How to make a simple vacuum chamber

Hello dear readers and homemade products !
When making various homemade products, for example, for deep oil impregnation of wood, working with cast epoxy resins, a vacuum chamber is often required.
In this article, the author of the YouTube channel “Damir Z” will tell you how you can make a small vacuum chamber for your home or workshop.
 How to make a simple vacuum chamber This project is quite simple to manufacture, does not require turning or welding, and can be repeated in home conditions.
Materials required for homemade products.

Manufacturing process .
So, the heart of the vacuum chamber will be the compressor from the refrigerator.
This model has three connections. One of them is pressed in, and this is the filler pipe. Of the remaining two, you need to determine the suction inlet. The easiest way to do this is to turn on the compressor and hold a piece of paper to the tube.

The basis for the entire device will be thick sheet plywood suitable size. The compressor is placed on the base, and the centers of the holes for the mounting bolts are marked.
How to make a simple vacuum chamber Drilled into plywood four holes according to the marking. Bolts are threaded from the bottom side, and the compressor is fixed with nuts.

It is extremely important not to scratch the surfaces, because this can not only break the tightness of the connection with the camera, but also (with a deep and long scratch) lead to destruction of the plate during evacuation.
How to make a simple vacuum chamber  How to make a simple vacuum chamber Such a pressure cooker will serve as a camera. It is preferred that it is made of thick walled stainless steel rather than aluminum. Such a container can withstand not only the increased pressure inside, generated by steam, but also a deep vacuum.
