I have a pair of tubular rims, laced to old Campagnolo Record hubs (the ones with the oil hole).

I would like to switch these over to clincher rims, but I have no idea where to start, or what I'd need.

Plenty of videos online to give you an idea of the effort involved. If you want it done soonish, probably better to pony up than DIY. Maybe talk to Arup?

If it's more of a project: decide what rims and lacing pattern you want, do the spoke calcs and buy the stuff. A stand, tension meter and a dishing tool will come in handy but you can do it on feel if you want. The results may not be so good the first time though...
