Repair collector do it yourself with electroplating
So the collectors are quite suitable for recovery.
On the left, from the stove, with the lamellas completely burned to the insulator, it will have to wind the cooler to the turn of the bare wire with a diameter of about 0.2 mm. In the middle of the starter, but already flowed to extension. It is noticeable to burnout one lamellae to the base and extinction of the rest, but the mounting of the lamella is not impaired, and the wires to the slats are welded. Standard diameter 45mm flowed to 41mm. To the right collector, too, from the stove, quite suitable for recovery without refinement, it is enough just to clean.
Anchor under the extension will have to prepare because it is not quite ordinary and make an improvised bath.
For this, the half of the plastic bottle is suitable. The anchor shaft must be wrapped with a scotch, and the collector's ends to smell the plasticine so that in vain to the ends of the lamellae, copper did not grow and so that the electrolyte between the shaft and the collector's insulator, the electrolyte contact is unacceptable. From the Colenip of PCV, you need to hurry the cork so that it is tightly included in the neck of the bottle from the inside.
The motor collector needs a piece of bare wire to connect all the lamellas together and hang on the crossbar in a simple jar with an electrolyte so that the electrolyte does not touch the hooks, but completely covered the place of wear.
The arrangement of the collector in the electrolyte, the anode serves as a tank from the burnt starter, its total area should be about twice the extensive surface. A shine folds with a spiral, slightly larger than the diameter of the vessel and when placed in the vessel fits tightly to the wall. The minus of the power supply is connected to the extensive part, plus to the tire. The current is selected from the calculation of 1,5a per 1 dm2. You can feed from the charger for the phone, and adjust the current by turning the light bulbs of different power. Light bulbs are still needed to protect against a possible CW on the bath.

Composition of electrolyte:
- Copper Summary - 200g
- Sulfuric acid 1.84 - 40G
- Alcohol - 5g
- Boiled water - 800ml.
- Alcohol can be replaced by the triple amount of vodka.
After a day, we get a completely visible view of the scorched collector.
But after the groove it looks like this, since copper hells, although not exactly, but much more than you need.
Of course, a small volume of the bath can be experimenting with the composition of the electrolyte, but whether it is necessary. With this mode, copper builds very hard, although not exactly. Slip the grooves between the lamellas can be a borders, or simply sharpened with a hacksaw blade and be sure to check for the lack of closures between the plates.
So it looks ready to assemble an anchor of the starter, his diameter has become 1mm more standard, but it does not interfere with anything, but is longer. On a small twist, you can see where there was burnt slats. On the right is ready for winding anchor of the motor, the collector is also increased by 1 mm. In this method, almost any collector can be restored, unless of course it fell apart.
