I'm curious - I read the posting about the person having trouble with his Hammer jointer/planer tables being out of whack.
The point that was mentioned in passing was about the floor the machine stands on being flat or level. That's my interest.
How important is it that the floor the Hammer or Felder jointer/planer stands on be flat and/or level? My concern with this is that I want one of those machines but I know with certainty that my shop floor, the basement of my house, is anything but flat or level. This hasn't been a problem with my DJ-20 jointer since that machine rests on top of a base which itself is on the welded steel mobile base.
Is the body of the Hammer jointer/planer sensitive to the floor not being flat? I can see that causing problems if the machine's cabinet twists or flexes in response to any dips or undulations in the floor.
