I get mine as close as I can with out machining, my knife's are with in a .001 and the beds are close to the same, I do have about .003 difference in front to back outfeed table height, and I'll correct that to with in .001 this winter, personally I'll spend better part of a day making sure the jointer, planer and Tablesaw are as close as I can get.
But I enjoy making things right.
Some figure if the tool doesn't fall over its close enough, some drag pieces over to the mill, ya just gotta figure where between the two your most comfortable, after all your the one using it.
