We have an instructable explaining how to build your own disc wheel. The disc wheel consists of an NC turned three-piece aluminium fixed-fixed hub, carbon fiber laminates and an aluminium clincher rim. The wheel is trued using conventional spokes and one of the carbon laminates is bonded to the hub flange and rim side wall. The spokes are cut off and a carbon laminate is bonded on the other side with four strips of PET foam acting as core material (optional). The foam could be left out since the laminates are quite stable. We use aerospace grade prepreg carbon to make the side plates.
