Hi Scott,
I haven't tried to keep the power feeder upright to see how much it would get in the way.? I installed the lift assist which makes it easy to raise and lower the feeder.? I don't use the power feeder much because I also have an old unisaw with a power feeder that I use for ripping.? The power feeder doesn't impact the jointer/planer.? Brian uses the power feeder to joint his stock but I haven't tried that yet.? I'm not at the same location as my Felder so I can't take a proper pic of it but the attached pic may show the power feeder better.
