You don't need a jointer to joint boards. If you already have one. Great. But there are several ways to joint board edges. You can joint with a table router. Actually this is not unlike a table jointer. Think of it as a jointer turned sideways. It works well but tuning in just the right offset is a wee bit finicky. You can joint on the tablesaw with a an adjustable sled. There are other ways as well.

Here's one I like because once it's done there's no more required.

You take your boards to be joined and create a consistent gap between them where the gap is less than the blade's kerf width. In this photo I placed a 3/32" thick piece of scrap between the edges to be jointed. My blade is1/8" thick. I then CA glue several "scrap holding pieces" across the board's tops to hold them. (You can see the gap spacer between the boards). NOTE: You only want a couple of CA dots. You'll be removing these after your cutting.

Now remove the space from between the boards.

Next... raise your blade height to come about halfway up on the CA glued "scrap holding pieces". Do not set your blade too high as you do not want to cut through the holding pieces. Next, move your fence so the blade is as dead on center as you can get it to the gap between the boards.

Turn your saw on and run it thru. Turn saw off.

Next knock off the CA glued screws holding pieces.

Your joint should look amazing!

Thanks for looking!

Cheers!

Usually...

Step #1: Peel one edge off with the rip fence rubbing along the better looking of the 2 edges

Step #2: flip/turn board over, move fence 1/8" closer to the blade...run the just peeled edge along the fence.

Step #3: Set the fence to the desired width the board is to be....Run the straightest edge along the fence...Edges should be, by now, parallel and straight...

BTW: Let said board sit a day or so after you've saw-jointed it...just in case the board wants to move a bit...VOE..

@MrRick Great idea. Thank you.

But I'm either confused with the 9/32" scrap for the gap, or I'm having a serious senior moment. That's wider than the blade.

Did you mean 3/32"?

Thank you @JimM Yes I meant 3/32". I've corrected it now.
