Depends on how well they fit, have had to use the vice at work with 2 plates of metal and some foam on 1 set of cups. And on my Robinson just a pair of quick clamps done the job, same with bearings into cups I have one that pushes in by hand and the other needs some help from the hammer. Might go to rOm tommorow(just got back,(the wifes camping)), if you dont make it and I see Rhys, I'll pick up his tool and get Caroline to drop it off as she only works round the corner to you Matt.
