With a little construction there is no reason to buy the mixer, as it is needed only once and making just a couple of cubic meters of concrete. For such purposes it is possible to do with their hands, spending almost 10 times less than the cost of the cheapest factory mixer.

Manufacturing process of concrete mixer
To rotate the mixers need to do 2 sets of bearings.
Support consists of cut strips with welded ring cut from a pipe.
At the top of the ring is cut across and its edges are welded eye from the corner. For reliability at the bottom between it and the strip are welded to the gusset plate or the same sections of the area. Then inserted into the support bearing and clamped by tightening the bolt in the lugs.
In the barrel to cut a hatch for loading concrete. First, cut one side lengthwise, then installed the hinges, and it is cut already full.
Next, you will set the lever latch.
To hatch has not failed, between the latches from the inside wall of the barrel is mounted on rivets or welded limiter.
In the center of the lid and the bottom of the barrel drilled holes 16 mm.
Then you need to weld the mixer with handles, which will mix concrete on the inside. To do this, use a section of pipe a couple of inches smaller inner height of the barrel. At the ends thereto are welded nuts M16. Then the pipe welded to the T-shaped vane of the valve. Then you want to weld to the hats of two M16 bolts with knob handle from the pipe.
The axis with blades placed in the barrel through the holes on the outside it screwed the knob bolts. You need to securely clamp the cover and the bottom of the barrel with nuts and washers to rotate with the axle. When clamping it is important to position the knob in the different direction.
From scraps of lumber to cobble together the legs for the concrete mixer. On the one hand they are connected with alosinae, on the other hand will be filled with the trough for draining the finished concrete. The mixer is attached to the legs just for support. It is desirable to make the legs high, so that it can be rotated while standing.
Mixer is designed for two. Due to the fact that the handles separated in different directions, it won’t turn over during the launch. As between the door and the drum there are gaps, then when mixing you can’t stop the door down. After mixing the hatch opens, and the concrete is discharged into the trough at the bottom.
