained some inch and a half stock and had them rolled into round bands that were roughly the right size then tack welded them in place. When i was sure they were all in the right place i welded them up.Mig on the inside then tigged the visible join.
