I've used the 6 ton press for a few components now and can share my experience with it.
So far I've removed the front hub,gearbox fork smaller bush and installed the axle bearings (bronze ones not OEM).
I've found out that it doesn't require much effort once you position the component correctly, the hardest bit was infact trying to find a good position for the parts I needed to work on and make sure they were flat and not inclined with the press shaft and leave clearance for the bearing/bush to come out,you only get 2 steel plates about 5mm thick and about 10x5mm which I found weren't enough for the job so having additional plates and drift to push on the part to press out helps a lot.
Next I would like to try and press out the wishbone balljoint and bushes,will see how it goes.
