In this review, the author shows the manufacturing process of a vacuum chamber for the impregnation and stabilization of wood blanks.
Wood preforms that have been processed in a vacuum chamber have noticeably improved performance.
This allows you to make various parts and decorative products that are practically not affected by the harmful effects of external aggressive factors.
We recommend reading: a vacuum chamber made of a freon compressor and a pan.
The main stages of work
To make a vacuum chamber, the author uses a piece of steel pipe. The diameter of the pipe can be different and depends on what size of the workpiece you plan to process.
Then you will need to cut a circle from a sheet of metal and weld it to the bottom of the pipe. Welds must be cleaned with a grinder.
In the upper part of the "glass", the author drills holes for pumping and bleeding air, and then welds pipe segments (one with an internal thread, the second with an external one).
Also, in the upper part of the chamber, from the outside, the master welds pieces of the square, and to them are hairpin segments.
Next, you will need to make a cover. Cut off a piece of plexiglass of the right size and drill holes in it. We put on the studs and fix the wing nuts.
Between a pipe and a plexiglass cover, the author places a sealing ring - a gasket from an old street lamp.
On a piece of threaded pipe welded to the camera, the master winds a corner. Then comes the ball valve, check valve and fitting.
The final touch - and you're done!
Another important element is the automobile hand pump. In order for it to be able to pump air out of the chamber, it needs to be slightly modified.
The first step is to remove the ball from the pump fitting by drilling a hole in it. Then you need to turn the cuff on the pump piston upside down.
After the pump has been assembled, we put the hose on the fitting and fix it with a hose clamp. We install the cover, and the vacuum chamber is ready.
True, this design lacks a vacuum gauge. You can buy it or make it yourself (for example, from a pressure gauge for a gas welding reducer).
