This article will be interesting to all masters working with wood, and not only.
In it, the author of the YouTube channel "Shaun Boyd" will tell you about a very simple way to tighten the corner joints.
Moreover, this technique is applicable for various angles, even more than 120 degrees.
Materials
- Board
- Plywood
- Dowels
- PVA glue
- Second glue
- Sandpaper.
Instruments, used by the author.
- clamps
- Band-saw
- Orbital sander
- Lamellar milling cutter
- Ruler, pencil.
Manufacturing process.
Perhaps you have seen such fixtures, and guess what they are for?
They often come across on video from this master. So, this is something like a corner clamp.
The author will show how you can make such irreplaceable helpers, and tell you why they are needed.
He marks out thick sheet plywood.
Then cuts the workpiece with a band saw.
So, this device has a different angle of inclination. On the one hand - 45, on the other - 22.5 degrees.
Now you need to create a sole for them. The master cuts it out of sandpaper.
Then glues it to the bottom of the fixture with second glue.
This is what a conventional dowel connection looks like at an angle of 120 degrees. But how to tighten it tightly?
He finds the center of this compound and draws a diagonal line.
Now applies stops to the joined parts. The part closest to you in the photo should be exactly in the center of the line.
Now clamps the middle part of the device with clamps. And sandpaper will not let him slip along the workpiece.
Lubricates the grooves with glue, connects the elements together.
And now the trick. Another clamp can easily rest against these protrusions. Moreover, the force will be evenly distributed throughout the connection.
Here is such a simple and simple method. Why do we need other angles on the device, I think you already guessed.
After grinding, a perfect joint is obtained without cracks and distortions.
Thanks to the author for a simple connection technique, and devices for this!
All good mood, good luck, and interesting ideas!
