Topic tags/keywords: planer joiner

I’m hoping someone can help me out.

I purchased some 4/4 oak. It is +7” wide. I have a 6” joiner. I would
normally square up 2 edges on the joiner and then plane to thickness.

Can I use a planer to square up the wide dimensions?
Are there inherent problems trying to do this?

I’m not skilled enough to do it with a hand plane. I cannot
purchase an 8” joiner

Thanks for any advice,

You can use your planer with a sled. My sled is two pieces of 3/4” mdf glued together to make a very rigid surface. Then all I do is use hot glue in a few spots to hold the board down on the sled and keep it in place. Run it through the planer until the top side is flat then take it off the sled, remove the glue, and run it through the planer to flatten the other side. I don’t have a jointer so this is how I do all my face jointing. It takes a while but works until I can afford a jointer. I think there is a trick to doing wider boards with a jointer but I don’t know.

What are you building? Does it require the 4/4, 7” wide board? I cut to rough size according to what I’m building and then mill the lumber. Of course, if you need the board the full size and have only a 6” jointer then some magic is required.

Remove the guard on your jointer, and make a pass or two until a ridge develops on the face of your board. Then place the board upside down on a strip of plywood. Overhang the rough part of the board, so the milled section of the board is flat on the plywood strip.
Now run the board and plywood strip through the planer. This will give you one flat face. Then simply flip the board over, and finish planing the other face as usual.
With a 6” jointer you can joint boards up to 9-10” wide with this technique.
