Homemade Wooden Clamp





Introduction: Homemade Wooden Clamp

In this Instructable I want to show you how to make a cheap and effective wooden clamp. I have used wood chips and other materials that I already had in my workshop. As at first sight it may seem weak, this clamp has plenty of clamping pressure. It has a Norwegian style, as these type of clamping tool was traditionally used for Norwegian boat construction

I would also apologise for my English as a non-native English speaker some terms are very difficult for me.

Forward, inscrutable!!

Step 1: Materials and Tools


  • Elondo (African wood) & haya wood (Fagus grandifolia)
  • Spring ( 4cm x 0.10cm)
  • Hinge
  • Metal sheet (8cm x 1cm x 0.2cm)
  • Screws (3,5cm x 0.4cm)
  • Leather
  • Aluminum tubes (2,5cm x 0,6cm)


    • Fret saw (4cm)
    • Electric drill and hand drill
    • Bit drill ( 6mm&10mm)
    • Rasp half round
    • Steel Rasp File
    • Block Plane Stanley
    • Scraper
    • Sanding Paper grit 250
    • Screwdriver
    • Wooden clamp
    • Chisel
    • Engineers Square
    • Soft-Faced Hammers
    • Pencil
    • Saw metal
    • Hole saw

    Step 2: Cutting the Main Pieces

    I start cutting the pieces that I previously drew by hand and later I glue it on the wood. For cutting I use a fret sawl and for the rounded zone I use a hole saw.

    I use a rasp half round and a block plane to flatten the irregular surfaces and for the final touch a sanding paper grit 250.

    Here is thedrawing of the figure.

    Step 3: Joining Pieces

    For the join of the both pieces I use a hinge the most similar to the thickness of the wood and before screwing I drill the holes with a hand drill that afterwards I tightly screw.

    As the hinge I used is wider I polish the sides to adjust it to the maximum.

    Step 4: Clamping System

    I use other type of wood for making a color-contrasting for the clamping system.

    With the same hole saw I used previously I make a circle and after I use a homemade but very effective technique to polish it: it is about using a plane wood as a lathe with the help of a drill as you can see in the photos.

    Then we drill the wood in order to insert the wooden stick that we will use to tight the clamp. For this I use a bit drill of the same size of the wooden stick and finally we cover with another little stick the hole that remains in the center of the circle.

    Step 5: Spring

    For making the clamp return to the open position I settle one spring making 2 holes where this is accommodate without the need of any supporting system.

    Step 6: Metal Sheets and Aluminum Tubes

    Now we have to mark the points for the 2 aluminum tubes and we drill it with a bit drill of the same size (6mm) and then we introduce them in the holes. Afterward, we cut 2 metal sheets (8x1x0,2cm) and we drill one hole in each end with the same size of the tube diameter (6mm).

    I use a steal rasp file and sanding paper for a better shape and softness of the metal sheets.

    Step 7: Leather Friction

    I screw a piece of leather on the curve area for making strong friction against the wood as braking mode.

    Step 8: Final Assembling

    After a coat of oil onto all the pieces we start with the final assembling!

    For this the images almost speak for themselves!

      Very nice! I like how wooden clamps on wood seem to work better than metal on wood. Well, unless you are forcing the wood to do something it shouldn't.

      Veldig fint! Definitely a Scandinavian, almost sensual, shape.

      I will attempt to make a few out of, more readily available in Canada,hard maple.

      One improvement I will try is to make a couple of more holes in the aluminum bars in order to vary the grip range. And now I know what to do with that old leather belt (a bit too short now) I have been saving.

      It's a good idea what you propose as improvement. I would love to show me your final result. Thanks for the comment!

      I am having difficulty reproducing the shapes from the photos. I suppose a DWG file of the outlines would be too much to ask, but perhaps you could include a sketch on a 1cm.x1cm. grid.

      It's a very useful tool. Your hand-made tools are an inspiration.

      Great little project and well presented. Think this is a great project for a rainy day. Thanks I love the simplicity and using power tools it could be completed in no time at all with a useful tool at the end.

      It is the roller and its set position, I think, makes it remain close and decides the pressure

      what keeps the clamp closed? otherwise, very nice!

      1 reply

      The friction of the wood against the leather. I can assure that the clamping pressure is very high. Thanks for the comment.

      An elegant little clamp, I'll pass this on to my boys too.
