Recently, one of my fellow Texans accused us Americans of being whiners. Well, hopefully after you learn this procedure, you will have one less thing to whine about. Namely, “I can’t surface wide boards because I only have a 6” jointer.”
You can surface a board approximately 11 ¼” wide on a 6” jointer, or up to twice as wide as your jointer, minus about ¼” for overlap. This is done by making two passes over the cutter head. The first pass will surface one half of the board and the next the other. Of course, one of the passes will be against the gain, and it’s best to make this pass first. Feed the board very slowly when going against the grain, especially at the end of the cut.
I didn’t have a 12” board for a demo, so I’ll use one that’s a little over 8”.
The board I’m using has a little bit of a bow and a little bit of wind.
The procedure for planing a wide board is the same as for one that’s a normal size for your jointer. Place the paddles on the low corners. Do not apply very much pressure on the front paddle, since there is not going to be any cutting done on this pass. (For this board).
As you get the board trued up, you will notice that you have a ridge line where the cuts have overlapped. If you’re not taking too deep a cut on each pass, this will not effect the over all flatness of the board.
You can take a card scraper and remove the small amount of unevenness.
And as you can see, the board is flat in all directions and ready to be run through the planer to true up the other side. This board will finish out at about 7/8” thick after planing both sides.
So, get yourself a stack of practice boards and go try this out. It won’t take long for you to get the hang of it. And then you’ll have one less thing to whine about. Wouldn’t do any good anyway. Your wife is not going to let you spend $2000 on that 12” jointer, so make the best of what you have.
