Will need
- New slider to match the zipper slider number.
- Stationery knife.
- Scissors.
- A piece of aluminum plate, 1 mm thick.
- Fine-nose pliers (you can use wire cutters).
- A piece of paraffin from a candle.
Replacing the slider
So, let's carefully examine the faulty zipper.
If there is no visible damage on the teeth, then the problem is definitely in the runner. At first glance, it is structured quite primitively. In fact, there is something to enjoy there. The connecting grooves may come apart, or the disconnecting partition may come off. The metal from which the slider is made is quite fragile. If the identified problem is in the slider, then it must be removed from the zipper. To do this, at the beginning of the zipper, between the second and third teeth of the zipper, we make an incision.
The length of the tooth. We repeat the same procedure on the opposite side. Next, we pull the broken slider in the direction of the ripped edges. It will slide off the edges without any problems.
Now you need to insert a new slider into the zipper. There won't be any problems with this either, if the slider fits. For information: each zipper fastener has a number on the slider corresponding to the numbered size of the zipper.
But it happens (especially on branded products) that the number on the slider is not indicated. Then we visually select the most similar slider. You can buy such a slider in jewelry stores, or, as a last resort, from the same specialist in the service department. It costs a penny. So, we insert the slider.If everything is in order and the zipper is fastened, then you must immediately press down the connecting grooves with pliers. Like this:
This must be done because the new runners come with widened grooves for better ease of installation. So the lightning works. Next you need to connect the cut zipper links. To do this, cut a strip of 2×10 mm from the aluminum plate. We sharpen it at both ends and make a bracket out of it.
We install, using pliers, a bracket at the site of the break. In general, we make sure that the new slider does not reach the break point.
By the way, I don’t recommend using instant glue in this case instead of an aluminum bracket - it will ruin the entire zipper. Well, finally, rub the zipper teeth with paraffin.
You can wax it. This is an excellent lubricant for this type of lock. You can treat the teeth with graphite from a simple pencil, instead of paraffin, but this is tedious and time-consuming. In general, it's up to you to decide. You can use any type of the above lubricants, except machine and gun oil. After applying oil, the brass zipper may stick and jam. In this simple way you can save several hundred rubles.
