Make homemade thickener.

How to make a thickness planer

As we are that we look with distrust who we do not know even if we get tired of seeing him in front of him every day. And is that sometimes you just have to be surprised. I already told you at the entrance of the homemade table brush that I had made peace with the electric toothbrush by being able to use it as a table brush. But this being able to use it also as a thicknesser ... I think I already have almost as much affection for it as I do for my milling machines. And I was thinking about where to get the minimum € 300 that a thicknesser is worth. Being able to brush and thicken the wood will save us money when buying the wood, since planed usually costs more than sawn. In addition, we can adjust it to the measurements we need better than with the table saw and we will save a lot of sanding time.

To make this homemade thickness planer I need the electric planer for wood attached to the table, as I showed in the post how I make a DIY jointer with the electric planer . And I also need my sliding fence.

Thicknesser and lateral guide.

The idea is to put the wood I want to thickness between the planer and the sliding fence, and thus I make all the necessary passes until I get the the wood to the size I want.

One can think that this could also be done using the jointer, but if the two opposite faces of the wood are not parallel, using the jointer we won't be able to leave them parallel, while with the thickness planer we can make both faces parallel.

Thicken ribbons.

If we have a perfectly flat face and the other we want to leave parallel to that, we put the flat one against the guide and brush. The planer blades will push the wood against the guide so that the planed side will be parallel to the guide and therefore to the other face of the wood. But for this to work the base of the brush and the guide must be perfectly at 90º with the table surface and the guide and the base of the brush must be perfectly parallel, so if you manufacture both, try to make the necessary adjustments.

In the video we see how the process is. Of course, I think we cannot trust the depth of brushing that the depth guide gives us. On my brush it seems to be half of what it marks. In any case, the trick is not to brush over.

And finally recommend that you connect the aspiration. The electric wood brush produces little sawdust but a lot of shavings. Failure to remove these can clog the machine's suction tube, causing chips to get between the blades and the wood. Having the guide will surely increase the pressure on the blade and it will be more difficult to push the wood. When brushing by hand this causes the brush to bounce and instead of being a smooth surface we are left with small ripples.

  1. I really liked your thicknesser. I was looking for an idea and I found it. The truth is that putting it vertically has been a discovery that greatly simplifies things and above all, gives security. Maybe I will make some small variant to simplify, since I will only use it for small things (naval modeling)
    In any case, thank you very much for your ideas.


    1. Hi, thanks for the comment. I do not know if it will serve you for those thin pieces that you use in modeling. Pushing them by hand without breaking them seems complicated. Another option is to use a narrow enough wooden pusher (if it is metal you run the risk of damaging the blades). I have an entrance where I make some wooden pushers to use with this thicknesser, take a look. Courage with the manufacture and I hope it will be very useful to you.


  2. Your idea of ​​vertical brush is very appreciated, practical, simple and above all, safe. I'm going to do it with a tiny brush and some small variation, trying to simplify, since I only work miniatures.

  3. Excellent idea.
    There is a big difference in the results when sliding the table on the machine, against the machine on the table. I would like to share my experience by sending you some photos of the construction of my thicknesser with some variations mainly in the approach guide, I would like you to see it and get your opinion; However, I cannot find a way to send you the photographs.

    Thanks for your ideas.

  4. Hello Sergio. Very good as always your contributions and ideas. Question: if the wood to be thickened is wider, how do you do? Do you pass it first on one side and then the other? It fits well? Sincerely. Daniel

    1. Hello Daniel. If one of the faces is completely flat, perhaps the other can be thickened in two passes and with a little sandpaper we can fix the remaining marks. But if neither side is completely flat, turning the wood to finish thickening the two thickest surfaces on the same face will probably not be on the same plane. The truth is that at the moment I did not have the case of having to thicken wood wider than my brush. Regards

  5. How about Sergio, from Montevideo Uruguay, to thank you for the material you send us, for me very important because I am an amateur and I find in your videos very valuable material. I hope you can continue these classes and continue acquiring knowledge to put into practice because they are very important. special greeting from a distance.

      Hello Roberto. I am glad that my videos are helpful, although keep in mind that I do not have carpentry studies. The things I do have been learned as I spent time on this hobby. I hope to continue making these carpentry videos for a long time 🙂 Greetings from Galicia, Spain
