Greetings to all lovers of homemade products and those who just looked at the site in search of interesting ideas, which I want to share with you. Before that, I already told you how to make a convenient grip for carrying sheets of plywood or furniture boards, you can find homemade products in my profile. Now I am sharing another idea from this author. I just could not help but share it, because in his video he demonstrates these two ideas at once. Such a clamp is very useful for beginners welders who, having bought a welding machine, do something about the housework. Yes, and experienced welders, I think this homemade product will be interesting. This design is not at all difficult to manufacture and does not require a large set of materials (everyone can find what they need either in their garage or at the nearest scrap metal collection point) and tools. At the end of the article I will fix a video from the author, this idea will be number 2. The dimensions of some details can be determined from the photo with a ruler, the rest can be estimated in place.
And so, let's get started))
* a piece of a round pipe (diameter somewhere around 70-80 mm),
* metal corner with a shelf 70-80 mm,
* metal strip with a thickness of about 3-4 mm and a width equal to the width of the corner shelf,
* threaded rods and nuts for them,
* nuts slightly smaller,
* metal bar (diameter about 10-12 mm),
* bolts for small nuts.
* welding machine,
* cutting machine (grinder),
* marking tool (pencil, tape measure),
* drilling machine (you can drill) and a set of drills,
* magnetic squares,
First, we make the main part of the clamp (you can call it central, so probably the boot is more correct). We clamp the pipe in a vice, put a mark on it and cut off a segment of the required length (it is generally selected individually, and depends on the maximum section of the pipe that we plan to weld), the author has it equal to 3 cm.On the pipe, in the middle, using chalk and a ruler , draw two parallel lines around the circumference. But not for the whole circle, but about half. Drill holes along the edges between the lines. Then we cut out a sector with a grinder, we get a groove. We process its edges with a file.
We take a corner, hold it in a vice and make two marks of 3 cm on a tape measure (first 3, then 6 cm). We draw straight lines, perpendicular to the shelf and cut off two parts along them. We also process the edges with a file.
Then we take a bolt of a suitable size (the diameter should be equal to the width of the groove on the pipe). Clamp it in a vice and grind it at an angle (the same as the angle between the corner shelves) grind off any opposite edges.
Now we take the previously prepared pipe and combine it with a corner to which the bolt was welded. From the inside of the pipe, screw the nuts onto the bolt. Then we take the second corner and attach it to the pipe next to the first one, weld it on.
The turn of the strip has come. We put two marks on it with a length of about 5.5 cm.We cut off two parts. We process the edges at the ends either with a file or on emery. We try on the plates to the corner shelves. Having set everything straight, we weld perpendicularly, strictly at right angles. To keep everything neat, we use magnetic squares.
Next, we take a nut with a round outer surface. Draw two lines around the entire outer circumference, as shown in the photo. We cut it into two identical parts. We also need several washers, four with a diameter equal to the diameter of the cut parts and two smaller ones. We arrange the washers and nuts in the order shown in the photo, then we weld everything, we clean all the seams.
As a result, we should get the following details.
Next, we take two threaded rods, two nuts for them and two more nuts. The diameter is equal to the diameter of the studs. We screw the large nuts onto the studs, and weld the smaller ones to the ends. Don't forget to clean the seams. We also weld large nuts on the other sides of the studs. We clean up.
More us you will need nuts for the studs, but only elongated, we also screw them onto the studs. After that, to the studs at the ends, to which smaller nuts are welded, we fasten the previously prepared parts with shortened screws.
At this stage, we collect our clamp. We put the pin on the strip on the base so that the nut with the bar is at the very edge. We rotate the hairpin so that it rests against the pipe wall. We fix the part on the plate by welding, as shown in the photo. We weld the second stud in the same way to the second plate. We paint the fixture in the desired color and check the right angle with a square. All is ready.
You can try our device is in business. In the photo below, the author demonstrates in what cases this clamp can be used. Up to the point that it can be used to weld the workpiece at the desired angle to any already installed structure (last couple of photos).
