How to make a jointer out of an electric hand planer

Do it yourself jointer

Probably you already know that I don´t like my electric hand jointer at all. I don´t think it is safe and easy to joint wood with it. For me it is very difficult to flatten any piece of wood with it and I feel I would need a lot of practice to avoid cutting too much in some parts of my working piece, mainly in the head of the board.

The homemade jointer knifes must graze the board

Some people asked me how to attach it to a board, so I tried to work out how to do it to make a homemade jointer. Truth is it wasn’t very difficult to attach it to a plywood board and for me the final result is great. It is very easy to joint wood with it (I had never used a jointer before).


But keep fingers and clothes away from the blades!. This small homemade jointer won´t give you a second chance.

I think I won a very good tool to use in my shop. Well, actually I won two great tools, because we can use this as a thickness planer to adjust the thickness of our planks and slats. Yes, one can also make a cheap thickness planer with this do it yourself jointer.

The hole I made to attach the planer to the board

We need to make a hole in the board so that the blades and the metallic surface touch the plywood board. With a wooden block we must adjust the metallic base so that it is at a 90 degrees angle with the board. After all the work, it was easier than I thought It would be. It is just a question of being careful so that we don´t make a hole bigger than needed. The best way to make it is to rasp a bit the board and check the position. And the keep doing that until we have a perfect fit. Be patience and work calmly.

How to make a jointer from a hand held electric planer

You don´t need to carve the wooden block under the handle if you don´t want, just adapt it to the handle to adjust the position of the planer.

As you can see in the video, we adjust the wooden blocks so that the trigger will be always on. So it is very important to use it with a safety switch. I use the one I use with my homemade table saw.
