I’ve been struggling with using my jointer since getting it, I’m hoping you all can help!
I’ve got a 6” Jet JJ-6CS jointer, and I’m pretty sure it’s tuned properly. I’ve got the height of the outfeed table set to the height of the blades at the top of their arc, the gibs have been adjusted to make sure that the infeed and outfeed tables are parallel, the fence is square to the table, and I’ve got it set to make a 1/32” cut for the most part.
The problem is that as I feed stock (primarily edges, I haven’t tackled face-jointing yet!) through, I get about a 3 to 4” cut on the front, but as I continue to feed it through, applying pressure to maintain contact with the infeed table, the leading edge tends to lift up off the outfeed table, often by as much as 1/8 – 3/16 of an inch. If I apply downward pressure to the outfeed side to keep the stock flat there, it simply raises the infeed side to the point where I’m not getting any cuts.
I’ve tried to keep consistent pressure on both sides, one or the other, directly above the cutterhead, heavy pressure, light pressure, etc, and even when I do get consistent cutting along the entire edge, (usually with softer woods like pine/poplar) I end up with significant snipe along the leading edge.
Help? What am I doing wrong here? I’ve never actually seen a jointer in use, (other than on shows like New Yankee Workshop, The American Woodshop, or the Woodwhisperer) so I haven’t been taught how to properly use it.
