Do you use a jointer on the face of a board or just the sides?

[Travis Conner]

Running a board through the planer seems to take out any warp on the face, but of course this still leaves the sides to be crooked

[Stan Calow]

Yes you joint a face so it is perpendicular to the jointed side. A planer will not flatten a face (without using a sled) it just makes the the two faces parallel - banana in, banana out.

[Matt Day]

Joint one face, joint one edge, plane opposite face, rip opposite edge on TS or plane it.

[Mike Kees]

The whole point of owning a jointer is to make a flat face with one square and straight edge. Matt describes the rest of the process to get to four square stock.

As mentioned, joining the face of a board is often the very first step in milling lumber. Remember FEE; faces, edges, ends

[Bill Dufour]

If you are gluing up pieces the two edges do not have to be parallel. just straight and perpendicular to the face . Once you have a panel glued up then you rip it parallel off one side. Of course if it is badly off parallel the clamps may slip but a few degrees degrees not matter until the final cut. After clamping I run one edge over the jointer to remove any clamp marks then rip the other edge to width.

I face joint on the jointer if necessary, but it isn't necessary for every board.

If the board will go through the planer without rocking, twisting, jumping, or deforming, it likely doesn't need to be face jointed, even if the surface is not completely flat. Before I got a larger jointer, I would hand plane wide boards flat enough for planing. I just got them flat enough for the bottom of the board to register property against the bottom of the planer and without any twist or rock.

Most of the "rough" lumber that I am getting these days seems like it it is coming from the mill skip planed through a two-sided planer. Often times, these boards do not require face jointing to be planed to final thickness, although often the wide boards may get a little cup that needs to be cleaned up.

I usually edge joint on the jointer, but only after the board has been planed and rough cut to length. I typically don't use that edge as the finished edge, but as a reference to rip the other side of the board. I rip to width after that. The reason is my table saw normally leaves a better finish than my jointer.

And if I get more than about 100 bd ft of anything, I cough up the $38 for S2S SL1E oversized by sixteenth or so :)

Joint one face, joint one edge, plane opposite face, rip opposite edge on TS or plane it.

This is the standard process for squaring up a board.

[Jim Becker]

The very first thing I do when processing lumber, other than rough cut to length, is face joint it followed by thicknessing. It's the only way to have flat material. I don't personally process edges on the jointer most of the time because straight line them on my slider, but that's also a normal application for the tool.

Same here.
