Anyone got a good technique/aid for putting freehubs with loose pawls back into the hub
Put the hub onto the freewheel rather than the freewheel onto the hub.
So, put the freewheel on the bench, or better still in the bench vice, pawl bit upwards. Fit springs and pawls. Hold it still, easier with the vice, and place the hub gently on the top of it. There is just enough room to get your fingers in to squeeze the pawls slightly, it is possible to do all three at once. Push down gently on the wheel and turn it slightly at the same time, when you fell it click push it all the way down.
Works for Hope hubs anyway, my CK ones are different.
