Avez-vous vu ces blocs de serrage universels en aluminium sur le marché ? Avez-vous également vu le prix ?

J’ai décidé de fabriquer les miens !

Did you see those aluminum universal clamping blocks on the market ? Have you also seen the price ?

I decided to make my own !

Je divise cette planche de chêne de 1/2″ X 5″ X 20″ (12mm X 13 cm X 52 cm) en quatre parties égales.

I divide this 1/2″ X 5″ X 20″ (12mm X 13 cm X 52 cm) oak board in four equal parts.

Je trace l’emplacement d’une rainure arrondie à environ 1″ (2.5 cm) de chaque section.

I trace the location for a round dado about 1″ (2.5 cm) from each section.

Je fais les rainures arrondies à la table à toupie (défonceuse) en utilisant mon chariot polyvalent maison et une fraise à bout arrondi de 1″ (2.5 cm) de diamètre laquelle correspond aux goujons (tourillons) du même diamètre que j’utiliserai à la prochaine étape.

I make the rounded slots at the router table using my homemade versatile sled and a 1″ (2.5 cm) round nose bit corresponding to the same diameter dowel I will use in the next step.

Cette butée permet de ne pas endommager mon guide.

This stop block prevents from cutting into my fence.

J’étends la colle, enlève l’excédent avec une paille de plastique et laisse sécher. Vous comprendrez que les rainures arrondies offrent une plus grande surface de colle !

I spread the glue, remove the excess with a plastic straw and let dry. You will understand that round dadoes offer a larger glue surface !

Une fois la colle sèche, je coupe la planche en trois parties égales.

Once the glue dry, I rip the board in three equal parts.

Finalement, je coupe chaque pièce près du goujon.

Finally, I cut each piece close to the dowel.

Voici quelques exemples de joints qui seront plus faciles à assembler. À noter que la pression de serrage doit dans tous les cas être appliquée centrée et perpendiculaire au joint.

Here are few joint samples that will be easier to assemble. Take note that in all cases the clamping pressure must be applied centered and perpendicular to the joint.

J’ai ensuite percé chaque pièce et arrondi une extrémité, tel que montré.

Then I drilled each piece and rounder over one end, as shown.

Ainsi chaque pièce peut être utilisée comme bride de retenue, conjointement avec les rails d’aluminium, comme le modèle du commerce du haut de la photo.

Doing so, each piece can be used as hold-down clamp, in conjunction with an aluminum T-track, as per the store bought model shown at the top of the photo.

    This is a brilliant idea. I too have thouhgt about the expense of the retail items which do the same job.
    Thank you for the idea I shall be making some of these in exctly the same way as yourself.

  2. luiessir says:

    ¡Buenisima idea!.
    ¡Very good idea!.
    ¡Muchas gracias!.

  3. Roger says:

    good stuff Serge. I’d glue a piece of sandpaper on the bottoms to be sure they didn’t slip while clamping.

  4. Eric R says:

    These are a very big shop helpers and really come in handy.
    Thanks Serge.
    You are the master.

  5. BRAVO! Another well-thought-out and presented work. I am truly in awe of your practical creativity.
    Thank you for sharing these.

    Great Idea! thanks

    I bought a couple of those aluminum ones, made some others from wood just for 45 degree joints and considered doing as you did for the odd-angles. However, I thought I would have flattened the surface of the dowel instead of cutting out a groove. While it makes, as you say, “more glue surface,” you start to introduce end-grain and short-grain into your glue joint. But you do have a mechanical shoulder. I was also thinking of countersinking one or two screws from the bottom. Do you think your way or mine would actually be stronger?

    And as always, thanks for your creative genius.

    • Keith, Since PVA glue is stronger than the wood itself, I’m faithful that neither of our jointing methods would fail. I’d also say that adding screws would be overkill. Maybe you should wait until one brakes, if it appends, to think about adding screws. We, woodworkers, often add more than required, right ?

      Best,

      • KeithM says:

        True, true. PVA glues, properly applied, have over 3000 psi shear strength. We used to joke when I was a design engineer “If it’s worth building, it’s worth over-building.” Thanks for your response.

        I do not have a core box bit in the size I’d need, which I guess is why I thought of flattening the side of the dowel.
        .

        • Keith, With this jig (Table Saw Cove Cutting Jig), and a little bit of patience, you can achieve the same results, nice cove dadoes.
          Oops ! Another way would be using a 1″ straight router bit and make the cove dado across each individual clamp by pushing it onto the spinning bit, on edge.

          Best,

    Hey Serge, did you have any of the dowels pop off if you used a lot of pressure. I love the idea!

    • Hi Morgan,
      I never used a lot of pressure, and I quite sure they will never pop off. PVA glue is so strong as well as the oak fibers.
      You love the idea ? Since the idea is from me, I believe you love me too !!! (ha! ha! ha!)
      Best,
