A broken part of a tool, especially during work, can spoil not only the process of work, but also the mood for further work. It’s good if, with the breakdown of an insignificant part, the tool has not failed, and they can still be worked on, before replacing this ill-fated part. In my case, for example, the pad between the frame and the container broke in the garden car.

The breakdown seems to be insignificant, and you can continue to work. But not so simple; with a more or less serious load, the wheelbarrow begins to lead in the direction from which the pad broke. This is very inconvenient when transporting heavy loads. Then I decided to remove the second overlay, for symmetry! I thought it would help.

Indeed, it helped - it stopped driving the car to the side. But she began to creak hellishly! Ears curl up! No lubricating oil helps. For a long time I could not stand it, and went to the nearest hardware store, for the part I needed, which, of course, was not there. To drive around the city, in search of the right thing, there was not the slightest desire. Then I decided to repair the broken thing myself. Today we’ll consider one of the options for how to assemble a thin plastic lining, chopped in half, together. This advice will greatly help those who are in a similar situation. This may not necessarily be a pad from a wheelbarrow. In this way, you can restore any plastic thing or part. At least until the original is purchased from the store.

You will need:


  • Pliers.
  • Pin.
  • Glue second.
  • Composite adhesive, type "cold welding".
  • A drill, the thickness of a cooked pin.
  • Bor machine or a small drill.
  • Small grinding disc for a bor machine.

First you need to check if any small pieces have fallen off and examine the repair object in more detail. If the repaired part has stiffening ribs, then the longitudinal ones will have to be removed. This can be done with pliers and a boron machine with a small grinding disc.

Further, in the most thick-walled places, with a drill of two millimeters, you need to drill holes into the part. Like this:

A depth of 4-5 millimeters. We will need these holes to reinforce the part. For greater strength. Next, we take the prepared pin, straighten it, and break it (or bite it off with wire cutters - who cares!) Into eight millimeter pieces.

Now, using a match, or thin wiring, lubricate the holes on the drilled half of the broken part, and stick the pins obtained from the pins into the holes.

We do everything extremely efficiently so that the glue does not seize in empty holes. Next, drill holes in the second half of the broken part. Strictly opposite the pins sticking out of the first half. If everything worked out as it should, we lubricate both halves in a split place with second glue, and stick into each other.

Now it's the turn of composite glue. I use the type of "cold welding" - a very convenient glue. There is not so much fuss with it as, for example, with the liquid components of epoxy glue. Yes, and it freezes much faster, but they are the same in terms of reliability of fastening.

In general, we break off, or cut off, the piece we need from the total mass, spray the palms with water, and carefully stir and knead the glue in the palms. To obtain a homogeneous mass.

Next, grease with a second glue the inner surface of the part being repaired, the one with which we broke the longitudinal stiffeners. And we sculpt cold welding on a greased surface.

After all the above procedures, we leave the part for several hours so that the glue is already set for sure, as it should.

Well, and in the end, install the restored part in its original place.

It turned out very well. Leads nothing, does not creak. You can load again as much as you can take, and how much the wheels are designed for!

The work itself took no more than an hour. The only negative: I had to wait a few hours until the glue finally set.

    Oh god, what a perversion! Sculpt all this and for what ?! For the sake of laying, not a wheelbarrow ... But just take a piece of rubber from the sole of the old shoe and cut this gasket? No?! Or is this car special? You have to shoot from it and then you need accuracy ?! The fact that the hands managed to restore the detail is commendable, but the whole story is a complete perversion of the brain.

    I would cut a spacer from the wood in the country house, or from two layers of plywood. And here is super glue and cold welding! If only, on the pin, from which he made the pins, he applied burrs with side cutters!

      Damn, for sure! Each owner of a garden cart in the house has a 3D printer under his bed ... and he knows anything about 3D modeling for anyone. And 100% he is ready to spend 10-20 hours to draw a part, and then print it ...

    People’s wheelbarrow went in cycles, but it would be necessary to turn brains on restoration of a plastic detail. I can’t glue the plastic. experienced many ways. Does not work. A really working way is to make a plastic electrode and make a seam. Steel studs can be heated and thrust. So learn more precisely .a Seam must be pierced, degreased and melted with a soldering iron / torch. then grind. if anyone knows a good glue for plastic, let me know.

      Some ABS plastics adhere well with acetone. It turns out a homogeneous cast seam. Then, if the part breaks, it is no longer along the seam but next. It is necessary to try on a fragment of a plastic part - if a drop of acetone melts it, then you can safely use it around the seam. Acetone evaporates quickly, so you need to act quickly. With a soft squirrel brush, apply acetone liberally to the fractures of the parts to be glued and quickly connect. You can once again walk along the seam with an acetone and wipe the seam with molten plastic with a brush. Toluene works the same way, but it is very poisonous.

    To make a mold out of plasticine and cast any number of parts from epoxy with a filler was not enough reasoning, apparently.

      Two-component silicone compound + plasticine mold = exact copy.

    Pins, as a tire for hardening the seam is a controversial solution. Drilling new holes, you loosen the platik. I would recommend gluing with a second glue a metal plate over a flat part, over all the areas of the lining, it would take on part of the loads. Cold welding is a good thing. I did not know what can be combined with cyanoacrylate, I’ll take note.

    Drill holes, so that the matching holes match ...
    How complicated and boring ..
    But bending a paper clip and melting it with a soldering iron or a heated nail is not easier? and then use the same soldering iron to smooth out the squeezed out plastic remains through a sheet of paper? Or do you need an unearthly beauty for a garden car?
    The idea is clear, robust, but the execution is unreasonably complicated.

    I have long bought a polymorph from the Chinese and, if necessary, sculpt everything that is necessary out of this plastic. This thing costs a penny, but really helps out.

    Flatten a piece of hose, poke holes. At the same time, replace the second one. Survive a wheelbarrow.

    it is necessary easier, in such cases, if space allows, it is necessary to strengthen the overlay (selection of material) -screws (bunch) -new holes. Vibration hose fire (conveyor belt), cut-drill-put

    The pressure on the part is two M8 threads + torsion while the pipe rolls relative to the body, more precisely, sliding on the pins is not a complete equality with. If the trolley is not used, then how new and lend to a neighbor let his head hurt. Then the temporary work is excellent. But the neighbor will see the catch. So what is the essence of this idleness?
    We fix the men forever, we cut the grid with steel wire 1 mm around the perimeter of all the plastic, we cut for consideration. We warm and press flush into the plastic. Findings:
    There is a form, reinforcement fastened the part better than before. The cart is like this, cars are being repaired. You can use a soldering iron or torch. The main point is to catch, the method can be any. But plastic with integrated fittings is no worse than a new part.
