Also, if the hubs are sleeve type with journals - do not use bearing equipped end caps when truing and tensioning the wheels. You need to use a false sleeve with bearings to mount in truing stand when truing/tensioning.
If you try to use end caps alone like you might do with over sized hollow axle disc setups - you'll end up truing the hub - not the rim. One result will be extremely high tension on several spokes and the opposite on others as well.
