Jointer technique

[lowell holmes]

That's why a thickness planer and a jointer sits in my. If the board is cupped, I joint the cup out and the plane it to thickness.

My planer is a Dewalt 734. It is mounted on a shop made table and I saved the carton with the styrofoam packing that came with it.
I cover the planer with the box and foam to protect it. It looks new and is at lest 10 years old.

Jack,

No, I didn't surface 4 faces on the jointer. As I mentioned, I understand that only the edge and flat would get jointed, the opposing edge and flat would be addressed on a table saw and planer.

My first attempt only surfaced the flat of a single board.

I will supply a picture of the offending piece this weekend (12-23-17)

Gerry,
Have you checked the machine alignment as I suggested?

The photos above are from opposite sides of the board I ran through my new jointer. The top of the board is what was run through the jointer.
Does this supply any clues as to what I might have done wrong?

Matt Day,

Not yet. Busy holiday season. See the photos I just added.

The top appears flat. If those thick corners are at opposite sides then the jointer is doing exactly what it should be and the board had a significant twist to it.

Gerry, not on the subject of your jointer technique question but on your post : I can commiserate on the attached thumbnail. I haven't found the way to remove an unintended photo attachment.

[Gerry S. Wojtowicz]

Thanks, Yonak. I didn't even notice it. Item recently sold on Ebay.

[Gerry S. Wojtowicz]

Thanks Brian. I didn't notice a twist.

Matt,
As nearly as I can tell the jointer is set up properly; the fence is perpendicular to the table; the outfeed table is parallel to the cutters; infeed and outfeed tables are coplanar. I think I just need practice.

[Brian Holcombe]

Thanks Brian. I didn't notice a twist.

Check both sides with winding sticks and that will tell you. The jointed side should be twist free and the opposing side should, in this case, have wind or twist to it.

[Matt Day]

Gerry,

Did you check those measurements with feeler gauges or by eye?

When you practice, start with all down pressure on the infeed table and begin pushing the board forward to the cutter head. After about 6” of the board gets across the cutter head, put a hand on the board on the outfeed table and apply pressure downward. When there’s enough room for both hands on the outfeed table, use both hands apply downward pressure and to feed the rest of the board.

Remember to never have your hands directly over the cutter head.

Plenty of YouTube videos out there on it. This one seems pretty good
