I'm finding my x axis quite difficult to move, so much so that even the power feed bogs down a bit moving the table. I don't know how much resistance the power feed unit itself adds to cranking the handles, but this seems like it's far too much. I can't seem to locate the gib adjustment screws at all. I see the gib up under there, but how in the world do you adjust it?? I also think that someone clearly used grease in the zurks rather than oil; that could be part of the problem. I probably just need to pull the table off and clean it all up. But to spare me that battle- can anyone give me some info about gib adjustment? Thanks!
