wood joint gap fill trick

wood joint gap fill trick


On just about every project
that I ever built there’s some joint that’s got
some gap in it. And that’s really
embarrassing so here’s my trick for hiding that. I start by squeezing a
bit of glue into it. And next I rub the
glue off with sawdust. And then sand it a bit. And now that joint looks
like it was precisely made.

  1. Do you ever have problems with that spot not taking stain because of the glue?  Thanks for all your videos!  Really appreciate it!

  2. Hey Matthias, I think you've shown us this in a previous video, but now that you've addressed it directly, I can ask, Can this be used to create an intentional effect of like two dark woods, with a lighter wood fill (or vice versa)? What do you think of the aesthetics of a piece done that way?

  3. I use that trick regularly. That's generally because you could fit a lot more than a piece of paper in my joints. I wish I could my work looking that.

  4. Matthias, I have been using this trick ever since I first saw you do it (LONG time ago).
    The only issue I've run into is when it comes time to stain.
    As you know, glue doesn't take stain, so there will be white blotches where the glue was used.

    Great trick, though

  5. If you don't have any/enough saw dust to hand, you can also apply the glue then snad the joint straight away while the glue is still wet. The glue clags up in the sandpaper and some ends up drying then rubbing off, but then a critical point is reached where the glue sets up with the sawdust you're creating, then it's sanded smooth and you end up with a perfect joint.

  6. Yes, Matthias, a good trick – you just have to remember not to do what I did which was to clean it up with a vacuum before the glue was dry…

  7. Simple it maybe but if you then try and stain or even varnish the piece, that filler will jump out and look awful. Clearly if you are painting, then it works well.

  8. I used to find that a drop of super glue (CA glue) and a few shavings from a scraper worked well as sawdust could sometimes turn black once a finish had been applied.

  9. To Answer Bob's question / statement below about staining or varnish, if you use liquid hide glue that does not happen. I keep a small bottle of titebond LHG in my shop for that reason.

  10. Ахуительный способ! Скоро будут видео – как забить гвоздь в доску.  

  11. I prefer to mix a very fine sanding dust with the glue then apply it to the joint with a putty knife or wood scrap, it worked well for me. Saves a bit on waste but does add another process (sanding after it cures). Good method for a fast patch though.

  12. Sealer mixed with sawdust is actually a better fix. Sealer dries clear and won't affect the woods ability to take stain.

  13. It's also possible to mix up a load of fine dust in PVA glue to form a putty that can be wedged into gaps.  Depending on the wood dust used the dry colour may vary from the original stock.

  14. C'est vraiment très bien mais assez coûteux pour un petit bricoleur mais je je suis très fans de Mathias wandel

  15. I do this in my screw holes. The glue mixed with wood duster make it very very solid hard. But it's done in old wood. Really old and very heavy and durable. I love the massive solid old wood. So hard it seems metal.

  16. Even though I'm a big fan, on this one I'm sorry but I have to disagree.
    Glue will interfere with stain and sawdust saturated with glue is no different.
    A much better way is to insert a sliver of wood with the grain oriented the same way.
    If care is taken, the resulting "glueline" is practically invisible.
    I've done this many times to fill in dovetail and box joint gaps and it works great.
    Also, using cyanoacrylate glue won't interfere with stains as much.

  17. I just started my woodworking channel and would really appreciate some feedback! I'm 15 years old and hoping to make projects in an easy to learn manner without expensive tools. Thank you!

  18. A few drops of lime or lemon juice on the mix of glue and sawdust will prevent the filler from turning darker than the wood.

  19. I collect the end grain dust when I hollow with a Forstner bit on the lathe.  If you intentionally cut slowly, you can make very fine and fairly even dust that way.  For small gaps I dry-rub some into the crack then wet it with thin CA glue.  Give it a few minutes and sand or plane it smooth.  Works well and takes finish pretty well, though I wouldn't use this method on a piece of fine furniture.

  20. Was the piece with which you demonstrated this trick just a demonstration piece, or is it another project that we will perhaps get a full video of at some later time? (There may have already been a video and I just don't recognize the project, although I don't think that's so.)

  21. Thanks @Matthias Wandel .  I saw you point this out in another video and have been using it ever since (more often than I'd wish lol).

  22. Any thing I ever built like that has such big gaps that you could bang a wedge into it, never mind saw dust. I am very bad at wood work.

  23. I use a sharp hand plane at some point on just about every project I do. I always collect the curls. They are super useful for just this purpose. Slide them into the gap and boom done. Plus, you don't have to worry about the stain vs glue issue everyone who watched this is probably worrying about.

  24. Hi good morning im from yucatan, Mexico and i Want to ask you how i can re sharp my forstner bit, thats because in my town its a very new ítem. I hope you can help me.

  25. Вообще пылью это лучше делается . Абсолютно бесполезное видео от такого профи как вы Матиас (

  26. But how often do you have an untreated wood furniture? Probably never which makes the job much complex because you need to repaint the whole piece (otherwise it looks bad).

  27. Good tip that I had forgotten about! was taught this by an old carpenter when I was a kid! Thanks for reminding me of it!

  28. Measure twice, cut once.
    Don't use a pencil to mark, use a knife.
    Mark the side you want to cut.
    Use the right tools, and sharp ones.

    And you have the best trick for filling gaps.

  29. Our shop teacher used to give us shit for doing it like that. He wanted us to make little tiny wedges to fit in the gaps, then cut them off with a flush cutting saw.

  30. build up a supply with fine sawdust and store in coffee can with lid. i think better than commercial products being organic to the wood.

  31. I was thinking about doing just this thing with some glued shelving. The saw dust I'm saving is accumulating in the orbital sander. Although you didn't mention it, do you allow the glue to fully dry before sanding? I assume yes.

  32. Why not just cut precisely? Honestly I’m a bit embarrassed for you. Maybe pallet projects would be a better idea eh?
