Almost all masters need such a simple devicelike a clamp. But sometimes the length of her lips is not enough. For example, to press parts in the center of large sheets.
In this article, the author of the YouTube channel "TheDacchio", offers you an easy way to optimize a standard C-shaped clamp. He will show how to make elongated clips for her, without much damage to the original fixture.
Materials
- Steel profile pipe
- steel strip
- C-shaped clamp
- Two M12 bolts with washers and nuts
- Two M6 bolts, washers, nuts
- Spray paint.
Instruments, used by the author.
- Band-saw
- Screwdriver
- Welding machine
- Drilling machine
- Grinder, cutting discs, flap disc
- Vise, clamps, wrenches, hammer
- Countersink nozzle
- Roulette, ruler, marker, core.
Manufacturing process.
First, as always, the author begins by cutting blanks for future clips. He cuts them out of a steel profile pipe using a band saw. Be sure to use grease when sawing.
Then the author applies two guides of clamps to the clamp, and applies markings, the core of the drilling site.
Clamping the workpiece in a vice, drills a hole for the eyes.
Cuts eyes using a grinder with a cutting disc.
He tries on blanks to the base of the clamp, and marks the places for drilling.
Here, the author could not immediately get to the centers marked earlier. I had to insert sheet plywood into the eyes, then press the workpiece with a drill, and only then fix it with a clamp, and drill both sides in one go.
The author puts on eyelets on the clamp, marks the location of drilling on its base. Then, holding it in a vice, drills the necessary holes for clamps.
Having inserted bolts and having acquired nuts, checks the progress of the clamping screw.
Now collects clamp structures. First, it picks up all the elements between each other by welding.
And only after that thoroughly boils the seams.
Having made small rectangles for the “ears” of the clamping jaws, he marks and cores the drilling sites on the clamps. Drills holes in the clamps.
Rounds corners with a sweeping flap disc. So repeats with four blanks for sponges.
Then, on a drilling machine, all four blanks of the “ears” pass immediately, in order to avoid size deviations.
Drilled holes countersink.
Sets the "ears" of the clamps, fixes with bolts and nuts.
Now welds the soles to the ears. The author made them from the same steel strip.
It remains to weld the clamp washer to the guide.
The upper and lower position of the clamps of the author are satisfied.
Having painted all the details of the structure, collects it.
As can be seen here, a standard C-shaped clamp cannot reach the workpiece.
But the optimized version copes with this task even with a margin. Moreover, the clamps are able to clamp even a sheet of paper.
Here is such an innovation for the author. The clamping force will certainly be several times less than that of a standard clamp due to the fact that it works on the principle of a lever. Accordingly, it is desirable to increase the length of the handle on the clamp screw.
Thanks to the author for the original optimization of the standard clamp, and the expansion of its capabilities. In fact, this is a new home-made clamp, which deserves attention as home masters and professionals.
All good mood, tools and good luck!
