Hello to all homemade products! In this article, we will consider making an interesting homemade product. Namely, we will consider the manufacture of a special mount for a grinder (grinder), which allows you to polish metal pipes of various diameters and different shapes exactly to shine. This homemade product will certainly come in handy for those who often make something out of metal. With the help of this homemade product, you can significantly save time when grinding and polishing products, in addition to metal parts, you can grind timber and boards. As befits any homemade product, our homemade product will be assembled from the most simple and available materials, structurally it will not have any complex mechanisms, so everyone can assemble it. It is also worth noting the fact that the design itself is quite versatile, and will fit the vast majority of grinders. Well, well, I think you shouldn't delay with a long preface, let's go.
For this nozzle we need the following, namely:
– Metal stripes
– Ordinary nuts and wing nuts
– Metal washers
From the tools we also need the following:
– Welding machine < br> – All the necessary accessories for working with the welding machine
– Construction corner
– Drilling machine or ordinary drill
– A set of drills of the required diameter
– Some lubricating oil
– Cutting and grinding discs for a grinder
– Center punch
Making attachments for a grinding machine:
Let's start assembling this homemade product from its frame. To do this, we need to find a metal strip of about the same width and thickness as the metal strip taken by the author of the homemade product (see photo). From this strip, you must cut two pieces of the same length. The length of these segments should be about 20 cm, this length will be more than enough for our future instrument. We measure the required length of the segments, then carefully saw off the segments of the required length with a grinder.
After the sections of the required length have been sawed off from the metal strip, it is necessary to drill two through holes in them. One of the holes should be located at the edge of the metal strip, and the other should be slightly off-center (see photo). Taking a marker and a ruler, we mark the places for drilling holes, then for a more convenient initial setting of the drill, we knock out the holes in the places marked with a marker, using a center punch and a hammer.
Having marked the places for drilling the holes, we directly proceed to drilling the holes themselves. For this we will use a drilling machine, but you can do with an ordinary hand drill. Since we will be drilling relatively thick metal, I recommend that you lubricate the drill with any lubricating oil to reduce friction and, accordingly, reduce the heating of the drill, in this way you minimize the risk of overheating of the drill and its imminent failure.
Next, we need to again take the same metal strip that we used at the very beginning, and from this metal strip we need to saw off four more identical segments, about the same length as that of the author of the homemade product (later it will be clear what is what). We mark the segments on the strip and carefully, using a grinder with a cutting disc put on it, saw off the blanks, securing the strip in a vice. As a result, you should have the same blanks as the author in the photo below.
After that, the author of the homemade product took a couple of screws with a hexagon inside and screwed one nut onto them, so that the screw protruded from the nut to a length equal to the width of the metal strips with holes. He hammered these blanks (pressed) into the previously mentioned holes in the metal plates with the help of a blade. This means that the diameter of these screws must match the diameter of the holes in the plate. It is also worth noting that in this case it is not necessary to use such specific screws, but you can replace them, for example, with bolts from which you can cut off the head or with a metal stud of a suitable diameter.
As you probably guessed, such a connection of the screws to the plate is very unreliable. Therefore, it must be strengthened, for this we use a welding machine, which needs to weld the screw from the reverse side. Having welded the screw to the plate, grind the joint so that nothing “sticks out” from the plate and the part looks monolithic.
Again, from the same metal strip, cut out a couple of segments, no more than 10 centimeters long. Along the edges of these segments we will drill one through hole from each edge (see photo).
And we move on to the manufacture of the following elements. Namely, we need to take our newly cut small rectangles with through holes drilled in them. We weld previously cut long blanks to these rectangles. Two blanks for one short rectangle. We weld them in exactly the same way as the author of the homemade product in the photo below does it, that is, leaving a small distance between them, the rectangles themselves should be located exactly perpendicular to the small ones and parallel to each other (see photo). We weld and don't forget to grind the welded seams.
We turn to the manufacture of rollers on which our nozzle will roll on the surface. There is nothing difficult here, we will use ordinary bearings as such rollers. The axles on which the bearings will be attached and rotated will be bolts, and nuts will be fastened from falling out. We insert the bolts into the holes that are drilled in short rectangles, put them on the bearing, then screw them on the nut. We check how the workpieces roll, the bearings should rotate freely, and the workpieces should roll smoothly. If the bearings touch the nuts and a metal rectangle, you can install a metal washer between them with a smaller diameter than the outer diameter of the bearing.
We turn directly to the grinder itself, for which this attachment was assembled. In fact, all structural elements are ready, it remains only to correctly assemble into one. We return to our blanks, to which the screws were previously welded. We should install them on the grinder, we do it as follows, namely: remove the grinder's handle, apply our workpiece with a screw welded to the outside, match the holes in the plate with the mounting hole on the grinder, and screw a fastening screw of a suitable length into them. We tighten the screw securely so that the workpiece with the screw is tightly pressed and does not rotate around its axis.
Since the grinders often have two mounting holes for the handle, and the second same hole is located on the opposite side of the first hole. Therefore, we turn over the grinder and, in the same way, fasten the second metal blank with a welded screw. And move on to installing the rollers.
Now we just have to fix the rollers, for this we put on a blank with rollers in such a way that the welded screw on the grinder mount is located between two long metal strips (see photo). We put a washer on this screw, of such a size that it fits snugly on these two strips at once. We fix the element with a nut, since this is a knot that will need to be constantly tightened and loosened, I recommend using the lamb nuts, in fact, which is what the author of this homemade product did. We attach the second blank in the same way.
All is ready! As a result, we got an interesting homemade product that will repeatedly help you in grinding and polishing any details.
