Hello, dear readers and DIY!
Many of You often use conventional pin connection, and You are aware of the nuances that arise when marking and drilling holes.
In this article, the author of the YouTube channel “el Rincon de Vicente” will tell You how he made multifunction jig for accurate drilling of holes for dowels, greatly accelerates this process because of the reduction of the amount of preparatory work.
This fixture is easy to make, even with minimal set of tools.
— Oak boards, round dowels
— Bearings Z809 8×22×7 mm, analogue 608ZZ
— The M8 screws, screws for wood,
— Drop furniture nut M8
— Sandpaper, PVA glue, two-component epoxy glue.
The tools used by the author.
— Milling machine
— Drilling machine
— Feather drills on a tree, crown
— Drill bits for wood with countersink
— Vise, awl, hammer
— An angle grinder, diamond cutting disc
— Jigsaws machine
— Marking a marking gauge, pencil, screwdriver.
The process of making.
So the author cut out of an oak plank a template for the base size 100X200 mm.
In it, he performs a marking with marking a surface gauge.
Along the dashed lines should make a through slot with a length 70 and a width of 8 mm. This operation is performed using the end mill on the machine, however, you can do hand router.
This groove will move the screw, which is designed for fixing the movable stop.
All the holes must be drilled with extreme precision on the drill made a pilot hole with a thin drill.
Two holes for the pins are made of 7.75 mm drill bit Is necessary for a tight installation pins without the use of glue.
The next hole you need to make the same diameter as the dowel used. In the author’s case is 8 mm.
The fourth blind hole is made from two sides of the base 22-mm pen drill. It will be pressed on bearings.
All the surface polished with emery paper manually.
Now the master presses into its place both bearing 608ZZ.
Instead of ball bearings on this place, you can install a steel tube with an inner diameter of 8 mm.
The author decides to shift the edge of the future cut closer to the bearing, for this he puts the awl another mark, and drill a hole 8 mm in diameter.
That the base wasn’t so bulky, it was decided to remove parts that are not needed.
He retreats from the edge to 30 mm, space centres, taking account of the diameter of the pen drill 30 mm, and drill a few through holes.
Without departing from the boring work hard, using the crown, the author cut that’s a pretty penny for handle clamping screw.
The excess material he cuts jigsaws on the machine.
This stanochek made of a conventional electric jigsaw, and in some cases can replace a band saw. You can do by reading the following article.
On the same machine is marked and made a slit width which should be strictly 8 mm.
The author now proceeds to manufacture movable stop. He cut the workpiece, equal to the width of the narrow part of the base, and a length of 10 cm.
To the sides of the master need to tie two limiter that will not allow the focus to stray in different directions. In thin plywood plates made pilot holes using drill bits for wood with countersink.
Plates are glued to the base, and are fixed by screws with countersunk heads.
Excess glue is better to remove it with a rag.
Next, you need two M8 bolts. The first of these will be split into two pins.
In the center is made of logs previously drilled blind hole with a diameter of 12 mm under the bolt head.
Then made a through hole with a diameter of 8 mm.
The bolt is glued into the handle with two part epoxy glue.
So, all the parts for the conductor is ready, and the first in its place zamalchivayutsya the pins from the bolt M8.
It is extremely important that they be installed strictly perpendicular to the substrate surface.
Now to the base is applied to the movable stop, and he transferred the outline of the cutout for the bolt.
Exactly in the center of this circuit is drilled 10 mm hole.
In this hole is pressed a drive nut M8 furniture.
Of course, we can further drill out the bore hole to its edges to sit flush with the surface.
It remains to tie the emphasis of the clamping screw through the slot in the base.
Fixture finish. In addition, you should impregnate all wood surfaces with linseed oil to protect from moisture.
Now the wizard will show you three primary applications of this conductor.
As a first example, he will connect the wide edge of the two boards at an angle of 90 degrees.
Fixing the first workpiece on the workbench, it is imposed on the conductor pins down.
The pins are located on opposite sides of the workpiece. Then the conductor rotated so that they rested on the edge.
Notice, no pre-marking wizard does not, that’s the beauty of this device!
Wound on the drill bit a piece of masking tape, the author creates a label drilling depth. So he drills two holes for the dowel, stopping the process when the mark aligns with the top edge of the bearing.
Dowels with a diameter of 8 mm are installed in the prepared holes.
Now you need to flip the jig up pins and place it on a peg mounted bearing.
Then to the part moves the focus so that the entire surface was pressed to the plane of the part. Remains to hold the screw, and the desired distance from the edge recorded.
And now the most interesting.
The first workpiece is placed on top of the second, in which we should return holes for the dowels.
The slot of the conductor coincides with the core of the beam, and it moves together with the first workpiece as long as the emphasis is not pressed to the edge of the second part.
This operation is repeated with both sides of the workpiece, after which the components are fixed with clamps.
It remains to combine the neckline of the emphasis with each of the dowels, and drill holes.
Finally, it is possible to connect the workpiece. Perfect connection is obtained without markup!
But what if you want to make a T-shaped connection?
The first thing we have to note the line of the Central line, along which will be installed the second part.
The first part with the already installed dowels will be taken from the first experiment.
She also placed on top of the second panel, parallel to the marked line.
With the conductor removed the movable stop, the centerline on the workpiece and conductor are combined. The second part that is pressed against the conductor, is fixed by clamps, and running the drill holes.
Everything is ready, details you can connect, and test a square.
The last trick allows you to duplicate the response of the holes in the parts during Assembly of the furniture panels.
Again a peg is put on the conductor, the emphasis is pressed against the edge of the part and is fixed with a screw.
The second part is tightened together with the first clamp so that their edges coincide.
Now set the peg serves to guide a conductor. Remains to press the conductor second parts, and make holes in it.
And this time the master got a great connection without markup.
I thank the author for the idea simple but useful tools for the carpentry workshop!
All good mood, sound health, and interesting ideas!
