Hello, dear readers and DIY!
As you know, clamps are indispensable helpers in the carpentry, and any other workshop.
F-shaped clamps can be used in many situations, but they cannot fix parts at an angle (without modifications) turns out. Of course, there are special, corner clamps for this, but not all of you need an “extra” set of highly specialized devices.
In this article, the author of the YouTube channel “Ohyo56” will tell you how to make replaceable jaws for a F-clamp and turn it into a corner.
This modification is very easy to manufacture, and it can be repeated in a small workshop. Of the materials, you can even get by with scraps of wood.
Materials necessary for home-made.
– A bar made of hard deciduous wood species
– Wood glue, sandpaper, double-sided tape, linseed oil.
Tools used by the author.
– Screwdriver, drilling machine – Forstner drills
– Circular saw, carriage , pushers
– Band saw
– Universal clamps for T-track
– Craft scalpel
– Tape measure, square, pencil
– Adjustable combination square, vice
– Protective gloves. < manufacturing process.
First of all, the master marks and cuts out four blanks of the same length from a wooden bar. For these tasks, only strong deciduous woods should be used. The dimensions of the blanks are selected depending on the size of the clamps themselves, and the tasks to be solved.
Then all the blocks are laid out in a row, and a strip of double-sided tape is glued to them.
Excess tape is cut off and the blanks are separated from each other.
All four parts are aligned and connected together in a block. For secure fixation, the master squeezes them in a carpenter's vice.
Now in the resulting block you need to cut out half of the T-shaped slot.
The depth of the first slot is equal to half the width of the clamping area. The width of the slot is equal to the thickness of the pressure pad.
Then, in several passes, the rest of the half of the T-shaped groove is formed.
Now the blocks can be disconnected. The author overdid it a little with scotch tape, and it was quite difficult.
Pairs of parts are fixed in a vice, and future cutouts are marked on them.
The first jaw will have a triangular shape with a right angle at the top.
The second sponge will have a mating cutout for the first one, also with a right angle at the base.
The workpieces are also glued together in pairs.
The parts are clamped in a vice while the glue hardens.
In order to make cuts at the desired angle of 45 degrees, the master glues the limiting bar to the square, and abuts the part against it.
The remaining triangles from cutting will be useful for fixing the jaws when drilling.
A Forstner drill with a diameter of about 10 mm.
The workpiece is held in place by two T-track clamps and a hole is drilled along the 90-degree angle. Such a hole is necessary so that the wood does not crack, as well as for a tighter fit of the workpieces to the working surfaces.
The craftsman glued sandpaper on a flat board, and smoothes the sides of the parts by hand.
On the working surfaces, you can see the “wavy” irregularities left by the band saw. This structure is quite even, and will even provide better adhesion to the fixed workpieces, so the master leaves it intact.
The edges of the parts are also slightly rounded by hand.
Almost everything is ready – you can put sponges on the clamp platforms and check their convergence.
The workpieces will be fixed between the jaws as follows.
It remains only to saturate the products with linseed oil, and after a couple of hours, remove the excess with a rag. This will give them a beautiful appearance, showing the natural texture of the wood, and also protect against moisture and cracking.
Everything is ready – now, at the right moment, an ordinary F-clamp can easily be converted into a corner clamp.
This way you can reduce the cost of purchasing clamps, which, as you know, are not enough in a carpentry workshop.
