Hello, dear readers and homemade products!
As you know, most modern sealants (various silicones, liquid nails) are packed in convenient disposable syringe tubes, and their squeezing is most often done using special “pistols”.
Make a large volume work with a standard “pistol” is rather difficult, and the uniformity of the seam application suffers.
In this article, Alexander, the author of the YouTube channel “Master Sh”, will tell you how you can make a simple device for squeezing out the sealant using a screwdriver. It can also serve as an emergency replacement for the “pistol”, because it can be done in a few minutes.
Materials necessary for homemade.
– Steel stud, nut M10
– Sheet plywood or a piece of plank
– Yoke with a wing
– Seconds glue, soda, linseed oil.
Tools used by the author.
– A set of crowns for wood and metal – – Pen drills for wood – – Semi-automatic core drill, vice – – Drill bits for metal
– Tap holder, tap
– Grinder, cut-off wheel
– Screwdriver with a set of bits
– Roulette, marker.
So, a steel pin will serve as a replacement for the standard rod. Almost a complete replacement of the entire pistol design will be … a piece of wood.
a plate in a vice, from it you need to cut a disc with a diameter of 45 mm (it is equal to the inner diameter of the sealant tube). This operation is easily accomplished with a wood crown .

Installing the M10 nut in its place (and it easily fits into the 18 mm hole), the author fills the seam with regular soda. br> After removing the excess soda, a few drops of second glue are added to the seam. The composition freezes almost instantly, and is ready to withstand the load.
< a href = "https://usamodelkina.ru/uploads/posts/2021-07/1625523633_sil-039.jpg" rel = "prettyPhoto"> The surfaces of the resulting part can be sanded with an abrasive sponge or sandpaper.
If there is an impregnation for wood, for example, linseed oil – then it can be additionally processed on wooden surfaces.
Next, from the M10 hairpin, you need to cut a piece slightly longer than the tube. It is about 220 mm.
After adding a little grease, using a tap , an M4 thread is cut into the hole.
Now you need to pick up an M4 screw with an enlarged head. It should be of such length that it does not screw in to the end, and there is a small gap of 3-4 mm.
< a href = "https://usamodelkina.ru/uploads/posts/2021-07/1625523637_sil-072.jpg" rel = "prettyPhoto"> Hairpin is fixed in the chuck of the screwdriver, and the thread at its second end is grinded with a flap wiper.
The pressure washer can be removed from a broken pistol.
< a href = "https://usamodelkina.ru/uploads/posts/2021-07/1625523639_sil-083.jpg" rel = "prettyPhoto"> So, all the parts are ready, and you can assemble the device.
The first screw is screwed onto the lead screw homemade “nut”.
One or a pair of small washers is placed under the pressure washer, and it is screwed to the screw.
< a href = "https://usamodelkina.ru/uploads/posts/2021-07/1625523641_sil-099.jpg" rel = "prettyPhoto"> A collar with a lamb is put on the tail part of the tube. A disc is inserted inside, and clamped with a clamp. To prevent it from turning (if you miss the diameter), you can put a piece of sandpaper.
< a href = "https://usamodelkina.ru/uploads/posts/2021-07/1625523643_sil-111.jpg" rel = "prettyPhoto"> Everything is ready, you can apply sealant.
The first drawback of this design is its long length – it will be difficult to manipulate in hard-to-reach places.
The second point is that it is quite difficult to instantly stop the sealant supply, for this you need to turn on the reverse and make a couple of turns.
I thank Alexander for the simple design of the device for extruding sealant using a screwdriver.
Good mood, good health, and interesting ideas to everyone!
