Any thoughts on why my Jet 6" jointer is suddenly creating a SIDE TO SIDE
taper (on the width of the board, not the length)? It's impossible to get a
good face on a nearly flat piece of rough stock. Keeps cutting on one side,
gets thinner, and thinner. If I reverse the board, I get a high spot down
the middle. I've never seen this before.
I'm in the middle of replacing the blades and tuning up the alignments.
Figured I'd start there to make sure everything is right.
Sounds like the outfeed table is not parallel to the knives. Did you happen
to lift the jointer by the outfeed table and maybe pulled one gib up
slightly - just a few thousandths will do it. Make sure you can adjust both
the infeed and outfeed tables and that everything is in alignment as per the
From the sounds of it somehow you have gotten at least one blade higher on
one side (the side that is cutting) then the other. Remember, it only take
one of the blades to be out not necessarily all of them.
