My brother asked for help with buying the "iron horse". When looking at cars, one head is good and two is better. This event does not take place every day, so it is necessary to approach the communication with the sellers responsibly so as not to buy outright rubbish.
I decided to turn to a familiar seller of used cars, with a request to borrow a device that measures the thickness of the paint and varnish material. To which he was refused, because in the near future he will have transactions and he will need the device himself.
He did not limit himself to refusal, but told how you can make an amateur device from a syringe, magnet and ordinary rubber band. I decided to make it and show you at the same time.
First of all, you need to get a small magnet, for this we break the old droplet headphones, which are not difficult to find at home.
Almost all earbuds have a neodymium magnet, so it is not difficult to remove them.
This magnet should be glued to the rubber band of the syringe, having previously aligned the platform with a knife.
Flip through the gallery of 4 photos.The next step is to trim the piston rod.
And removing the syringe nozzle.
As a result, the following parts are obtained: Two photos in the gallery.
It is necessary to attach a rubber band to the piston, for this I made burrs with a soldering iron.
I tie an elastic band to them.
We connect two parts of the syringe into one.
We stretch the rubber band so that the joint of the rubber is at the mark "2" This will be the starting point.
We bring our newly-made "collective farm" to the pure metal. It turns out that the magnet comes off at 0.5 and less. This means that: The coating of the car is very thin, perhaps too polished before being sold. Whatever is "good".
If the magnet detaches from the iron of the car at around 2-1.5, then this means that there is a large layer of putty.
The ideal value would be a magnet pull off at around 1.5-0.5. The coating thickness is ideal.
How do you like such a simple homemade product? I think that she can help out and save the budget. Rate the article like! Thank you.
