re: Don't do what I did

Bingo! on setting all cutters to same height. I am going to ADD “jointers” to this thread as well. My 8" jointer, with it’s 40-cutter spiral head can be a bear too. My biggest mistake with this jointer was trying to get TOO MUCH MILEAGE out of each cutter face (remembering that each carbide cutter has 4-sides).

Why is this a problem? Staying with one cutter face(#1-side) too long will make cutter faces #2 and #4 “narrower”, and this seems to now produce more very light lines on the wood being jointed. Not a major issue, but one has to remember that sanding then becomes a mandatory part of each jointed side. Much like having a couple of chips in your 3-blade planer that produces similar lines, but not as many as a spiral head IMO.
